Tobacco use can lead to tobacco/nicotine dependence and serious health problems. Quitting smoking greatly reduces the risk of developing smoking-related diseases.
Tobacco/nicotine dependence is a condition that often requires repeated treatments, but there are helpful treatments and resources for quitting.
- Most smokers become addicted to nicotine, a drug that is found naturally in tobacco.
- Quitting smoking is hard and may require several attempts. People who stop smoking often start again because of withdrawal symptoms, stress, and weight gain.
- Nicotine withdrawal symptoms may include:
- Feeling irritable, angry, or anxious
- Having trouble thinking
- Craving tobacco products
- Feeling hungrier than usual
Health Benefits of Quitting
Tobacco smoke contains a deadly mix of more than 7,000 chemicals; hundreds are harmful, and about 70 can cause cancer. Smoking increases the risk for serious health problems, many diseases, and death.
People who stop smoking greatly reduce their risk for disease and early death. Although the health benefits are greater for people who stop at earlier ages, there are benefits at any age. You are never too old to quit.
Stopping smoking is associated with the following health benefits:
- Lowered risk for lung cancer and many other types of cancer.
- Reduced risk for heart disease, stroke, and peripheral vascular disease (narrowing of the blood vessels outside your heart).
- Reduced heart disease risk within 1 to 2 years of quitting.
- Reduced respiratory symptoms, such as coughing, wheezing, and shortness of breath. While these symptoms may not disappear, they do not continue to progress at the same rate among people who quit compared with those who continue to smoke.
- Reduced risk of developing some lung diseases (such as chronic obstructive pulmonary disease, also known as COPD.
- Reduced risk for infertility in women of childbearing age. Women who stop smoking during pregnancy also reduce their risk of having a low birth weight baby.
Ways to Quit Smoking
The following treatments are proven to be effective for smokers who want help to quit:
- Brief help by a doctor (such as when a doctor takes 10 minutes or less to give a patient advice and assistance about quitting)
- Behavioral therapies (such as training in problem solving)
- Treatments with more person-to-person contact and more intensity (such as more or longer counseling sessions)
- Programs to deliver treatments using mobile phones
Medications for quitting that have been found to be effective include the following:
- Nicotine replacement products
- Over-the-counter (nicotine patch [which is also available by prescription], gum, lozenge)
- Prescription (nicotine patch, inhaler, nasal spray)
- Prescription non-nicotine medications: bupropion SR (Zyban®), varenicline tartrate (Chantix®)
Counseling and medication are both effective for treating tobacco dependence, and using them together is more effective than using either one alone.
