Outpatient treatment gives rehab clients the opportunity to sustain certain responsibilities and aspects of their way of life while taking part in drug rehabilitation services. Outpatient treatment is a moderate amount of treatment, and should not be mistaken for the amount of rehabilitation offered within an inpatient or residential rehabilitation setting that is much more extensive. Outpatient treatment may be well suited for somebody who has a short history of drug or alcohol use for instance, but will most definitely not be sufficient for an individual whose rehab needs go beyond that which outpatient treatment is able to provide. Individuals involved in drug abuse often require a considerable change of environment, because most of the things which prompt their drug and alcohol use are purely environmental. As an example, if a person has been physically or emotionally abused and this is prompting their drug or alcohol use, there is no way for any rehab efforts to have success whenever they go back to such situations each day. In outpatient treatment, clients can engage in group and one-on-one counseling, as well as family counseling services. In outpatient treatment, most programs offer services five to seven days per week on either a part time or full-time basis for four weeks or longer in some instances.
