This session will review the history of evidence-based treatment and treatment components. Recent changes have called medication assisted treatment the gold standard as an element of treatment. Current trends including polysubstance use and re-emergence of methamphetamine use require both a broad and narrow approach to determining effective elements of treatment. This allows the development of effective treatment protocols to manage the needs of a wide range of individuals seeking treatment. This session will allow participants to list key treatment elements with in-depth research support, describe recent applications of the term “gold standard”, as well as identify implications for ongoing practice.  These objectives will be achieved through a multimedia PowerPoint presentation with didactic and experiential learning elements.
