The National Drug Abuse Treatment Clinical Trials Network (CTN) provides a means by which the National Institute on Drug Abuse (NIDA), treatment researchers, and community-based service providers cooperatively develop, validate, refine, and deliver new treatment options to patients in Community Treatment Programs (CTPs). The CTN Web site allows researchers to download de-identified data from completed CTN studies to conduct analyses that improve the quality of drug abuse treatment.
