Gabrielle Glaser in The Atlantic:

The 12 steps are so deeply ingrained in the United States that many people, including doctors and therapists, believe attending meetings, earning one’s sobriety chips, and never taking another sip of alcohol is the only way to get better. Hospitals, outpatient clinics, and rehab centers use the 12 steps as the basis for treatment. But although few people seem to realize it, there are alternatives, including prescription drugs and therapies that aim to help patients learn to drink in moderation. Unlike Alcoholics Anonymous, these methods are based on modern science and have been proved, in randomized, controlled studies, to work.
