How Cancer Works

A diagnosis of cancer can be devastating. And there is good reason for this fear -- Cancer is the second leading cause of death in the United States next to heart disease, and will claim more than half a million lives this year.

The good news is that many forms of cancer can be avoided, and with early detection, a great number can be cured. In this article, we will look at the many faces of cancer so that you can understand the disease and its treatment, and also so that you learn about steps you can take to limit your exposure!

What we think of as "Cancer" is actually a group of more than one hundred separate diseases. These diseases are all characterized by an abnormal and unregulated growth of cells. This growth destroys surrounding body tissues and may spread to other parts of the body in a process that is known as metastasis. You have probably heard of all of these different types of cancer:
  • Skin cancer (squamous cell carcinoma and basal cell carcinoma being the most common)
  • Lung cancer
  • Brain cancer
  • Breast cancer
  • Prostate cancer
  • Colon cancer
  • Ovarian cancer
  • Leukemia
  • Lymphoma

There are many others as well.

Cancer can develop anywhere in the body, and at any age. Unlike infectious diseases such as AIDS, the flu (influenza), or tuberculosis, cancer is not contagious - cancer is usually caused by genetic damage that happens inside an individual cell. Cells affected by cancer are called malignant cells. Malignant cells are different from normal cells in the body in that they divide (in most cases) much more rapidly than they should. This is important to know because many drugs used to fight cancer (antineoplastic or anticancer drugs) attack malignant cells during the active phase of cell division.

You may know someone who has had cancer, and his or her hair fell out during treatment. That happened because the anticancer drug(s) affected the normal hair follicle cells, which divide rapidly, as well as the rapidly-dividing malignant cells.

When cells divide at an accelerated rate, they often begin to form a mass of tissue called a tumor. The tumor is fed by nutrients that diffuse through neighboring blood vessels and can also grow by forming a substance called tumor angiogenesis (vessel forming) factor. This factor stimulates the growth of an independent blood supply to the tumor. Tumors can cause destruction in three common ways:

  • Tumors put pressure on nearby tissues and/or organs.
  • Tumors invade tissues and organs directly (direct extension), often damaging or disabling them in the process.
  • Tumors make invaded tissues and/or organs susceptible to infection.

Tumors can also release substances that destroy tissues in close proximity to them.
One of the frightening things about cancer is the possibility of metastasis. This is the process where millions of malignant cells are released from the tumor (the primary) into the bloodstream. Fortunately, most of these cells are killed by trauma produced while traveling within the blood vessel walls, or by circulating cells from the immune system, like the Natural Killer (NK) cells and other T lymphocytes.

Other immune cells that battle malignant cells are macrophages, antigen-presenting cells, and substances produced by immune cells called lymphokines. One common lymphokine is called interleukin-2 (IL-2) or interferon. (See How the Immune System Works for details on these different components of the immune system.) In some cases, the circulating malignant cells survive and adhere to the inner muscular lining of the blood vessel walls. Here the process of tumor formation can begin in a different area of the body (the secondary), causing further destruction.

Cancer is caused by a number of factors, some of which we can control, and some we cannot. One of the uncontrollable factors is the presence of gene mutations. One type of gene that plays a role in normal cell growth -- an oncogene -- can be altered to contribute to the uncontrolled growth of a tumor. Oncogenes affect the way cells use energy and multiply. For example, in some cancers, the ras gene (an oncogene) is mutated, and produces a protein that stimulates cells to divide prematurely. Other oncogenes, such as C-myc and C-erb B-2, when amplified, are implicated in small cell lung cancer and breast cancer, respectively.

Mutations in tumor suppressor genes are another common cause of cancer. As you might expect, a tumor supressor gene is supposed to prevent tumors. But when these genes are damaged, they can allow cancer to develop instead of preventing it. One of these genes, p53, normally prevents cells with abnormal DNA from surviving. When p53 is defective, these cells with abnormal DNA survive and can multiply, increasing the probability of developing cancer.
Certain cancers are associated with chromosomal abnormalities. Chromosomes are located within the nucleus of our cells, and contain our genes. When genes are missing, duplicated, or rearranged, a predisposition to develop a tumor is increased. Certain leukemias, sarcomas, lymphomas, and others tumors are associated with chromosomal abnormalities.

There are also viruses associated with cancer. The human papillomavirus (HPV) that causes genital warts is associated with carcinoma of the cervix, and the Epstein-Barr virus that causes infectious mononucleosis, is associated with Burkitt's lymphoma. Diseases or drugs that affect the immune system can also increase the risk for certain cancers. The disease AIDS, for instance, is associated with a high risk of two types of cancer, namely, Kaposi's sarcoma and lymphoma.

Exposure to ionizing radiation can increase the risk of certain cancers. X-rays used to treat disorders such as acne or adenoid enlargement can increase the risk of certain types of leukemias and lymphomas.

Fortunately, there are also factors under our control that can increase the risk of getting cancer, and can therefore be avoided. There are substances called carcinogens (cancer-forming agents) that can increase the risk of getting cancer. Some common carcinogens include:

  • Arsenic, asbestos, and nickel, which can cause lung and other cancers
  • Benzene, which can cause leukemia
  • Formaldehyde, which can cause nasal and nasopharyngeal cancer
    and many others...

Carcinogens that are associated with a person's lifestyle include alcohol, which increases the risk of oral, esophageal, and oropharyngeal cancer, and tobacco, which causes lung, head and neck, esophageal, and bladder cancer. Smokeless or chewing tobacco can also increase the risk of oral cancer.

Unprotected exposure to sunlight (ultraviolet radiation) is associated with skin cancer. The main cancers caused by sunlight are basal cell carcinoma, squamous cell carcinoma, and malignant melanoma.

Pathology of Tuberculosis

General Features

Mycobacterium tuberculosis is the organism that is the causative agent for tuberculosis (TB). There are other "atypical" mycobacteria such as M. kansasii that may produced a similar clincal and pathologic appearance of disease. M. avium-intracellulare (MAI) seen in immunocompromised hosts (particularly in persons with AIDS) is not primarily a pulmonary infection in terms of its organ distribution (mostly in organs of the mononuclear phagocyte system).

Tuberculosis is becoming a world-wide problem. War, famine, homelessness, and a lack of medical care all contribute to the increasing incidence of tuberculosis among disadvantaged persons. Since TB is easily transmissible between persons, then the increase in TB in any segment of the population represents a threat to all segments of the population. This means that it is important to institute and maintain appropriate public health measures, including screening, vaccination (where deemed of value), and treatment. A laxity of public health measures will contribute to an increase in cases. Failure of adequate treatment promotes the development of resistant strains of tuberculosis.

Patterns of Infection
There are two major patterns of disease with TB:
  • Primary tuberculosis: seen as an initial infection, usually in children. The initial focus of infection is a small subpleural granuloma accompanied by granulomatous hilar lymph node infection. Together, these make up the Ghon complex. In nearly all cases, these granulomas resolve and there is no further spread of the infection.
  • Secondary tuberculosis: seen mostly in adults as a reactivation of previous infection (or reinfection), particularly when health status declines. The granulomatous inflammation is much more florid and widespread. Typically, the upper lung lobes are most affected, and cavitation can occur.

When resistance to infection is particularly poor, a "miliary" pattern of spread can occur in which there are a myriad of small millet seed (1-3 mm) sized granulomas, either in lung or in other organs.

Dissemination of tuberculosis outside of lungs can lead to the appearance of a number of uncommon findings with characteristic patterns:

  • Skeletal Tuberculosis: Tuberculous osteomyelitis involves mainly the thoracic and lumbar vertebrae (known as Pott's disease) followed by knee and hip. There is extensive necrosis and bony destruction with compressed fractures (with kyphosis) and extension to soft tissues, including psoas "cold" abscess.
  • Genital Tract Tuberculosis: Tuberculous salpingitis and endometritis result from dissemination of tuberculosis to the fallopian tube that leads to granulomatous salpingitis, which can drain into the endometrial cavity and cause a granulomatous endometritis with irregular menstrual bleeding and infertility. In the male, tuberculosis involves prostate and epididymis most often with non-tender induration and infertility.
  • Urinary Tract Tuberculosis: A "sterile pyuria" with WBC's present in urine but a negative routine bacterial culture may suggest the diagnosis of renal tuberculosis. Progressive destruction of renal parenchyma occurs if not treated. Drainage to the ureters can lead to inflammation with ureteral stricture.
  • CNS Tuberculosis: A meningeal pattern of spread can occur, and the cerebrospinal fluid typically shows a high protein, low glucose, and lymphocytosis. The base of the brain is often involved, so that various cranial nerve signs may be present. Rarely, a solitary granuloma, or "tuberculoma", may form and manifest with seizures.
  • Gastrointestinal Tuberculosis: This is uncommon today because routine pasteurization of milk has eliminated Mycobacterium bovis infections. However, M. tuberculosis organisms coughed up in sputum may be swallowed into the GI tract. The classic lesions are circumferential ulcerations with stricture of the small intestine. There is a predilection for ileocecal involvement because of the abundant lymphoid tissue and slower rate of passage of lumenal contents.
  • Adrenal Tuberculosis: Spread of tuberculosis to adrenals is usually bilateral, so that both adrenals are markedly enlarged. Destruction of cortex leads to Addison's disease.
  • Scrofula: Tuberculous lymphadenitis of the cervical nodes may produce a mass of firm, matted nodes just under the mandible. There can be chronic draining fistulous tracts to overlying skin. This complication may appear in children, and Mycobacterium scrofulaceum may be cultured.
  • Cardiac Tuberculosis: The pericardium is the usual site for tuberculous infection of heart. The result is a granulomatous pericarditis that can be hemorrhagic. If extensive and chronic, there can be fibrosis with calcification, leading to a constrictive pericarditis.

Microscopic Findings

Microscopically, the inflammation produced with TB infection is granulomatous, with epithelioid macrophages and Langhans giant cells along with lymphocytes, plasma cells, maybe a few PMN's, fibroblasts with collagen, and characteristic caseous necrosis in the center. The inflammatory response is mediated by a type IV hypersensitivity reaction. This can be utilized as a basis for diagnosis by a TB skin test. An acid fast stain (Ziehl-Neelsen or Kinyoun's acid fast stains) will show the organisms as slender red rods. An auramine stain of the organisms as viewed under fluorescence microscopy will be easier to screen and more organisms will be apparent. The most common specimen screened is sputum, but the histologic stains can also be performed on tissues or other body fluids. Culture of sputum or tissues or other body fluids can be done to determine drug sensitivities.

Tuberculin Skin Testing
Skin testing for tuberculosis is useful in countries where the incidence of tuberculosis is low, and the health care system works well to detect and treat new cases. In countries where BCG vaccination has been widely used, the TB skin test is not useful, because persons vaccinated with BCG will have a positive skin test.

The TB skin test is based upon the type 4 hypersensitivity reaction. If a previous TB infection has occurred, then there are sensitized lymphocytes that can react to another encounter with antigens from TB organisms. For the TB skin test, a measured amount (the intermediate strength of 5 tuberculin units, used in North America) of tuberculin purified protein derivative (PPD) is injected intracutaneously to form a small wheal, typically on the forearm. In 48 to 72 hours, a positive reaction is marked by an area of red induration that can be measured by gentle palpation (redness from itching and scratching doesn't count). Reactions over 10 mm in size are considered positive in non-immunocompromised persons.

Repeated testing may increase the size of the reaction (induration), but repeated TB skin testing will not lead to a positive test in a person not infected by TB. Anergy, or absence of PPD reactivity in persons infected with TB, can occur in immunocompromised persons, or it may even occur in persons newly infected with TB, or in persons with miliary TB.

Cancer and Tumors

It is important to note that not all tumors are cancerous. Tumors can be either malignant or benign. A malignant tumor is cancer, and a benign tumor is not. One main difference between a benign tumor and a malignant tumor is that a benign tumor will not spread (metastasize) to distant parts of the body, and usually it will not grow back once removed. A benign tumor is either surgically removed, or it may be left in place and simply observed to see what it does. The decision to remove or observe depends on the tumor's size, type and location.

Guide to Quitting Smoking

The US Surgeon General has stated, "Smoking cessation (stopping smoking) represents the single most important step that smokers can take to enhance the length and quality of their lives."
Quitting smoking is not easy, but it can be done. To have the best chance of quitting successfully, you need to know what you’re up against, what your options are, and where to go for help. This document is intended to provide you with this information.

Why Is It So Hard to Quit Smoking?
Mark Twain said, "Quitting smoking is easy. I've done it a thousand times." Maybe you've tried to quit too. Why is quitting and staying quit hard for so many people? The answer is nicotine.

Nicotine
Nicotine is a drug found naturally in tobacco. It is highly addictive – as addictive as heroin or cocaine. Over time, the body becomes physically and psychologically dependent on nicotine. Studies have shown that smokers must overcome both of these to be successful at quitting and staying quit.

When smoke is inhaled, nicotine is carried deep into the lungs, where it is absorbed quickly into the bloodstream and carried throughout the body. Nicotine affects many parts of the body, including your heart and blood vessels, your hormonal system, your metabolism, and your brain. Nicotine can be found in breast milk and in cervix mucous secretions of smokers. During pregnancy, nicotine freely crosses the placenta and has been found in amniotic fluid and the umbilical cord blood of newborn infants.

Several different factors can affect the rate of metabolism and excretion of nicotine. In general, a regular smoker will have nicotine or its by-products present in the body for about 3 to 4 days after stopping.

Nicotine produces pleasurable feelings that make the smoker want to smoke more. It also acts as a kind of depressant by interfering with the flow of information between nerve cells. As the nervous system adapts to nicotine, smokers tend to increase the number of cigarettes they smoke, and hence the amount of nicotine in their blood. After a while, the smoker develops a tolerance to the drug, which leads to an increase in smoking over time. Eventually, the smoker reaches a certain nicotine level and then smokes to maintain this level of nicotine.

Nicotine Withdrawal

When smokers try to cut back or quit, the absence of nicotine leads to withdrawal symptoms. Withdrawal is both physical and mental. Physically, the body is reacting to the absence of nicotine. Psychologically, the smoker is faced with giving up a habit, which is a major change in behavior. Both must be dealt with if quitting is to be successful.
Withdrawal symptoms can include any of the following:

  • dizziness (may only last 1-2 days in the beginning)
    depression
    feelings of frustration and anger
    irritability
    trouble sleeping
    trouble concentrating
    restlessness
    headache
    tiredness
    increased appetite


These symptoms can lead the smoker to again start smoking cigarettes to boost blood levels of nicotine back to a level where there are no symptoms.
If a person has smoked regularly for a few weeks or longer and abruptly stops using tobacco or greatly reduces the amount smoked, withdrawal symptoms will occur. Symptoms usually start within a few hours of the last cigarette and peak about 2 to 3 days later. Withdrawal symptoms can last for a few days to several weeks. For information on coping with withdrawal, see the section, "How to Quit."

Why Quit?
Your Health
Health concerns usually top the list of reasons people give for quitting smoking. About half of all smokers who continue to smoke will end up dying from a smoking-related illness. Nearly everyone knows that smoking can cause lung cancer, but few people realize it is also a risk factor for many other kinds of cancer as well, including cancer of the mouth, voice box (larynx), throat (pharynx), esophagus, bladder, kidney, pancreas, cervix, stomach, and some leukemias.
Smoking increases the risk of lung diseases such as emphysema and chronic bronchitis. These progressive lung diseases – grouped under the term COPD (chronic obstructive pulmonary disease) – are usually diagnosed in current or former smokers in their 60s and 70s. COPD causes chronic illness and disability and is eventually fatal.


Smokers are twice as likely to die from heart attacks as are nonsmokers. And smoking is a major risk factor for peripheral vascular disease, a narrowing of the blood vessels that carry blood to the leg and arm muscles, as well as cerebrovascular disease that can cause strokes.
Smoking also causes premature wrinkling of the skin, bad breath, bad smelling clothes and hair, and yellow fingernails and hair, yellow fingernails and increased risk of macular degeneration, one of the most common causes of blindness in the elderly.

For women, there are unique risks. Women over 35 who smoke and use birth control pills are in a high-risk group for heart attack, stroke, and blood clots of the legs. Women who smoke are more likely to have a miscarriage or a lower birth-weight baby. Low birth-weight babies are more likely to die or to be permanently impaired.

Based on data collected in the late 1990s, the US Centers for Disease Control (CDC) estimated that adult male smokers lost an average of 13.2 years of life and female smokers lost 14.5 years of life because of smoking.

No matter what your age or how long you've smoked, quitting will help you live longer. People who stop smoking before age 35 avoid 90% of the health risks attributable to tobacco. Even those who quit later in life can significantly reduce their risk of dying at a younger age.
Ex-smokers also enjoy a higher quality of life with fewer illnesses from cold and flu viruses, better self-reported health status, and reduced rates of bronchitis and pneumonia.
For decades the Surgeon General has reported the health risks associated with smoking. Regardless of your age or smoking history, there are advantages to quitting smoking. Benefits apply whether you are healthy or you already have smoking-related diseases. In 1990, the Surgeon General concluded:

Quitting smoking has major and immediate health benefits for men and women of all ages. Benefits apply to people with and without smoking-related disease.
Former smokers live longer than continuing smokers. For example, people who quit smoking before age 50 have one-half the risk of dying in the next 15 years compared with continuing smokers.
Quitting smoking decreases the risk of lung cancer, other cancers, heart attack, stroke, and chronic lung disease.
Women who stop smoking before pregnancy or during the first 3 to 4 months of pregnancy reduce their risk of having a low birth weight baby to that of women who never smoked.
The health benefits of quitting smoking far exceed any risks from the average 5-pound weight gain or any adverse psychological effects that may follow quitting.

When Smokers Quit – What Are the Benefits Over Time?
20 minutes after quitting: Your heart rate drops. (US Surgeon General's Report, 1988, pp. 39, 202)
12 hours after quitting: The carbon monoxide level in your blood drops to normal. (US Surgeon General's Report, 1988, p. 202)
2 weeks to 3 months after quitting: Your circulation improves and your lung function increases. (US Surgeon General's Report, 1990, pp.193,194,196,285,323)
1 to 9 months after quitting: Coughing and shortness of breath decrease; cilia (tiny hair like structures that move mucus out of the lungs) regain normal function in the lungs, increasing the ability to handle mucus, clean the lungs, and reduce the risk of infection. (US Surgeon General's Report, 1990, pp. 285-287, 304)
1 year after quitting: The excess risk of coronary heart disease is half that of a smoker's. (US Surgeon General's Report, 1990, p. vi)
5 years after quitting: Your stroke risk is reduced to that of a nonsmoker 5-15 years after quitting. (US Surgeon General's Report, 1990, p. vi)
10 years after quitting: The lung cancer death rate is about half that of a continuing smoker's. The risk of cancer of the mouth, throat, esophagus, bladder, cervix, and pancreas decrease. (US Surgeon General's Report, 1990, pp. vi, 131, 148, 152, 155, 164,166)
15 years after quitting: The risk of coronary heart disease is that of a nonsmoker's. (US Surgeon General's Report, 1990, p. vi)
Visible and Immediate Rewards of Quitting
Quitting helps stop the damaging effects of tobacco on your appearance including:
premature wrinkling of the skin
bad breath
stained teeth
gum disease
bad smelling clothes and hair
yellow fingernails
Kicking the tobacco habit also offers benefits that you'll notice immediately and some that will develop gradually in the first few weeks. These rewards can improve your day-to-day life substantially:
Food tastes better.
Sense of smell returns to normal
Ordinary activities no longer leave you out of breath (climbing stairs, light housework, etcetera.)
The prospect of better health is a major reason for quitting, but there are others as well.
Cost
Smoking is expensive. It isn't hard to figure out how much you spend on smoking: multiply how much money you spend on tobacco every day by 365 (days per year). The amount may surprise you. Now multiply that by the number of years you have been using tobacco and that amount will probably astound you.
Multiply the cost per year by 10 (for the upcoming 10 years) and ask yourself what you would rather do with that much money.
And this doesn’t include other possible expenses, such as higher costs for health and life insurance, as well as the health care costs due to tobacco-related conditions.
Social Acceptance
Smoking is less socially acceptable now than it was in the past.
Most workplaces have some type of smoking restrictions. Some employers even prefer to hire nonsmokers. Studies show smoking employees cost businesses more to employ because they are "out sick" more frequently. Employees who are ill more often than others can raise an employer’s need for expensive temporary replacement workers. They can increase insurance costs both for other employees and for the employer, who typically pays part of the workers’ insurance premiums. Smokers in a building also typically increase the maintenance costs of keeping odors at an acceptable level, since residue from cigarette smoke clings to carpets, drapes, and other fabrics.
Landlords, also, may choose not to rent to smokers since maintenance costs and insurance rates may rise when smokers occupy buildings.
Friends may ask you not to smoke in their houses or cars. Public buildings, concerts, and even sporting events are largely smoke-free. And more and more communities are restricting smoking in all public places, including restaurants and bars. Like it or not, finding a place to smoke can be a hassle.
Smokers may find their opportunities for dating or romantic involvement, including marriage, are largely limited to other smokers, who make up only about 1/4th of the population.
Health of Others
Smoking not only harms your health but the health of those around you. Exposure to secondhand smoke (also called environmental tobacco smoke or passive smoking) includes exhaled smoke as well as smoke from burning cigarettes.
Studies have shown that secondhand smoke causes thousands of deaths each year from lung cancer and heart disease in healthy nonsmokers.
Smoking by mothers is linked to a higher risk of their babies developing asthma in childhood, especially if the mother smokes while pregnant. It is also associated with sudden infant death syndrome (SIDS) and low-birth weight infants. Babies and children raised in a household where there is smoking have more ear infections, colds, bronchitis, and other respiratory problems than children from nonsmoking families. Secondhand smoke can also cause eye irritation, headaches, nausea, and dizziness.
Setting an Example
If you have children, you probably want to set a good example for them. When asked, nearly all smokers say they don't want their children to smoke, but children whose parents smoke are more likely to start smoking themselves. You can become a good role model for them by quitting now.
Help Is Available
With the wide array of counseling services, self-help materials, and medicines available today, smokers have more tools than ever before to help them quit successfully.
Remember, tobacco addiction has both a psychological and a physical component. For most people, the best way to quit will be some combination of medicine, a method to change personal habits, and emotional support. The following sections describe these tools and how they may be helpful for you.

Help With Psychological Addiction
Some people are able to quit on their own, without the help of others or the use of medicines. But for many smokers, it can be hard to break the social and emotional ties to smoking while getting over nicotine withdrawal symptoms at the same time. Fortunately, there are many sources of support out there – both formal and informal.
Telephone-based Help to Stop Smoking
Most states run some type of free telephone-based program that links callers with trained counselors, such as the American Cancer Society’s Quitline program. These specialists help plan a quit method that fits each person's unique smoking pattern. People who use telephone counseling stop smoking at twice the rate of those who don't get this type of help. With guidance from a counselor, quitters can avoid common mistakes that may hurt a quit attempt.
Telephone counseling is also more convenient for many people than some other support programs. It doesn't require transportation or childcare, and it's available nights and weekends. Counselors may recommend a combination of methods including medicines, local classes, self-help brochures, and/or a network of family and friends.
Smokers can get help finding a Quitline program in their area by calling ACS at 1-800-ACS-2345 (1-800-227-2345).
Support of Family, Friends, and Quit Programs
Many former smokers say a support network of family and friends was very important during their quit attempt. Other people who may offer support and encouragement are coworkers, your family doctor, and members of support groups for quitters. You can check with your employer, health insurance company, or local hospital to find support groups; or call the ACS at 1-800-ACS-2345.
What to Look for in a Stop-Smoking Program
Stop smoking programs are designed to help smokers recognize and cope with problems that come up during quitting and to provide support and encouragement in staying quit. Studies have shown that the best programs will include either individual or group counseling. There is a strong association between the intensity of counseling and the success rate. In general, the more intense the program, the greater the likelihood of success.
Intensity may be increased by having more or longer sessions or by increasing the number of weeks over which the sessions are given. So, when considering a program, look for one that has the following:
session length – at least 20 to 30 minutes per session
number of sessions – at least 4 to 7 sessions
number of weeks – at least 2 weeks
Be certain the leader of the group has training in smoking cessation.
Some communities have a Nicotine Anonymous group that holds regular meetings. This group applies the principles of Alcoholics Anonymous to the addiction of smoking. There is no fee to attend.
Often your local American Cancer Society, American Lung Association, or local health department will sponsor quit smoking classes. Call 1-800-ACS-2345 for more information.
There are some programs to watch out for as well. Not all programs are ethical. Be very careful of programs that do the following:
Promise instant, easy success with no effort on your part.
Use injections or pills, especially "secret" ingredients (nicotine replacement is covered elsewhere).
Charge a very high fee. Check with the Better Business Bureau if you have doubts.
Are not willing to provide references from people who have taken the class.
Help With Physical Addiction: Nicotine Replacement Therapy and Other Medicines
Nicotine Replacement Therapy
As mentioned earlier, the nicotine in cigarettes leads to actual physical dependence, which can cause unpleasant symptoms when a person tries to quit. Nicotine replacement therapy (NRT) provides nicotine – in the form of gums, patches, sprays, inhalers or lozenges – without the other harmful components of tobacco. It can help relieve some of these symptoms so that a person can concentrate more on the psychological aspects of quitting.
How Nicotine Replacement Works
Nicotine substitutes treat the very difficult withdrawal symptoms and cravings that 70% to 90% of smokers say is their only reason for not giving up cigarettes. By using a nicotine substitute, a smoker's withdrawal symptoms are reduced.
While a large number of smokers are able to quit smoking without nicotine replacement, most of those who attempt quitting are not successful on the first try. In fact, smokers usually need several attempts – sometimes as many as 8 to 10 – before they are able to quit for good.
Lack of success is often related to the onset of withdrawal symptoms. By reducing these symptoms with the use of nicotine replacement therapy, smokers who want to quit have a better chance of being successful.
Getting the Most From Nicotine Replacement
Nicotine replacement therapy only deals with the physical aspects of addiction. It is not intended to be the only method used to help you quit smoking. It should be combined with other smoking cessation methods that address the psychological component of smoking, such as a stop smoking program. Studies have shown that approach - pairing NRT with a program that helps to change behavior – can double your chances of successfully quitting.
The US Agency for Healthcare Research and Quality (AHRQ) Clinical Practice Guideline on Smoking Cessation recommends NRT for all smokers except pregnant women and people with heart or circulatory diseases. If a health care provider suggests nicotine replacement for people in these groups, the benefits of smoking cessation must outweigh the potential health risk. Smokers who are pregnant or have heart disease should consult with their doctor before using over-the-counter nicotine replacement.
The most effective time to start NRT is at the beginning of an attempt to quit. But often smokers first try to quit on their own, then decide to try NRT.
Nicotine replacement therapy should not be used if you plan to continue to smoke or use another tobacco product. The combined dose of nicotine could be dangerous to your health.
Types of Nicotine Substitutes
Five types of nicotine replacement therapy have been approved for use by the US Food and Drug Administration (FDA).
Nicotine patches (transdermal nicotine systems): Patches provide a measured dose of nicotine through the skin. As the nicotine doses are lowered by switching patches over a course of weeks, the tobacco user is weaned off nicotine. Patches can be purchased without a prescription. Several types and different strengths are available. Package inserts describe how to use the product as well as special considerations and possible side effects.
The 16-hour patch works well for light-to-average tobacco users. It is less likely to cause side effects like skin irritation, racing heartbeat, sleep problems, and headache. But it does not deliver nicotine during the night, so it is not helpful for early morning withdrawal symptoms.
The 24-hour patch provides a steady dose of nicotine, avoiding peaks and troughs. It helps with early morning withdrawal. However, there may be more side effects such as disrupted sleep patterns and skin irritation.
Depending on body size, most tobacco users should start using a full-strength patch (15-22 mg of nicotine) daily for 4 weeks, and then use a weaker patch (5-14 mg of nicotine) for another 4 weeks. The patch should be applied in the morning to a clean, dry area of the skin without much hair. It should be placed below the neck and above the waist - for example, on the arm. The FDA recommends using the patch for a total of 3 to 5 months. However, some studies have shown that using it for 8 weeks or less is just as effective as using it for longer.
Side effects are related to:
the dose of nicotine
the brand of patch
your individual skin characteristics (such as the person’s tendency to have a skin reaction to the patch)
how long you use the patch
how it is applied
Some possible side effects of the nicotine patch include:
skin irritation – redness and itching
dizziness
racing heartbeat
sleep problems or unusual dreams
headache
nausea
vomiting
muscle aches and stiffness
What to do about side effects:
Try a different brand of patch if skin irritation occurs.
Reduce the amount of nicotine by using a lower dose patch.
Sleep problems may be temporary and pass within 3 or 4 days. If not (and you're using a 24-hour patch), try switching to a 16-hour patch.
Stop using the patch and try a different form of nicotine replacement.
Nicotine gum (nicotine polacrilex): Nicotine gum is a fast-acting form of replacement that acts through the mucous membrane of the mouth. It can be bought over-the-counter without a prescription. It comes in 2 mg and 4 mg strengths.
For best results, follow the instructions of the package insert. Chew the gum slowly until you note a peppery taste. Then, "park" it against the cheek, chewing it and parking it off and on for about 20 to 30 minutes. Food and drink can affect how well the nicotine is absorbed. You should avoid acidic foods and drinks such as coffee, juices, and soft drinks for at least 15 minutes before and during gum use.
If you smoke a pack or more per day, smoke within 30 minutes of rising, or have trouble not smoking in restricted areas, you may need to start with the higher dose (4 mg). No more than 20 pieces should be used in one day. Nicotine gum is usually recommended for 1 to 3 months, with the maximum being 6 months. Tapering the amount of gum chewed may help you stop using it.
If you have sensitive skin, you may prefer the gum to the patch. Another advantage of nicotine gum is that it allows you to control the nicotine doses. The gum can be chewed as needed or on a fixed schedule during the day. The most recent data have shown that scheduled dosing is more effective. A schedule of 1 to 2 pieces per hour is common. On the other hand, with an as-needed schedule, you can chew more gum during a craving.
Some possible side effects of the gum:
bad taste
throat irritation
mouth sores
hiccups
nausea
jaw discomfort
racing heartbeat
Symptoms related to the stomach and jaw are usually caused by improper use of the gum, such as swallowing nicotine or chewing too rapidly. The gum can also cause damage to dentures and dental prostheses.
Long-term dependence is one possible disadvantage of nicotine gum. In fact, research has shown that 15% to 20% of gum users who successfully quit smoking continue using the gum for a year or longer. Although the maximum recommended length of use is 6 months, continuing to use the gum is likely to be safer than going back to smoking. But since there is little research on the health effects of long-term nicotine gum use, most health care providers still recommend limiting its use to 6 months.
Nicotine nasal spray: The nasal spray delivers nicotine quickly to the bloodstream as it is absorbed through the nose. It is available only by prescription.
The nasal spray immediately relieves withdrawal symptoms and offers you a sense of control over nicotine cravings. Because it is easy to use, smokers report great satisfaction. However, the FDA cautions that since this product contains nicotine, it can be addictive. It recommends the spray be prescribed for 3-month periods and should not be used for longer than 6 months.
The most common side effects last about 1 to 2 weeks and can include the following:
nasal irritation
runny nose
watery eyes
sneezing
throat irritation
coughing
There is also the danger of using more than is needed. If you have asthma, allergies, nasal polyps, or sinus problems, your doctor may suggest another form of nicotine replacement.
Nicotine inhalers: Introduced in 1998, inhalers are available only by prescription. The nicotine inhaler is a plastic tube with a nicotine cartridge inside. When you puff on the inhaler, the cartridge provides a nicotine vapor. Unlike other inhalers, which deliver most of the medication to the lungs, the nicotine inhaler delivers most of the nicotine vapor to the mouth. In terms of similar behavior, nicotine inhalers are the closest thing to smoking a cigarette, which some smokers find helpful.
The recommended dose is between 6 and 16 cartridges a day, for up to 6 months.
The most common side effects, especially when first using the inhaler, include:
coughing
throat irritation
upset stomach
At this time, inhalers are the most expensive of the forms of NRT available.
Nicotine lozenges: These are the newest form of NRT on the market. The FDA recently approved the first nicotine-containing lozenge as an over-the-counter aid in smoking cessation. As with nicotine gum, the Commit lozenge is available in 2 strengths: 2 mg and 4 mg. Smokers determine which dose is appropriate based on how long after waking up they normally have their first cigarette.
The lozenge manufacturer recommends using it as part of a 12-week program. The recommended dose is one lozenge every 1-2 hours for 6 weeks, then one lozenge every 2-4 hours for weeks 7 to 9, and finally, one lozenge every 4-8 hours for weeks 10 to 12. In addition, the manufacturer recommends the following:
Stop all tobacco use when beginning therapy with the lozenge.
Do not eat or drink for 15 minutes before using the lozenge. (Some beverages can reduce the effectiveness of the lozenge).
Suck on the lozenge until it dissolves. Do not bite or chew it like a hard candy, and do not swallow it.
Do not use more than 5 lozenges in 6 hours, or more than 20 lozenges total per day.
Stop using the lozenge after 12 weeks. If you still feel you need to use the lozenge, talk to your doctor.
Do not use the lozenge if you continue to smoke, chew tobacco, use snuff or any other product containing nicotine (e.g., nicotine patch or gum).
Possible side effects of the nicotine lozenge include:
trouble sleeping
nausea
hiccups
coughing
heartburn
headache
flatulence (gas)
Which Type of Nicotine Replacement May Be Right for You?
There’s no evidence that any type of nicotine replacement therapy is significantly better than any other. When choosing which type of nicotine replacement you will use, think about which method will best fit your lifestyle and pattern of smoking. Do you want/need something to chew or occupy your hands? Or are you looking for once-a-day convenience?
Some important points to consider:
Nicotine gums, lozenges, and inhalers are oral substitutes that allow you to control your dosage to help keep cravings under better control.
Nicotine nasal spray works very quickly when you need it.
Nicotine inhalers allow you to mimic the use of cigarettes by puffing and holding the inhaler.
Nicotine patches are convenient and only have to be applied once a day.
Both inhalers and nasal sprays require a doctor’s prescription.
Some people may not be able to use patches, inhalers, or nasal sprays due to allergies or other conditions.
Combination of the patch and other nicotine replacement products: Using the nicotine patch along with shorter-acting products such as the gum, lozenge, nasal spray, or inhaler is another method of nicotine replacement therapy. The idea is to provide a steady dose of nicotine with the patch and to use one of the shorter-acting products when strong cravings arise. The few studies that have been done on combination NRT have found that it may be slightly better than a single product, but more research is needed to prove this and to find safe and effective doses. The combined use of nicotine replacement products has not yet been approved by the FDA. If you are considering using more than one nicotine replacement product, be sure to discuss this with your doctor first.Bupropion (Zyban)Bupropion (Zyban) is a prescription antidepressant in an extended-release form that reduces symptoms of nicotine withdrawal. It does not contain nicotine. This drug affects chemicals in the brain that are related to nicotine craving. It can be used alone or together with nicotine replacement. The usual dosage is one or two 150 mg tablets per day. This medication should not be taken if you have a history of seizures, anorexia, heavy alcohol use, or head trauma. Some doctors may recommend combination drug therapy for heavily addicted smokers, such as using bupropion along with a nicotine replacement patch and/or a short acting from of nicotine replacement (such as gum or lozenges).Varenicline (Chantix) Varenicline (Chantix) is a newer medicine developed specifically to help people stop smoking. It works by interfering with nicotine receptors in the brain, which has two effects. It lessens the pleasurable physical effects a person gets from smoking, as well as reducing the symptoms of nicotine withdrawal.Several studies have shown varenicline can more than double the chances of quitting smoking. Some studies have also found it may be more effective than bupropion, at least in the short term. Reported side effects of varenicline have included headaches, nausea, vomiting, trouble sleeping, unusual dreams, flatulence (gas), and changes in taste.
Other Methods of Quitting Other tools may also help some people, although there is no strong evidence they can improve your chances of quitting.Atropine and scopolamine combination therapy: Some smoking cessation clinics offer a program using shots of the anticholinergic drugs atropine and scopolamine to help reduce nicotine withdrawal symptoms. These drugs are more commonly prescribed for other reasons, such as digestive system problems, motion sickness, or Parkinson’s disease. The treatment usually involves shots given in the clinic on one day, followed by a few weeks of pills and wearing patches behind the ear. It may include other drugs to help with side effects as well.Possible side effects of this treatment can include dizziness, constipation, dry mouth, an altered sense of taste and smell, problems urinating, and blurry vision. People who are pregnant or have a history of heart problems, glaucoma, or uncontrolled high blood pressure are not allowed to participate in these programs. Some clinics claim high success rates, but there is no published scientific research to back up these claims. Both atropine and scopolamine are FDA approved for other uses, but they have not been formally studied or approved for help in quitting smoking. Before considering such a program, you may want to ask the clinic about long-term success rates (up to a year). Because these medicines are directed only at the physical aspect of quitting, you may also want to ask if the program includes counseling or other methods aimed at the psychological aspects of quitting.
Hypnosis might be useful for some people. Ask your doctor if he or she can recommend a good hypnotist if you are interested in this.
Acupuncture has been used for quitting smoking, but there is little evidence to support its effectiveness. Acupuncture, when it is done, is typically done on the ears on particular ear sites. Although there is a very weak suggestion that acupuncture might lower the desire for smoking, there still is no solid evidence that it is truly effective as a smoking cessation tool (see ACS document on Acupuncture.) For a list of local physician acupuncturists, contact the American Academy of Medical Acupuncture at 1-800-521-2262.
Low level laser therapy, also called cold laser therapy, is a related technique. Cold lasers are sometimes used for acupuncture, with laser beams to stimulate the body's acupoints rather than needles. The treatment is supposed to relax the smoker and release endorphins (naturally-occurring pain relief substances) in the body to simulate the effects of nicotine in the brain, or balance the body’s energy to relieve the addiction. Despite claims of success by some cold laser therapy providers, there is no scientific evidence that shows this is an effective method of helping people stop smoking (see ACS document on Cold Laser Therapy.)
Filters that reduce tar and nicotine in cigarettes are generally not effective since studies show that smokers who use filters actually tend to smoke more.
Smoking deterrents such as over-the-counter products that change the taste of tobacco, "stop smoking diets" that curb nicotine cravings, and combinations of vitamins have little scientific evidence to support their claims.
The same is true of “homeopathic” aids and herbal supplements. Because they are marketed as dietary supplements (as opposed to drugs), they don’t need FDA approval to be sold. The manufacturers don’t have to prove they’re effective, or even safe. Be sure to look closely at the product label of any product claiming it can help you stop smoking. No dietary supplement has been proven effective in helping people quit smoking. Some of these supplements have no nicotine in them, but have multiple combinations of herbal preparations. They too have no proven track record of helping people to stop smoking. Other Nicotine/Tobacco Products, Not Reviewed or Approved by the FDATobacco lozenges and pouches: Lozenges containing tobacco, (Arival, Interval) and small, tobacco-containing pouches (Revel, Exalt) are being marketed as alternative ways for smokers to get nicotine in places where smoking is not permitted, rather than as quit smoking aids. The FDA has ruled that these are types of smokeless tobacco, not smoking cessation aids; therefore, the FDA does not have authority over them. There is no evidence that these products can help a person quit smoking.Nicotine lollipops and lip balms: In the past, some pharmacies made a product called a "nicotine lollipop". These lollipops often contained a product called nicotine salicylate with a sugar sweetener. Nicotine salicylate is not approved for pharmacy use by the FDA. The FDA has warned several pharmacies to stop selling nicotine lollipops and lip balm on the Internet, calling the products "illegal." The FDA also said "the candy-like products present a risk of accidental use by children."Other similar smoking cessation products may not use nicotine salicylate, and therefore may be legal. However, they still pose a risk for children if they are not sufficiently labeled and stored safely.Nicotine water and nicotine wafers: These products have been sold in recent years as ways to get nicotine in places where smoking is not permitted. They are not marketed as aids to quitting smoking, but questions about their safety and legality have been raised.
A Word About Quitting Success Rates
Before you start using nicotine replacement or sign up for a stop smoking class or program, you may wonder what its success rate is. That's a hard question to answer for several reasons. First, not all programs define success in the same way. Does success mean that a person is not smoking at the end of the program? After 3 months, 6 months, or 1 year? If a program you're considering claims a certain success rate, ask for more details on how success is defined and what kind of follow-up is done to verify the rate.
The truth is, quit smoking programs, like other programs that treat addictions, often have a fairly low success rate. But that does not mean they are not worthwhile or that you should be discouraged. Your own success in quitting is what really counts, and that is under your control. About 5% to 16% of people are able to quit smoking for at least 6 months without any medicine to help with withdrawal. Several articles in medical journals have reported that between about 25% and about 33% of smokers who use medicines can remain smoke-free for over 6 months. There is early evidence that combining some medicines may be more effective than using them alone. Behavioral and supportive therapies may increase success rates even further. Check the package insert of any product you are using to see if the manufacturer provides free telephone-based counseling.
How to Quit
Smokers often say, "Don't tell me why to quit, tell me how." There is no one right way to quit, but there are some key elements in quitting smoking successfully. These 4 factors are crucial:
making the decision to quit
setting a quit date and choosing a quit plan
dealing with withdrawal
staying quit (maintenance)
Making the Decision to Quit
The decision to quit tobacco use is one that only you can make. Others may want you to quit, but the real commitment must come from you.
Researchers have looked into how and why people stop tobacco use. They have some ideas, or models, of how this happens.
The Health Belief Model says that you will be more likely to stop tobacco use if you:
believe that you could get a tobacco-related disease and this worries you
believe that you can make an honest attempt at quitting
believe that the benefits of quitting outweigh the benefits of continuing tobacco use
know of someone who has had health problems as a result of their tobacco use
Does any of these apply to you?
The Stages of Change Model identifies the stages that you go through when you make a change in behavior. Here are the stages as they apply to quitting tobacco use:
Pre-contemplation: At this stage, the tobacco user is not thinking seriously about quitting right now.
Contemplation: The tobacco user is actively thinking about quitting but is not quite ready to make a serious attempt yet. This person may say, "Yes, I'm ready to quit, but the stress at work is too much, or I don't want to gain weight, or I'm not sure if I can do it."
Preparation: Tobacco users in the preparation stage seriously intend to quit in the next month and often have tried to quit in the past 12 months. They usually have a plan.
Action: This is the first 6 months when the user is actively quitting.
Maintenance: This is the period of 6 months to 5 years after quitting when the ex-user is aware of the danger of relapse and take steps to avoid it.
Where do you fit in this model? If you are thinking about quitting, setting a date and deciding on a plan will move you into the preparation stage, the best place to start.
Setting a Quit Date and Deciding on a Plan
Once you've made a decision to quit, you're ready to pick a quit date. This is a very important step. Pick a specific day within the next month as your "Quit Day." Picking a date too far in the future allows you time to rationalize and change your mind. But do give yourself enough time to prepare and come up with a plan. You might choose a date that has a special meaning like a birthday or anniversary, or the date of the Great American Smokeout (third Thursday in November each year). Or you may want to simply pick a random date. Circle the date on your calendar. Make a strong, personal commitment to quit on that day.
There is no one right way to quit. Most tobacco users prefer to quit "cold turkey" – that is, abruptly and totally. They use tobacco until their Quit Day and then stop all at once, or they may cut down on tobacco for a week or 2 before their Quit Day. Another way involves cutting down on the number of times tobacco is used each day. With this method, you gradually reduce the amount of nicotine in your body. While it sounds logical to cut down in order to quit gradually, in practice this method is difficult.
Quitting tobacco is a lot like losing weight; it takes a strong commitment over a long period of time. Users may wish there was a magic bullet – a pill or method that would make quitting painless and easy. But that is not the case. Nicotine substitutes can help reduce withdrawal symptoms, but they are most effective when used as part of a stop tobacco use plan that addresses both the physical and psychological components of quitting.
Here are some steps to help you prepare for your Quit Day:
Pick the date and mark it on your calendar.
Tell friends and family about your Quit Day.
Stock up on oral substitutes – sugarless gum, carrot sticks, and/or hard candy.
Decide on a plan. Will you use NRT or other medications? Will you attend a class? If so, sign up now.
Practice saying, "No thank you, I don't smoke."
Set up a support system. This could be a group class, Nicotine Anonymous, or a friend or family member who has successfully quit and is willing to help you.
Successful quitting is a matter of planning and commitment, not luck. Decide now on your own plan. Some possibilities include using the nicotine patch or gum, joining a tobacco cessation class, going to Nicotine Anonymous meetings, or using self-help materials such as books and pamphlets. For the best chance at success, your plan should include one or more of these options.
On your Quit Day, follow these suggestions:
Do not smoke.
Get rid of all cigarettes, lighters, ashtrays, and any other items related to smoking.
Keep active – try walking, exercising, or doing other activities or hobbies.
Drink lots of water and juices.
Begin using nicotine replacement if that is your choice.
Attend stop smoking class or start following a self-help plan.
Avoid situations where the urge to smoke is strong.
Reduce or avoid alcohol.
Dealing With Withdrawal
Withdrawal from nicotine has 2 parts – the physical and the psychological. The physical symptoms, while annoying, are not life threatening. Nicotine replacement can help reduce many of these physical symptoms. But most users find that the bigger challenge is the mental part of quitting.
If you have been smoking for any length of time, smoking has become linked with nearly everything you do – waking up in the morning, eating, reading, watching TV, drinking coffee, etc. It will take time to "un-link" smoking from these activities. That is why, even if you are using a nicotine replacement, you may still have strong urges to smoke.
One way to overcome these urges or cravings is to recognize rationalizations as they come up. A rationalization is a mistaken belief that seems to make sense at the time but is not based on facts. If you have tried to quit before, you will probably recognize many of these common rationalizations.
I’ll just use it to get through this rough spot.
Today is not a good day; I’ll quit tomorrow.
It's my only vice.
How bad is tobacco, really? Uncle Harry chewed all his life and he lived to be over 90.
You've got to die of something.
Life is no fun without smoking.
You probably can add more to the list. As you go through the first few days without tobacco, write down any rationalizations as they come up and recognize them for what they are: messages that can trap you into going back to using tobacco. Use the ideas below to help you keep your commitment to quitting.
Avoid people and places where you are tempted to smoke. Later on you will be able to handle these with more confidence.
Alter your habits. Switch to juices or water instead of alcohol or coffee. Take a different route to work. Take a brisk walk instead of a coffee break.
Alternatives. Use oral substitutes such as sugarless gum or hard candy, raw vegetables such as carrot sticks, or sunflower seeds.
Activities. Exercise or do hobbies that keep your hands busy, such as needlework or woodworking, that can help distract you from the urge to smoke.
Deep breathing. When you were smoking, you breathed deeply as you inhaled the smoke. When the urge strikes now, breathe deeply and picture your lungs filling with fresh, clean air. Remind yourself of your reasons for quitting and the benefits you'll gain as an ex-smoker.
Delay. If you feel that you are about to light up, delay. Tell yourself you must wait at least 10 minutes. Often this simple trick will allow you to move beyond the strong urge to smoke.
What you're doing is not easy, so you deserve a reward. Put the money you would have spent on tobacco in a jar every day and then buy yourself a weekly treat. Buy a magazine, go out to eat, call a friend long-distance. Or save the money for a major purchase. You can also reward yourself in ways that don't cost money: take time out to read, work on a hobby, or take a relaxing bath.
Staying Quit (Maintenance)
Remember the quotation by Mark Twain? Maybe you, too, have quit many times before. So you know that staying quit is the final, and most important, stage of the process. You can use the same methods to stay quit as you did to help you through withdrawal. Think ahead to those times when you may be tempted to smoke, and plan on how you will use alternatives and activities to cope with these situations.
More dangerous, perhaps, are the unexpected strong desires to smoke that occur sometimes months (or even years) after you've quit. To get through these without relapse, try the following:
Review your reasons for quitting and think of all the benefits to your health, your finances and your family.
Remind yourself that there is no such thing as just one cigarette – or even one puff.
Ride out the desire. It will go away, but do not fool yourself into thinking you can have just one.
What if you do smoke? The difference between a slip and a relapse is within your control. You can use the slip as an excuse to go back to smoking, or you can look at what went wrong and renew your commitment to staying off smoking for good.
Even if you do relapse, try not to get too discouraged. Very few people are able to quit for good on the first attempt. In fact, it takes most people several attempts before quitting for good. What’s important is figuring out what helped you in your attempt to quit and what worked against you. You can then use this information to make a stronger attempt at quitting the next time.
Special Concerns
Weight Gain
Many smokers do gain some weight when they quit. Even without special attempts at diet and exercise, however, the gain is usually less than 10 pounds. Women tend to gain slightly more weight than men. There is some evidence that smokers will gain weight after they quit even if they do not eat more.
For some, a concern about weight gain can lead to a decision not to quit. But the weight gain that follows quitting smoking is generally very small. It is much more dangerous to continue smoking than it is to gain a small amount of weight.
You are more likely to be successful with quitting smoking if you deal with the smoking first, and then later take steps to reduce your weight. While you are quitting, try to focus on ways to help you stay healthy, rather than on your weight. Stressing about your weight may make it harder to quit. Eat plenty of fruits and vegetables and limit the fat. Be sure to drink plenty of water, and get enough sleep and regular physical activity.
Walking is a great way to be physically active and increase your chances of staying quit. Walking can help you by:
reducing stress
burning calories and toning muscles
giving you something to do instead of thinking about smoking
No special equipment or clothing is needed for walking, other than a pair of comfortable shoes. And you can do it pretty much anytime or anywhere. Try the following:
walking around a shopping mall
getting off the bus one stop before you usually do
finding a buddy to walk with during lunch time at work
taking the stairs instead of the elevator
walking with a friend, family member, or neighbor after dinner
pushing your baby in a stroller
Set a goal of 30 minutes of physical activity 5 or more times a week. If you don’t already exercise regularly, please check with your doctor before starting an exercise program.
Stress
Smokers often mention stress as one of the reasons for going back to smoking. Stress is a part of all of our lives, smokers and nonsmokers alike. The difference is that smokers have come to use nicotine to help cope with stress. When quitting, you have to learn new ways of handling stress. Nicotine replacement can help to some extent, but for long-term success other strategies are needed.
As mentioned above, physical activity is a good stress-reducer. It can also help with the temporary sense of depression that some smokers experience when they quit. There are also stress-management classes and self-help books. Check your community newspaper, library, or bookstore.
Spiritual practices such as prayer and meditation have been used very successfully with other addictions and are an integral part of 12-step recovery programs. These same principles can be applied to quitting smoking and can help with stress reduction.
Where Can I Go for Help?
It is hard to stop smoking. But if you are a tobacco user you can quit! More than 46 million Americans have quit smoking for good. Many organizations offer information, counseling, and other services on how to quit as well as information on where to go for help. Other good resources where help can be found include your doctor, dentist, local hospital, or employer.
If you want to quit smoking and need help, contact one of the following organizations.
