DESPR's Prevention Research Branch will improve the nation's public health status through supporting a program of basic, clinical, and services research on the development, testing, and translation of prevention interventions that target the initiation of drug use, the progression to abuse and dependence, and the transmission of HIV infection among diverse populations and settings.

Research Goals:

  • Support high quality research on the development, testing, and implementation of prevention interventions in a variety of contexts across the course of development:
