AI Summary

This longitudinal study tracked 119 people living with HIV who use cannabis daily over 6 months to understand how cannabis use, concurrent cocaine use, and various health symptoms interact to affect their healthcare engagement. The research reveals a surprising finding: participants with less-frequent cannabis use at the study's start experienced a 46.7% decline in HIV clinic visits by the end of the study period, suggesting that frequent cannabis use may actually encourage people to maintain regular HIV medical care. This counterintuitive result highlights the complex relationship between cannabis use patterns and healthcare-seeking behavior in this vulnerable population.

The study identified important differences between those who also used cocaine versus those who only used cannabis. Cocaine co-users experienced worse sleep quality and greater overall healthcare utilization, particularly for non-HIV-related medical visits, yet they actually used cannabis less frequently than those without cocaine use. Both groups showed strong correlations between physical symptoms like poor sleep, fatigue, and appetite loss with psychiatric symptoms including depression and anxiety, though cocaine use didn't significantly worsen depression or anxiety itself.

The findings underscore that cannabis use among people living with HIV exists within a complex web of other substance use, multiple health symptoms, and healthcare patterns. Rather than viewing cannabis as simply harmful or beneficial, clinicians and public health officials need to recognize how cannabis use frequency relates to broader health engagement and treatment adherence. The data suggests that cannabis may serve as a marker for consistent medical care-seeking behavior, though the underlying mechanisms remain unclear and warrant further investigation.

📄 Original Abstract

Cannabis use is common among persons living with human immunodeficiency virus (HIV, PLWH) and has been associated with disrupted sleep, psychiatric symptoms, and increased healthcare utilization. However, the influence of concurrent cocaine and cannabis use on symptom trajectories and healthcare engagement remains unclear. One hundred nineteen PLWH who reported daily cannabis use were assessed longitudinally: baseline, 3-month, and 6-month follow-up. Participants were stratified into concurrent cocaine users vs. non-users based on urine drug screen results (Coc + n = 34 vs. Coc- n = 85). Assessments included substance-use characteristics, viral load, healthcare utilization (HIV-specific vs. non-specific medical visits), HIV-related symptoms (poor sleep, fatigue, pain, poor appetite), and psychiatric symptoms (depression, anxiety). From baseline to 6-month follow-up, HIV clinic visit frequency declined 46.7% (p = 0.002), which was predicted by less-frequent baseline cannabis use (p = 0.03). Poor sleep, fatigue, and poor appetite reliably correlated with psychiatric symptom severity (rs = 0.23-0.57), whereas pain severity was most closely linked to non-HIV-specific healthcare utilization (rs = 0.23-0.36). Cocaine co-use was associated with greater non-HIV-specific healthcare utilization, worse sleep, and less-frequent cannabis use (ps < 0.05). Among daily cannabis-using PLWH, less-frequent cannabis use at study baseline predicted a 47% decline in HIV clinic visits suggesting that frequent cannabis use (or associated factors) may perpetuate continued HIV healthcare utilization. Cocaine co-use was associated with greater healthcare utilization, worse sleep quality, and less-frequent cannabis use, but did modulate self-reported depression or anxiety symptoms. In sum, our findings show a complex interplay between longitudinal patterns of cannabis use, somatic and psychiatric symptom severity, and healthcare utilization among PLWH. This study was registered at ClinicalTrials.gov (NCT01536899).
