Cannabis Use and Perceptions Among Current and Former Military Service Members.

Background: Research indicates separation from the military may result in increased risk of alcohol use. However, there is little data on cannabis use among military service members, particularly when examining the period after separation from military service. This research examines cannabis-related perceptions and use among U.S. Army Reserve/National Guard (USAR/NG) current and former soldiers.

Methods: Data come from Operation: SAFETY (Soldiers And Families Excelling Through the Years), an ongoing study examining health among male and female USAR/NG soldiers. The current sample was comprised of 401 current and former USAR/NG soldiers. Logistic regression models examined the associations between past-year cannabis use, military status (i.e., current versus former), attitudes towards recreational cannabis, perceived ease of access, and perceived risk of cannabis use, while controlling for age, problematic alcohol use, and current cigarette smoking.

Results: Overall, 7.4% of current and 20.3% of former military service members used cannabis in the past year. Favorable attitudes towards cannabis use and perceived ease of accessing cannabis were associated with increased odds of use among all soldiers. In adjusted models, former military members had greater odds (AOR = 5.28, 95% CI = 2.16, 12.87) of past-year cannabis use compared to current service members.

Conclusions: Findings indicate that separation from the military may be an important risk factor to consider when assessing cannabis use in the military. Additional research is needed to examine socioenvironmental factors (e.g., access to post-deployment support services and healthcare, state legalization laws, other behavioral health conditions) that contribute to former service members' cannabis use.
