Outpatient treatment gives treatment clients the opportunity to maintain specific responsibilities and elements of their way of life while taking part in drug and alcohol treatment services. Outpatient treatment is a moderate degree of rehabilitation, and should not be mistaken for the degree of rehabilitation offered in an inpatient or residential rehabilitation program which can be much more intensive. Outpatient treatment could be suitable for somebody who has a brief history of drug abuse as an example, but will almost certainly not be sufficient for someone whose treatment needs exceed that which outpatient treatment is able to provide. Individuals dealing with drug and alcohol use often need a considerable change of environment, because most of the things that trigger their substance abuse are strictly environmental. By way of example, if a person is being physically or psychologically mistreated and this is prompting their substance abuse, there is no way for any rehabilitation endeavours to achieve success if they go back to such conditions on a regular basis. In outpatient treatment, clients can benefit from group and individual therapy, as well as family therapy services. In outpatient treatment, most centers will provide services five to seven days a week on either a part time or full-time basis for thirty days or longer in some cases.
