This research examines simultaneous and concurrent polysubstance use and the behavioral economic mechanisms underlying them. Using daily diary surveys and multi-level modeling, the study investigates alcohol demand and delay discounting as predictors of risky substance use patterns, aiming to inform interventions for individuals who use multiple substances.

This research examines how sugar consumption and impaired reward sensitivity predict later alcohol-related behaviors in rats. Findings show that addiction-like responses to sugar can forecast alcohol responses, suggesting shared neural mechanisms. Understanding these early behavioral markers may help identify addiction risk factors and inform prevention strategies.
