The document discusses teen smoking and its health risks. It notes that tobacco use primarily begins during adolescence, with 1/3 of smokers starting before age 14. Smoking causes various cancers, heart and lung diseases, and is currently predicted to cause 6.4 million premature deaths among children who currently smoke. The teen mind is more susceptible to addiction due to an underdeveloped prefrontal cortex and a desire to fit in. Nicotine binds to the brain's reward system, reinforcing smoking behavior. Education, legislation, and social support can help prevent teen smoking.
