The Los Angeles Times (12/23, Roan) “Booster Shots” blog reports, “A year-long project by experts nationwide has led to a new definition of the term” recovery from addiction or mental illness “that is meant to help doctors, counselors and policymakers.” Yesterday, the Substance Abuse and Mental Health Services Administration (SAMHSA) disclosed the new definition: “A process of change through which individuals improve their health and wellness, live a self-directed life, and strive to reach their full potential.” And, “as part of SAMHSA’s Recovery Support Strategic Initiative, researchers and other mental-health experts also clarified four major dimensions that support a life in recovery.” Those are health, home, purpose, and community.
