Outpatient treatment gives rehab clients the opportunity to maintain certain responsibilities and elements of their life-style while taking part in alcohol and drug rehab services. Outpatient treatment is a moderate level of rehabilitation, and should not be mistaken for the level of treatment offered within an inpatient or residential rehabilitation setting which can be much more extensive. Outpatient treatment might be ideal for someone who has a brief history of substance abuse as an example, but will most definitely not be sufficient for an individual whose treatment needs exceed that which outpatient treatment is able to offer. Individuals involved in drug abuse often need a considerable environmental change, because many of the things that trigger their drug and alcohol use are strictly environmental. For instance, if someone else has been 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 go back to such situations on a daily basis. In outpatient treatment, clients can take advantage of group and one-on-one counseling, along with family therapy services. In outpatient treatment, most programs will provide services 5 to 7 days per week on either a part time or full-time basis for four weeks or longer in some instances.
