Perceived discrimination and drug involvement among black primary care patients who use drugs.

Perceived discrimination has been associated with disparities for Black patients on a variety of health outcomes. Studies have suggested that perceived discrimination is associated with drug use in Blacks, but they have been limited by use of samples with little drug use and single measures of drug involvement. The current study examined the association between perceived discrimination and multiple measures of drug involvement among a sample of 203 Black adult primary care patients who were participants in a randomized trial of screening and brief intervention for drug use. The main independent variable was everyday perceived discrimination. The three outcomes were frequency of drug use in the past ninety days, drug-related consequences, and total drug involvement risk severity score from the Alcohol, Smoking, and Substance Involvement Test [ASSIST]. Analyses were conducted using negative binomial regression models for frequency and consequence outcomes and median regression models for drug involvement risk. Greater perceived discrimination was not significantly associated with frequency of use, but was associated with more drug-related consequences and a higher drug use risk level. These findings suggest that perceived discrimination may be an important variable to consider when selecting drug intervention approaches for Black primary care patients.
