Dealing with addiction to drugs and alcohol is extremely hard on the addicts and their loved ones who are willing to go to extreme lengths to try and wean them off it. In his latest close analysis, John Oliver says that there is no formal definition of what constitutes addiction rehabilitation, no standards for what constitutes proper treatment, and no proper measures of whether these organizations are succeeding. So it should not be surprising that a rehabilitation industry has sprung up that promises to cure addiction for a stiff fee with little or no evidence that what they do actually works.
