Tobacco and lung cancer

Studies show that smoking tobacco products in any form is the major cause of lung cancer. People who stop smoking and never start again lower their risk of developing lung cancer or of having lung cancer recur (come back). Many products, such as nicotine gum, nicotine sprays, nicotine inhalers, nicotine patches, or nicotine lozenges, may be helpful to people trying to quit smoking, as well as antidepressant drugs. In addition, a number of efforts at the community, state, and national level have helped to reduce smoking rates.
