Geographic Differences in Cannabis Use and Cannabis Use Disorder in the US Veteran Population

Full Article Read the complete peer-reviewed article in J Clin Psychiatry. Article Summary Veterans often use cannabis for chronic pain, PTSD, anxiety, and insomnia, yet cannabis use disorder carries meaningful psychiatric and functional burden. This study shows that cannabis risk is not evenly distributed across the country, giving clinicians and health systems a clearer map of where routine screening and treatment capacity may be most needed. Patient Summary Researchers studied whether cannabis use and signs of cannabis use disorder varied by where veterans live in the United States. In a national survey of about 2,400 veterans, they looked at how many had used cannabis in the past 6 months and how many showed signs of a cannabis-related problem, which matters because veterans may use cannabis for symptoms like pain, anxiety, sleep trouble, or trauma-related stress.
