This is an interesting question. In what way is it enabling? Many people who suffer from addiction want to get better, they recognize it's a real problem, but if it was just a choice like should I wear my blue shirt or my red shirt, rehab/inpatient treatment centers wouldn't be necessary. The addiction becomes controlling... it begins to make the choices. It may seem silly to someone who doesn't suffer from addiction, but when you have it - often times it really has you. Its tough, and although there are many people who can do inpatient treatment and fight after successfully with outpatient, there are many people who can't. It is a long and difficult battle. So, I don't think there's a number assigned to a perrsons allotted admissions to rehab... as long as they're seeking treatment, be as supportive as you can
