Outpatient treatment gives rehabilitation clients the chance to maintain certain responsibilities and aspects of their life-style while taking part in drug rehab services. Outpatient treatment is a moderate degree of rehab, and should not be mistaken for the amount of rehab provided in an inpatient or residential treatment setting which can be much more extensive. Outpatient treatment may be ideal for someone who has a brief history of substance abuse for example, but will most definitely not be adequate for someone whose rehab needs go beyond that which outpatient treatment is able to provide. Individuals dealing with substance abuse often need an extreme change of environment, because most of the things that trigger their drug and alcohol use are strictly environmental. For instance, if someone else is being physically or psychologically mistreated and this is triggering their substance abuse, it's impossible for any treatment endeavours to achieve success if they return to such situations every day. 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 5 to 7 days per week on either a part-time or full-time schedule for four weeks or longer in some cases.
