Outpatient treatment gives treatment clients the opportunity to maintain certain responsibilities and aspects of their life-style while getting involved in drug treatment services. Outpatient treatment is a moderate amount of treatment, and should not be mistaken for the level of treatment provided in an inpatient or residential rehabilitation program that is much more extensive. Outpatient treatment might be well suited for somebody who has a brief history of drug abuse as an example, but will almost certainly not be sufficient for someone whose rehabilitation needs go beyond that which outpatient treatment is able to provide. Individuals dealing with substance abuse often require an extreme environmental change, because many of the things that prompt their substance abuse are strictly environmental. As an example, when someone is being physically or psychologically abused and this is triggering their drug abuse, there is no way for any rehab efforts to achieve success should they go back to such situations every day. In outpatient treatment, individuals can engage in group and one-on-one therapy, as well as family counseling services. In outpatient treatment, most centers offer services five to seven days each week on either a part time or full time basis for four weeks or longer in some cases.
