Introduction
This workshop focused on presenting and discussing current, cutting-edge diffusion, structural, and peer-driven intervention/prevention approaches among adult, adolescent, and ethnic minority drug-using populations. Representatives of the Clinical Trials Network (CTN) Steering Committee, the CTN HIV Special Interest Group, and staff of the Center For Clinical Trials Network (CCTN) at the National Institute on Drug Abuse planned this meeting in hopes of facilitating the transfer of these research-based approaches into community addiction treatment programs.
