Drug rehab and group therapy: do they work?

TheConversation: Rehab is the short name for residential rehabilitation, the best known treatment for drug and alcohol problems. It involves living with a group of people with the shared goal of changing drinking or drug habits. There are regular media reports of celebrities being sent to rehab by the courts, or choosing to “check themselves in”. Rehab is even the subject of television shows such as Celebrity Rehab with Dr. Drew, that aired from 2008 and 2012 in the United States; and Intervention. But rehab is more than a celebrity phenomenon. Thousands of Australians go to residential drug and alcohol rehab programs every year.
