The Overdose Prevention Initiative (OPI) works on the complex and changing nature of the drug overdose epidemic through prevention and research activities. OPI collects and shares data on fatal and non-fatal drug-related overdoses, drug-related overdose risk factors, prescriptions, and substance use. Through state and local partnerships, OPI supports substance use prevention programs, harm reduction tools and strategies, public awareness and education, and safe and effective prescribing and treatment practices.
