Alcohol use is common among active duty service members and veterans for a variety of reasons, including institutional culture, military-specific risk factors, and co-occurring mental health disorders such as PTSD. Despite the US military historically tolerating, if not encouraging, alcohol use, in more recent years it has increasingly recognized the importance of preventing, diagnosing, and treating alcohol use disorder (AUD). This is important for mission readiness as well as attending to the mental and physical health of service members, and ultimately veterans. The standard of care includes psychosocial treatments, such as twelve-step facilitation, motivational interviewing, cognitive behavioral therapy, and Seeking Safety, as well as evidence-based pharmacotherapies. Such interventions can be delivered across a continuum of care from outpatient to inpatient or residential settings. Left untreated, unhealthy alcohol use and AUD lead to myriad poor health outcomes including liver disease, neurological disorders, worsened mental health conditions, and increased suicide risk. Moderate-to-severe AUD is usually a lifelong condition, necessitating robust treatment programs within the VA healthcare system to serve those who have served their nation.
