Outpatient treatment gives treatment clients the ability to sustain certain obligations and elements of their lifestyle while getting involved in drug and alcohol rehab services. Outpatient treatment is a moderate amount of treatment, and should not be mistaken for the degree of treatment offered in an inpatient or residential rehabilitation program that is significantly more intensive. Outpatient treatment may be ideal for anyone who has a brief history of drug abuse for example, but will certainly not be adequate for an individual whose treatment needs exceed that which outpatient treatment is able to offer. Individuals involved in drug abuse often require a considerable environmental change, because many of the things which trigger their drug and alcohol use are strictly environmental. For instance, if a person is being physically or emotionally mistreated and this is triggering their drug abuse, there is no way for any rehabilitation efforts to have success whenever they return to such conditions every day. In outpatient treatment, individuals can engage in group and one-on-one therapy, in addition to family therapy services. In outpatient treatment, most centers offer services five to seven days each week on either a part time or full-time basis for thirty days or longer in some instances.
