Outpatient treatment gives rehab clients the chance to maintain certain obligations and elements of their way of life while taking part in drug treatment services. Outpatient treatment is a moderate level of rehab, and should not be mistaken for the level of rehab offered in an inpatient or residential treatment program which can be much more intensive. Outpatient treatment may be ideal for a person who has a brief history of drug or alcohol use for example, but will most surely not be adequate for a person whose treatment needs go beyond that which outpatient treatment is able to offer. Individuals dealing with drug and alcohol use often need a considerable environmental change, because many of the things that trigger their substance abuse are strictly environmental. For example, if someone is being physically or psychologically mistreated and this is triggering their drug or alcohol use, there is no way for any rehabilitation endeavours to achieve success whenever they return to such situations each day. In outpatient treatment, clients can engage in group and one-on-one therapy, in addition to family counseling services. In outpatient treatment, most centers will provide services 5 to 7 days each week on either a part-time or full time schedule for four weeks or longer in some cases.
