Cannabis Usage Trends Among Men who have Sex with Men in the United States, 2014-2018 Pubblico

Abstract

Background: The role of cannabis in sexual health behaviors and outcomes among American men who have sex with men (MSM) is poorly understood. As medical and recreational legalization become more common, usage is likely to increase. This study evaluates cannabis usage trends and associations with sexual health behaviors/outcomes using five years of survey data from MSM in the United States.

Methods: The American Men’s Internet Survey (AMIS) is a serial, cross-sectional survey of men who have sex with men in the United States. Using five years of data from AMIS (n=37,346), we evaluate cannabis usage patterns using the Cochrane-Armitage test for trend and estimate prevalence ratios of cannabis usage and sexual health behaviors/outcomes through modified Poisson regression with robust variance.

Results: Cannabis usage is increasing among American MSM. High frequency use is also increasing among this population. Usage is associated with more serodiscordant condomless anal intercourse (aPR 1.10, 95% CI: 1.04, 1.16), higher PrEP use (aPR 1.11, 95% CI: 1.01, 1.22), and fewer STI diagnoses (aPR: 0.89, 95% CI: 0.82, 0.96).

Conclusions: Cannabis use is increasing among this population. Cannabis users might engage in riskier sexual behaviors than nonusers; however, they also employ protective health measures at a higher frequency.
