Q: Do they offer any Aftercare and if so, is it included in the price of the program? A: Residential Alcohol and Drug Treatment Centers should offer some type of Aftercare Program. Relapse occurs more in the first month out of the treatment center than in any other month. Aftercare Programs should be 6 months to a year in duration and should include relapse prevention, as well as provide support for the clients during the transitional phases he or she faces while re-entering the mainstream of life.
