Smoking rates in public schools have decreased significantly over the years due to increased awareness of health risks, less tobacco marketing, and lower commercialism. The percentage of smokers dropped from 36% in 1997 to 22% currently among high school and middle school students. Tobacco companies have also reduced cigarette advertisements. While smoking has declined, many students still obtain cigarettes from others or stores and half of high school smokers want to quit, showing the ongoing challenges of preventing youth smoking.
