Illustration: Risk and Protective Factors for Youth Substance Use

The individual, family, school and community factors that raise or lower a young person's risk, and how prevention targets them.

No single cause explains why some young people develop problems with alcohol or drugs and others do not. Prevention science instead looks at risk factors, which raise the chances, and protective factors, which lower them. The more risk factors a young person has, and the fewer protective ones, the higher the likelihood of problems.

Common risk factors

Protective factors

Why this framework matters

Many risk factors for substance use are shared with other problems such as school dropout, delinquency and teen pregnancy. Community prevention systems such as Communities That Care survey local youth, identify which factors are most elevated, and choose tested programs to address them. Randomized trials of this approach have found lower rates of youth drinking, smoking and delinquency years later.

Genetics is not destiny

Family history raises risk, partly through genetics. It does not determine outcomes. Young people with a family history benefit from knowing it, the same way they would with a family history of heart disease, and from delaying or avoiding use.
