Outpatient treatment gives rehab clients the opportunity to maintain specific responsibilities and aspects of their way of life while taking part in drug and alcohol rehabilitation services. Outpatient treatment is a moderate degree of rehabilitation, and should not be mistaken for the amount of treatment offered in an inpatient or residential rehabilitation setting which can be significantly more intensive. Outpatient treatment could be ideal for a person who has a short history of drug or alcohol use as an example, but will almost certainly not be sufficient for somebody whose rehab needs exceed what outpatient treatment is able to provide. Individuals dealing with drug abuse often require an extreme change of environment, because many of the things that trigger their substance abuse are strictly environmental. For example, when someone has been physically or psychologically mistreated and this is triggering their substance abuse, there is no way for any rehab endeavours to succeed if they go back to such circumstances every day. In outpatient treatment, individuals can benefit from group and individual therapy, in addition to family therapy services. In outpatient treatment, most programs offer services 6 or 7 days per week on either a part-time or full-time basis for four weeks or longer in some cases.
