For Youth
Know the risks of youth marijuana use
Marijuana use directly affects the parts of the brain responsible for decision-making, emotions, coordination and reaction time. In adolescents, the brain is actively developing and will continue to develop until about age 25. Using marijuana during adolescence and early adulthood can harm the developing brain.

What are the short-term effects of marijuana on the brain?
Recent marijuana use (defined as within 24 hours) in youth and adults has an immediate impact on thinking, attention, memory, coordination, movement, and time perception.
What are the long-term effects of marijuana on the brain?
Using marijuana before age 18 may affect how the brain builds connections for functions like attention, memory, and learning. Marijuana’s effects on attention, memory, and learning may last a long time or even be permanent, but more research is needed to fully understand these effects. Youth who use marijuana may not do as well in school and may have trouble remembering things.

Marijuana and Mental Health
Regular marijuana use has been linked to depression, anxiety, and suicide in teens.
The teen years are a time of growth, exploration, and risk-taking. Some risk-taking may foster identity development and independence (e.g., running for student council, asking someone out on a date). However, some risk behaviors—such as using marijuana—can have adverse effects on a teen’s health and well-being.

Addiction Potential
About 3 of 10 people who use marijuana have marijuana use disorder. Some signs and symptoms of the disorder include trying to stop marijuana use but failing, or giving up important activities with friends and family in favor of using marijuana. The risk of developing marijuana use disorder is higher in people who start using it during youth or adolescence and who use it more frequently.
