Smoking has serious long-term consequences, including the risk of smoking-related diseases and premature death, as well as the increased health care costs associated with treating the illnesses.93 One of every six deaths in the United States is a result of tobacco use, making tobacco more lethal than all other addictive drugs combined. Nearly 90 percent of smokers start smoking by age 18, and of smokers under 18 years of age, more than 6 million will die prematurely from a smokingrelated disease.94 These consequences underscore the importance of studying patterns of smoking among adolescents.
