If the clinic people didn't know what to do, WTF were they doing working in a rehab clinic? That's not an unusual event at this kind of facility. People are in rehab because they're out of control. There's always the possibility that this is a Rehab in name only spa where the stars come for a drug-free vacation experience, but having dealt with EVERY kind of junkie and alcoholic (I spent five years working 6th Street in Austin), I don't see this as being something at all unexpected from someone either stoned or going through withdrawal.
