About

Self-medication of pain with alcohol is a common, yet risky, behavior among individuals with chronic orofacial pain. Chronic pain status may affect the degree to which alcohol use relieves pain, but the independent contributions of pain chronification and alcohol-related expectations and conditioning have not been previously studied. This project addresses this gap in knowledge and will inform further research and clinical/translational efforts for reducing risk associated with these behaviors.
