The University of Southern California's Tobacco Center of Regulatory Science (USC TCORS) for Vulnerable Populations is one of 9 Tobacco Centers of Regulatory Science in the U.S. We were created to serve in the production of relevant scientific data to inform the regulatory decision making at the Food and Drug Administration's (FDA) Center for Tobacco Products. Additionally, we are here to educate and train the next generation of tobacco regulatory scientists.
