In making a determination regarding a substance, the State Board of Health shall consider all of the following:

(1) The actual or relative potential for abuse.

(2) The scientific evidence of its pharmacological effect, if known.

(3) The state of current scientific knowledge regarding the substance.

(4) The history and current pattern of abuse.

(5) The scope, duration, and significance of abuse.

(6) The risk to the public health.

(7) The potential of the substance to produce psychic or physiological dependence liability.

(8) Whether the substance is an immediate precursor of a substance already controlled under this chapter.

(b) After considering the factors enumerated in subsection (a), the State Board of Health shall make findings with respect thereto and issue a rule controlling the substance if it finds the substance has a potential for abuse.

(c) If any substance is designated, rescheduled, or deleted as a controlled substance under federal law and notice thereof is given to the State Board of Health, the State Board of Health shall similarly control the substance under this chapter after the expiration of 30 days from publication in the federal register of a final order designating a substance as a controlled substance or rescheduling or deleting a substance, unless within that 30-day period, the State Board of Health objects to inclusion, rescheduling, or deletion. In that case, the State Board of Health shall publish the reasons for objection and afford all interested parties an opportunity to be heard. At the conclusion of the hearing, the State Board of Health shall publish its decision, which shall be final unless altered by statute. Upon publication of objection to inclusion, rescheduling, or deletion under this chapter by the State Board of Health, control under this chapter is stayed until the State Board of Health publishes its decision.

(d) Authority to control under this section does not extend to distilled spirits, wine, malt beverages, or tobacco.

(e) The State Board of Health shall exclude any nonnarcotic substance from a schedule if such substance, under the federal Food, Drug and Cosmetic Act, the federal Comprehensive Drug Abuse Prevention and Control Act of 1970, and the law of this state may be lawfully sold over the counter without a prescription.
