U.S. researchers investigated the effects of cannabis use on continuation of antiretroviral therapy (ART) in HIV positive patients.
252 patients completed the interview, 175 (69 per cent) were on ART and 168 (67 per cent) provided ART adherence data. 41 of these 168 (24 per cent) used cannabis.
There was no association between ART adherence and cannabis use. However, among HIV positives who suffered from nausea those who used cannabis were three times more likely to continue their ART therapy than non-users. (1)
