Outpatient treatment gives rehab clients the opportunity to maintain certain responsibilities and aspects of their lifestyle while taking part in drug and alcohol treatment services. Outpatient treatment is a moderate degree of rehab, and should not be mistaken for the level of treatment provided within an inpatient or residential rehabilitation setting which can be a lot more extensive. Outpatient treatment may be suitable for anyone who has a brief history of drug or alcohol use for example, but will certainly not be sufficient for a person whose rehab needs go beyond what outpatient treatment is able to provide. Individuals involved in drug abuse often need an extreme environmental change, because many of the things which trigger their drug and alcohol use are purely environmental. By way of example, when someone has been physically or emotionally mistreated and this is triggering their drug or alcohol use, there is no way for any rehab endeavours to achieve success should they return to such conditions each day. In outpatient treatment, clients can take advantage of group and individual therapy, along with family therapy services. In outpatient treatment, most centers offer services six or seven days a week on either a part time or full-time basis for four weeks or longer in some instances.
