Outpatient treatment gives rehabilitation clients the ability to sustain specific responsibilities and elements of their lifestyle while taking part in drug rehab services. Outpatient treatment is a moderate amount of treatment, and should not be mistaken for the degree of treatment provided within an inpatient or residential treatment setting which can be significantly more intensive. Outpatient treatment might be ideal for somebody who has a short history of substance abuse for example, but will most surely not be sufficient for somebody whose treatment needs exceed what outpatient treatment is prepared to offer. Individuals dealing with substance abuse often need an extreme environmental change, because many of the things which prompt their substance abuse are purely environmental. For example, if someone else has been physically or emotionally abused and this is prompting their drug abuse, there is no way for any rehab efforts to achieve success if they return to such situations on a daily basis. In outpatient treatment, individuals can take advantage of group and individual therapy, as well as family therapy services. In outpatient treatment, most centers offer services six or seven days per week on either a part time or full time schedule for four weeks or longer in some cases.
