Abstract: In health sociology, the prevailing consensus is that socioeconomic status lowers illness risk. This model neglects the fact that unhealthful consumption patterns may covary with affluence. The current study examines consumption of drugs and alcohol among affluent U.S. college students. I hypothesized that undergraduate students from high-SES households would have high rates and levels of drug and alcohol consumption. Using data from 18,611 18- to 24-year-old undergraduates across 23 public and private institutions, I found that high-SES undergraduates were more likely than peers to use marijuana, choose varied drugs, consume alcohol frequently, and use alcohol and substances to cope with stress. The first three results were robust after controlling for gender, race, residence type, and relationship status. Marital status and race were stronger predictors than SES—Asians and married students were the least likely to use alcohol and drugs.
