Outpatient treatment gives rehabilitation clients the chance to sustain certain obligations and elements of their lifestyle while taking part in alcohol and drug treatment services. Outpatient treatment is a moderate amount of rehab, and should not be mistaken for the amount of rehabilitation provided in an inpatient or residential treatment setting that is significantly more extensive. Outpatient treatment could be suited to someone who has a short history of drug or alcohol use for instance, but will certainly not be adequate for someone whose rehabilitation needs go beyond that which outpatient treatment is able to offer. Individuals involved in substance abuse often require a considerable environmental change, because many of the things that trigger their substance abuse are strictly environmental. By way of example, when someone has been physically or psychologically abused and this is triggering their drug abuse, there is no way for any treatment endeavours to have success whenever they return to such situations on a regular basis. In outpatient treatment, individuals can engage in group and one-on-one counseling, as well as family therapy services. In outpatient treatment, most centers will provide services six or seven days a week on either a part-time or full-time basis for four weeks or longer in some cases.
