Prevalence and Mental Health Correlates of Illegal Cannabis Use Among Bisexual Women

This study reports the prevalence of cannabis use among bisexual women in Ontario, Canada, and identifies correlations among levels of cannabis use (no use, some use, active use) and measures of mental health and social support. Analysis focused on 262 bisexual women from a bisexual mental health study using respondent-driven sampling. Among networked bisexual women in Ontario, Canada, the weighted prevalence of past-year cannabis use was 33.6%, with 13.8% of bisexual women using cannabis twice or more per week. Cannabis use was positively associated with social support, gay community involvement, outness to family, and depression. There was no significant association between cannabis use and anxiety, posttraumatic stress disorder, antibisexual experiences, or suicidal ideation. Bisexual women's rate of past-year cannabis use is more than 5 times that for Canadian women in general, and is consistent with rates for bisexual women found in U.S. studies.
