This chapter does not apply to a person being treated by a physician for a substance use disorder because of the person's use of controlled substances not related to treatment for pain. This chapter does not authorize a physician to prescribe or administer any drug legally classified as a controlled substance or as an addictive or dangerous drug for other than medically accepted therapeutic purposes. A person to whom controlled substances are prescribed or administered for pain is not exempt from section 39-08-01 or 39-20-04.1.
