ICD’s Sylia Wilson and Psychology’s Scott Vrieze have received a grant from the National Institute on Drug Abuse. The grant will total $4.6 million over the course of 5 years in support of their research titled “Understanding the Links Between Parental and Adolescent Substance Use: Complementary Natural Experiments Using the Children of Twins Design.”

The grant has been awarded to Wilson and Vrieze, the MPIs at the Minnesota Center for Twin and Family Research, and to Soo Rhee and John Hewitt, the MPIs at the Institute for Behavioral Genetics, at the University of Colorado-Boulder. In this project, Wilson and colleagues seek to identify mechanisms of parent-child transmission of substance use, determine effects of cannabis legalization on parents, families, and adolescents, and understand the influence of behavioral disinhibition on adolescent substance use in the context of cannabis legalization in two large, population-based, twin family samples in Colorado and Minnesota.
