Individuals who would like to maintain a lot of flexibility within their lives can engage in an outpatient rehab should they need rehabilitation for substance abuse. Outpatient rehab makes it possible for the rehab client to participate in rehab services without the commitment one would normally have to agree 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 might appear to be an opportune option, it isn't for everyone. Those who choose an outpatient rehab will typically take part in meetings and take part in therapy and treatment services part-time daily or several days a week. This is helpful for individuals who have just completed a more complete inpatient or residential program as a good aftercare or maintenance step, and for someone with only a brief history of drug use which is really a very small amount of clients. For somebody with more serious drug abuse and dependency issues, inpatient or residential alcohol and drug rehabilitation centers which provide treatment on a long-term basis will be the more effective treatment option.
