Most adult smokers begin smoking during adolescence. Quitting appears to be harder with each passing year of addiction, so efforts to increase smoking cessation among adolescents are critical. In this community-based sample of 4078 high school students, Klesges and colleagues report that 5% of adolescents overall and 40% of former smokers have used nicotine replacement therapy, either as gum or patches. Of concern, however, is that 18% of nicotine replacement users have never smoked, indicating inappropriate use of these products. The fact that half of adolescents report easy access to nicotine replacement therapies indicates the need for appropriate restrictions on their use and dissemination.
