Young people are far more likely than adults to greatly over-estimate the prevalence of smoking. Such programmes are even more successful when they are support in the adolescent's home and community. Strongly enforced laws that prohibit the sale of tobacco to young people. Policies in the school, workplace and community that restrict smoking. Most Americans strongly favour policies that might prevent tobacco use among youth.
Males are much more likely than females to use smokeless tobacco.
Over the past decade, there has been virtually no decline in smoking rates among all teens. Among black adolescents, however, the prevalence of smoking has declined dramatically. Most of these were males. Young people who come from a low-income family and have fewer than two adults living in their household are especially at risk for becoming smokers. When the minors tried to purchase cigarettes through vending machines, they were almost always successful.
