Outpatient treatment gives rehabilitation clients the opportunity to maintain specific obligations and aspects of their life-style 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 treatment offered in an inpatient or residential rehabilitation program which can be significantly more intensive. Outpatient treatment may be ideal for anyone who has a brief history of drug or alcohol use for instance, but will almost certainly not be sufficient for an individual whose treatment needs exceed what outpatient treatment is prepared to provide. Individuals involved in drug abuse often need a considerable change of environment, because many of the things which trigger their drug and alcohol use are purely environmental. As an example, when someone has been physically or psychologically mistreated and this is triggering their substance abuse, there is no way for any rehabilitation endeavours to succeed if they go back to such situations each day. In outpatient treatment, individuals can engage in group and one-on-one counseling, along with family counseling services. In outpatient treatment, most programs will provide services five to seven days a week on either a part-time or full time schedule for four weeks or longer in some cases.
