Teens use of substances

Teens' use of substances has dropped in recent years. But substance use still remains a leading cause of injury and death in young people. It also causes long-term social and health problems. Growth and development can be affected by tobacco, alcohol, and drugs. Teens who abuse these substances may have trouble finding their identity, building relationship skills, and becoming emotionally stable. They also may have trouble preparing for their future. Substance abuse can affect memory and learning, which can harm a teen's schoolwork.
