Harmful drinking among adolescents is a major concern in many countries. It reduces self-control and increases risky behaviours, such as unsafe sex or dangerous driving. It is a primary cause of injuries (including those due to road traffic accidents), violence (especially by a partner) and premature deaths. It can also lead to health problems in later life and affect life expectancy. Setting a minimum age for buying and consuming alcohol and regulating how alcoholic drinks are targeted at the younger market are among the strategies for reducing harmful drinking.
Drug use among 15–19 year olds is also an important global concern. Drug control may focus on reducing drug demand, drug supply, or both, and successful programmes usually include structural, community, and individual-level interventions.
Tobacco use
The vast majority of people using tobacco today began doing so when they were adolescents. Prohibiting the sale of tobacco products to minors and increasing the price of tobacco products through higher taxes, banning tobacco advertising and ensuring smoke-free environments are crucial. Globally, at least 1 in 10 adolescents aged 13 to 15 years uses tobacco, although there are areas where this figure is much higher. Cigarette smoking seems to be decreasing among younger adolescents in some high-income countries.
