Summary:Highlights • Identified 7 latent marijuana use classes from ages 18-50 among a national sample. • Twenty-eight percent of respondents reported longer-term moderate/heavy use. • Use reduction appeared particularly likely during early and late young adulthood. • Key characteristics differentiated between use/non-use, use intensity and duration. • Adverse health outcome likelihood increased with use intensity and duration.
