The judge of any court, before whom appears an individual charged with a second or subsequent offense of public intoxication, may, upon a plea of guilty or conviction suspend execution of sentence and require the offender to participate in and complete a prescribed course of alcohol abuse treatment and rehabilitation. The judge shall consult with the division to determine the course of treatment best suited to the needs of the convicted person. The convicted person while participating in the course of treatment shall not be considered committed, civilly or criminally, as otherwise provided by law for commitment to any institution; provided that no judge may require in-patient care for a period in excess of ninety (90) days. Upon completion of the course of treatment prescribed by the judge, the sentence shall not be executed. The convicted person, if financially able, shall be responsible for defraying any cost of the prescribed course of treatment.
