About
Research
Magdalena Cerdá's research focuses on the effects that drug and health policies have on drug use, and on the ways the urban context shapes violence. Current research focuses on the impact of disasters on overdose, and the effects of state and municipal drug policies on drug-related harms. She is also evaluating the first overdose prevention centers in New York City and Rhode Island.
