“Objectives: A significant clinical concern in the era of Pre-Exposure Prophylaxis (PrEP) is the increased incidence of HIV Anti-Retroviral Drug Resistance Mutations (ARV-DRM). Previous research has indicated that there is an association between substance use and failed viral suppression, which can lead to ARV-DRM. The goal of this retrospective study was to investigate whether substance use as determined by at least one positive urinalysis screen is associated with increased/decreased odds of having a ARV-DRM.
Methods: This study used firth logistic regression analyses of data retrieved from the National NeuroAIDS Tissue Consortium Data Coordinating Center to examine the relationship between substance use and ARV-DRM. The dataset analyzed 614 participants with the following criteria: HIV+ status, at least one paired plasma and cerebrospinal fluid (CSF) viral load measurement, at least one urinalysis of substance use, at least 18 years of age, and analysis of DRM in CSF/Plasma.
Results: Cannabis use was a significant predictor of ARV-DRM and was associated with a lower odds of having ARV-DRM (odds ratio=0.189), after accounting for demographic variables and the interaction between polysubstance use and cannabis use. A significant negative relationship was observed between a cannabis positive test and high viremia (>1,000 copies/mL) but not between a cannabis positive test and CSF Escape (viral load CSF>viral load plasma).
Conclusions: The above results may suggest an immunomodulatory role for cannabis that impacts the propensity for ARV-DRM. These findings could incentivize future research to further investigate effects of cannabis use on the development of HIV ARV-DRM.”

“We have found that cannabis use is significantly associated with a decreased likelihood of HIV ARV-DRM and suggest that cannabis use may be a protective factor against the development of anti-retroviral drug resistance mutations. “
