ETS is committed to improving the quality of substance use disorder treatment through involvement in research and the application of research findings to clinical practice. The ETS research department has participated in federally-funded research projects on a variety of topics related to substance use disorder treatment since the 1980s. Our agency has also been a community-based treatment program in the National Institute on Drug Abuse Clinical Trials Network since 2000. The results of these and other research projects have been published in prominent peer-review professional journals including the Journal of Substance Abuse Treatment and the American Journalof Public Health.
