Authors: Wilfrid Noel Raby, Kenneth M. Carpenter, Jami Rothenberg, Adam C. Brooks, Huiping Jiang, et al
American Journal on Addictions, July/August 2009

Naltrexone is a theoretically promising alternative to agonist substitution treatment for opioid dependence, but its effectiveness has been severely limited by poor adherence. This study examined, in an independent sample, a previously observed association between moderate can…
