Adolescent cannabis use and repeated voluntary unprotected sex in women.

ABSTRACT:

Background and aims

Substance use has been implicated in the onset and maintenance of risky sexual behaviors, which have particularly devastating consequences in young women. This study examined whether (i) adolescent onset of cannabis use is associated with repeated voluntary unprotected sex in women and (ii) whether this association persists after accounting for correlated familial influences.

Design

General population sample of female twins.

Setting

Midwestern United States.

Participants

A total of 2784 sexually active twin women (15.5% African American) aged 18-27 years (assessed 2002-05), including 119 dizygotic (DZ) and 115 monozygotic (MZ) discordant pairs.

Measurements

Self-report interview data on cannabis use that first occurred prior to age 17
