Brief summary (from the registry)
Self-medication of pain by consuming alcohol and marijuana is common. However, the research regarding pain as a determinant for alcohol and marijuana use has relied on laboratory pain induction paradigms with limited clinical relevance. The study will assess demand for alcohol and marijuana before and after delayed onset muscle soreness (DOMS) induction in co-users. This will provide a clinically relevant, but time-limited, model for the effects of musculoskeletal pain on demand.
