Exploring Differences in Cannabis Use and Harm Perceptions Among Sexual Minority and Heterosexual Females: A Brief...

Sexual minority women (SMW) have higher rates of cannabis use compared to heterosexual women, which may be partially attributed to lower harm perceptions. However, no study has examined if the association between harm perceptions and cannabis use is stronger for SMW than heterosexual women. This study examined if sexual identity (SMW vs. heterosexual woman) moderated the association between harm perceptions and past 30-day cannabis use among a sample of female young adults (18-25 years old).

Participants were 949 (29.8% SMW; Mean age = 24.33; 92.1% non-Hispanic White) females (99.3% cisgender) recruited from Amazon Mechanical Turk who reported weekly cannabis use. Participants reported how many days they used cannabis in the past 30-days and how harmful they perceived cannabis to be to their health (not at all/slightly/somewhat harmful vs. very/extremely harmful). An Analysis of Covariance examined the study aim.

A significantly larger percentage of heterosexual women perceived cannabis to be very/extremely harmful to their health than SMW (45.2% vs. 22.6%). Those who perceived cannabis to be very/extremely harmful reported more frequent cannabis use in the past-30 days. SMW who perceived cannabis to be very/extremely harmful reported more frequent cannabis use relative to those who held lower harm perceptions; there were no significant differences for heterosexual women.

SMW may perceive cannabis as harmful because they may be experiencing health consequences from frequent use. It may be important for interventions and public health campaigns to be tailored specifically to SMW and include information about the potential harms of cannabis use.
