Implication

Analysis finds cannabis use linked to negative changes in psychopathology and functional well-being in young adults, indicating risks associated with frequent use.

Key Points

Frequent cannabis use predicted increases in psychotic-like experiences and internalizing symptoms between ages 20 and 24.
Cannabis use was assessed using both self-reported frequency and hair THC concentrations, with small effect sizes observed.
Regression models adjusted for sex, sociodemographic characteristics, and initial outcomes reported at age 20 demonstrated significant associations.
Findings highlight potential adverse effects of cannabis on mental health and functional well-being during young adulthood.
