Typologies of illicit drug use in mid-adulthood: a quasi-longitudinal latent class analysis in a community-based sample of twins.

ABSTRACT:

Aims

To identify drug use typologies based on substances used and persistence of use over two time points, use a genetically informed design to explore twin concordance of and genetic influence on the use typologies and compare patterns of declined/discontinued ("desistant") and persistent drug use on drug use correlates.

Design

Latent class analysis was applied to data from a cross-sectional self-report survey on current and past drug use. Use characteristics, use disorder, and psychiatric problems were compared across classes.

Setting

Computer-assisted telephone interview in respondents' homes.

Participants

A total of 3785 individual twins and siblings (1365 men, 2420 women; M_age  = 32) from the Australian Twin Registry Cohort III.
