Antecedents and consequences of marijuana use trajectories over the life course in an African American population.

ABSTRACT:

Background

We examined developmental trajectories of marijuana use among a cohort of urban African Americans followed from first grade to mid adulthood. We compared risk factors in childhood and adolescence and consequences in mid adulthood across trajectory groups.

Methods

Using semiparametric group-based mixture modeling, five marijuana trajectories for men (n=455) and four trajectories for women (n=495) were identified extending from adolescence to young adulthood (age 32). We labeled the four trajectory groups similar for men and women "abstainers," "adolescent only users," "early adulthood decliners," and "persistent users." We named the unique fifth group for men "late starters."

Results

Multivariate multinomial logistic regressions show that childhood problem b
