Just Can’t Get Enough: Addiction & the Brain
May 4, 2016
Only a small percentage of people who try an illicit drug will go on to develop addiction. What makes one more vulnerable to addiction than another? Theories abound, from troubled childhoods to work stress to genetics. Psychiatrist Edmund Griffin explains how epidemiology, cocaine-addicted rats, and molecular neuroscience all help to shed light on one society’s most troubling questions: Why is it that some people just can’t get enough?

The SciCafe series is proudly sponsored by Judy and Josh Weston.
- A landmark paper that describes a biological mechanism for the the "Gateway Hypothesis" that chronic exposure to drugs like nicotine, alcohol, or marijuana can increase vulnerability to an illicit drug like cocaine.
- Review paper on the role of nicotine as a gateway drug.
- A recent lecture (Dr. Griffin), at the NYU McSilver Institute for Poverty Policy and Research: How new insights from translational neuroscience inform clinical and social interventions in mental health.
Edmund Griffin is an Assistant Professor of Clinical Psychiatry in the Division of Neurobiology, Brain and Behavior in the Department of Psychiatry Columbia University. His research focuses on how environmental exposures alter the brain and increase vulnerability to compulsive drug use.
