An individual may ask voluntarily for admission to an outpatient treatment program, whether or not the individual has been admitted to the program before. After an individual asks for admission to an outpatient treatment program, the administrative head of the program shall determine whether the individual is to be admitted. However, the administrative head may not deny readmission of an individual solely because the individual previously left the program against the advice of the administrative head. An outpatient treatment program shall use public and private community efforts, including welfare services, vocational rehabilitation, and job replacement, to integrate a chronic alcoholic into society as a productive citizen. A chronic alcoholic may not be dropped from an outpatient treatment program solely because of a relapse into intoxication. Every reasonable method of treatment shall be used to prevent a relapse. If recovery of the chronic alcoholic is unlikely, the outpatient treatment program shall provide supportive services and residential facilities so that the individual may survive in a decent manner.
