No person shall unlawfully use or be addicted to the unlawful use of any controlled substance. Any such unlawful use or addiction shall be deemed a violation of this section. Any nonmedical habitual user of a controlled substance, as defined in § 131.04, who shall make voluntary application to the judge of the district court may, upon the presentment of a certificate executed by a practicing physician in the State of Michigan stating that he or she is a nonmedical habitual user of a controlled substance, be committed, at the discretion of the court, to any correctional or charitable institution, hospital, sanitarium or institution authorized for the treatment of disease or inebriety or drug addiction. Whenever the medical officer or head of such institution shall certify to the committing judge or court that any person so committed has been sufficiently treated or gives any other reason which is deemed by such judge or court to be adequate and sufficient, the court may, in accordance with the terms of commitment, discharge the person so committed or return him or her to await further action of the court. Any addicted person who does not make voluntary application for treatment as provided in this section shall be deemed to be in violation of this section.
