Abstract in brief

The review examines how age influences the effects of cannabis on brain function and cognition, particularly comparing adolescents and adults, and suggests that adolescents may experience greater impairments, especially in executive functioning, when using cannabis frequently.
The findings indicate that age-related differences might be strongest among heavy or dependent users, and that certain effects, like craving and inhibitory control, may not improve as much after intoxication in adolescents compared to adults.
The study also proposes that adolescents may be more vulnerable to learning deficits caused by cannabis, but these negative effects might not last after they stop using, which has implications for policy and prevention strategies.]
