Outpatient treatment gives treatment clients the opportunity to sustain certain responsibilities and aspects of their life-style while getting involved in drug and alcohol rehab services. Outpatient treatment is a moderate amount of rehab, and shouldn't be mistaken for the amount of rehabilitation offered in an inpatient or residential rehabilitation setting that is significantly more intensive. Outpatient treatment could be suited to someone who has a brief history of substance abuse for instance, 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 drug abuse often require a considerable environmental change, because many of the things which prompt their drug abuse are strictly environmental. For example, if a person has been physically or emotionally mistreated and this is triggering their substance abuse, it's impossible for any treatment efforts to have success if they go back to such circumstances every day. In outpatient treatment, individuals can engage in group and one-on-one therapy, as well as family therapy services. In outpatient treatment, most centers will provide services 5 to 7 days each week on either a part-time or full time basis for four weeks or longer in some instances.
