Outpatient treatment gives rehab clients the ability to sustain specific obligations and aspects of their way of life while taking part in drug rehabilitation services. Outpatient treatment is a moderate level of rehabilitation, and shouldn't be mistaken for the amount of rehabilitation offered in an inpatient or residential rehab program which is much more intensive. Outpatient treatment may be suitable for anyone who has a brief history of drug abuse for example, but will almost certainly not be adequate for someone whose rehab needs exceed that which outpatient treatment is able to provide. Individuals involved in substance abuse often require an extreme environmental change, because many of the things that prompt their drug and alcohol use are purely environmental. As an example, if someone else has been physically or emotionally mistreated and this is prompting their drug or alcohol use, it's impossible for any treatment endeavours to succeed if they go back to such situations on a daily basis. In outpatient treatment, clients can take advantage of group and one-on-one therapy, as well as family therapy services. In outpatient treatment, most programs offer services six or seven days per week on either a part-time or full time basis for four weeks or longer in some instances.
