Research linking early cannabis use to slower gains in these cognitive areas raises concerns because many teens who try cannabis show normal abilities at first, then stop improving at the rate their peers do. Evidence points to THC, the compound that produces psychoactive effects, as a likely factor in the pattern, with memory appearing particularly vulnerable. These findings matter for families, educators, and clinicians who want young people to reach their cognitive potential.
Curious about how researchers measured these developmental changes and what the results mean for prevention, recovery, and equitable support for young people? The full report explores the methods and implications, and offers clues about how timing, dose, and context influence outcomes for human potential and inclusive pathways to healthy adolescent development.
Teens who start using cannabis may experience slower growth in memory, attention, language, and processing speed. Their abilities often developed normally at first, then began leveling off while nonusers continued improving. THC appeared to be the most likely driver, especially for worsening memory.
