Abstract
G. Alan Marlatt's research and other professional efforts have profoundly influenced the science and practice of harm reduction. Marlatt's balanced placebo drinking research challenged prevailing attitudes about the loss of control and illustrated the potency of beliefs in predicting drinking behavior. His courageous defense of the Sobells during the controlled drinking controversy was a first step toward legitimizing harm reduction goals. His harm reduction interventions are best practices for college student drinking, and the excellence of those programs has elevated the stature of harm reduction interventions in the US. He developed mindfulness-based harm reduction strategies for those managing relapse or seeking moderation goals in treatment. His interpretation of the science of harm reduction compelled him to speak on behalf of consumers, advocating for alternative forms of treatment rather than a one-size-fits-all model. He collaborated with community stakeholders to extend culturally relevant harm reduction programs into traditionally disempowered communities. Somehow, Marlatt also found time to mentor the next generation of harm reduction scholars and practitioners. The stature of harm reduction today is largely the result of Marlatt's dedication and professionalism. Though he is sorely missed, the field will be continued to be shaped by his ideas for many years to come.
