What Dave's Wife said. If he is in fact, medically detoxed, he should be ok, medically speaking. (which is different from being a happy camper and also different from feeling well or being peasant to deal with, physically.) If he was not sufficiently medically detoxed before discharge to be medically stable, and there are any signs of seizure, psychosis, or other detox symptoms you are concerned are life threatening or which you simply are not physically or psychologically equipped to deal with, call 911.
