Cannabis Use Disorder: Prevalence and Risk Factors Among Older US Veterans

Recent research reveals that over one-third of older U.S. veterans who reported using cannabis in the past month meet the diagnostic criteria for cannabis use disorder, highlighting a significant and underrecognized public health concern. This finding draws attention to a vulnerable population where cannabis use intersects with the complexities of aging, mental health, and long-term care, underscoring the need for more consistent screening and tailored interventions across clinical environments.

In a study published in JAMA Network Open, researchers examined cannabis consumption patterns among veterans aged 65 to 84. Approximately 10 percent of participants reported using cannabis in the previous 30 days, and among those users, more than one-third were identified as having cannabis use disorder. Notably, the likelihood of developing CUD increased with frequency of use and was especially pronounced among individuals who primarily consumed cannabis through inhalation methods, such as smoking or vaping.

These results present critical implications for clinicians working in geriatrics, psychiatry, and primary care. Traditional assumptions that older adults face a lower risk for substance misuse are challenged by this data, and healthcare providers are encouraged to integrate regular substance use screenings into routine care for older patients—especially veterans. Understanding the specific risk profiles associated with cannabis use in this demographic can enable providers to offer earlier and more personalized interventions.

The evidence also reinforces the importance of addressing the method of cannabis use, not just the frequency. Frequent, inhaled cannabis use was associated with significantly higher odds of developing cannabis use disorder, signaling a need for targeted education around safer use practices and potential risks. By acknowledging these consumption patterns, providers can better guide their patients toward informed decisions while also considering alternative strategies for managing chronic pain, anxiety, or insomnia—common reasons for cannabis use among older adults.

As cannabis legalization expands and cultural perceptions shift, the risks of cannabis misuse in aging populations must not be overlooked. These findings call for the implementation of evidence-based policies and clinical tools that prioritize prevention, education, and tailored treatment strategies for older veterans, helping safeguard both mental and physical health as patients age.
