QUOTE : Fewer than one-quarter of heroin addicts who receive abstinence-only counseling and support remain clean two or more years. The recovery rate is higher, roughly 40 to 60 percent, among those who get counseling, support group, and medication-assisted treatment such as methadone, buprenorphine, or naltrexone. “We know from other countries that when people stick with treatment, outcomes can be even better than fifty percent,” Lembke, the addiction specialist, told me. But most people in the United States don’t have access to good opioid-addiction treatment, she said, acknowledging the plethora of cash-only MAT clinics that resemble pill-mill pain clinics as well as rehabs that remain staunchly anti-MAT.
