Cannabis Use Disorder Rising Dramatically Among Aging Veterans with HIV

Retrospective CohortStrong evidence
The takeaway

Cannabis use disorder diagnoses more than quadrupled among veterans aged 65+ with HIV from 2000 to 2022, with one in five people living with HIV receiving a CUD diagnosis during the study period.

HIV clinicians, geriatricians, addiction medicine specialists, VA healthcare providers, and public health researchers.

What the researchers found

20% of people living with HIV (PLWH) had a cannabis use disorder diagnosis between 2000 and 2022, with CUD consistently higher among PLWH vs. those without HIV (OR=1.14, 95% CI=1.11-1.18), and the greatest relative increase occurring among those aged 65+ (PLWH: 0.9% to 4.0%; PLWoH: 0.03% to 3.15%).

Why it matters

As people with HIV live longer on antiretroviral therapy, rising cannabis use disorder in this aging population is concerning because cannabis can interact with many prescription medications these patients take.

The numbers in context

N=185,372 (58,959 PLWH, 126,413 PLWoH); 45% Black NH, 35% White NH; mean age 48; 20% of PLWH had CUD; OR=1.14 for PLWH vs PLWoH; 65+ age group: 0.9%→4.0% (PLWH), 0.03%→3.15% (PLWoH)

How the study worked

Retrospective analysis of electronic health records from 185,372 individuals in the Veterans Aging Cohort Study-HIV (2000-2022), including 58,959 PLWH matched 1:2 to 126,413 people without HIV, examining CUD trends by age, race/ethnicity, sex, comorbidity, and HIV status.

What this study cannot tell us

VA population (mostly male) limits generalizability; ICD-based diagnosis may undercount CUD; cannot distinguish therapeutic from recreational use; increasing diagnostic coding awareness may inflate trends; observational design.

How to read the evidence

Large matched cohort with 22 years of longitudinal data from a national VA database, providing robust trend evidence despite limitations of diagnostic coding.

When this study was published

Published 2026; covers 2000-2022.

The bigger picture

The intersection of aging, HIV, and increasing cannabis use disorder represents a growing clinical challenge as providers must balance patients' cannabis use with complex medication regimens.

Questions still open

  • Is rising CUD among older PLWH driven by self-medication or changing cannabis availability? How does CUD affect antiretroviral therapy adherence and outcomes? Should HIV care include routine CUD screening?

Common questions

Is cannabis use disorder increasing among older adults?
Yes — among veterans aged 65+, cannabis use disorder diagnoses increased dramatically from 2000 to 2022, with rates quadrupling among those with HIV and rising over 100-fold among those without HIV.
Are people with HIV more likely to develop cannabis use disorder?
This study found that people living with HIV had 14% higher odds of CUD compared to matched individuals without HIV, possibly due to using cannabis to manage symptoms, side effects, or comorbidities.
