Use and perceptions of opioids versus marijuana among medical populations: Perspectives from people living with HIV and cancer survivors Pubblico
Potts, Jessica (Spring 2018)
Abstract
Public health concerns regarding opioids and marijuana have implications for their medical use. This study examined motives for use and perceived barriers in relation to opioid and marijuana use and interest in use among US adult survey participants living with HIV (PLWH, n=304) or who are cancer survivors (n=194) recruited via social media in Summer 2018. Participants were an average 34.29 years old, 51.6% male, and 58.4% White. Overall, 25.7% (16.1% of PLWH, 40.9% of cancer survivors) reported current (past 30-day) use of opioids, 27.5% (PLWH: 18.1%; cancer survivors: 42.5%) reported current (past 30-day) use of marijuana, and 25.1% (PLWH: 16.1%; cancer survivors: 39.7%) reported current (past 30-day) use of both analgesics. The most common motives for use for either/both drugs were to cope with pain and stress/anxiety (>50%). Highest-rated barriers to using either or both drugs were missing symptoms of worsening illness and concerns about addiction. Per multivariable regression, current opioid use was correlated with greater motives for use (OR=2.32) and being older, female, Black, and higher income (Nagelkerke R-square=.627). Among opioid nonusers, greater interest in use was correlated with greater motives for use (B=0.42), greater barriers (B=0.02), history of cancer, and being female, married/cohabitating, and lower income (Adjusted R-square=.698). Current marijuana use was correlated with greater motives for use (OR=1.62), greater barriers (OR=1.18), history of cancer, and being older and White (Nagelkerke R-square=.702). Among marijuana nonusers, greater interest in use was correlated with greater motives for use (B=0.64), fewer barriers (B=-0.03), history of cancer, and being female, unmarried, and lower income (Adjusted R-square=.802). While motives for use and barriers for both drugs were similar, these constructs were differentially associated with use and interest in use across drugs.
