Variations in Risk and Motivations for Substance Use over the Course of Military Service

Abstract

Background

Epidemiological data identify risk factors related to substance use among military service members to inform prevention and treatment. Less is known about how motivations and risks for substance use vary over a military service career. The study goal was to explore substance use patterns and motivations among a sample of United States undergraduate student veterans in order to identify periods of risk. Methods: Qualitative interviews were conducted (n = 31) between December 2018 and April 2019. Transcripts were coded in ATLAS.ti using thematic content analysis. Results: Interviews revealed complex motivations around substance use and identified key periods of risk. 1) Pre-service: Participants reported using alcohol and marijuana, primarily during social activities. 2) During service: Participants described a culture of heavy alcohol and tobacco use in social contexts, but little use of other substances. Post-deployment was a notable exception, when some reported heavier alcohol use and use of other drugs, including opiates, cocaine, and ecstasy. 3) Post-service: Transitioning out of the military was described as difficult; some participants reported heavier use of substances during this period. Some participants quit smoking after military service, or switched to vaping. Others reported use of alcohol and/or marijuana to calm themselves, relieve stress, and enable sleep. Conclusions: These data indicate that the periods immediately following deployment and transition out of the military may be especially high-risk for heavy substance use and use of a broader range of substances. This highlights the need for tailored interventions and messaging at different points of military service, particularly during periods of greatest risk.
