Individuals who want to maintain a lot of flexibility in their lives can engage in an outpatient rehab when they need rehab for substance abuse. Outpatient rehab will allow for the treatment client to take part in treatment services with the same commitment one would ordinarily have to consent to in an inpatient or residential alcohol and drug rehab program. This doesn't always work in the rehabilitation client's favor however, specifically those clients who need to address substantial substance abuse problems. So although an outpatient rehab may seem like a convenient option, it isn't for everyone. Those who choose an outpatient rehab will generally attend meetings and take part in counseling and rehabilitation services on a part-time basis every day or several days each week. This is helpful for many who have just completed a more extensive inpatient or residential program as an effective aftercare or upkeep step, or someone with only a short history of substance abuse which is really a very small percentage of clients. For somebody with more significant drug abuse and dependency problems, inpatient or residential alcohol and drug rehabilitation centers which offer rehabilitation on a long-term basis will be the more advantageous rehabilitation choice.
