Wyo. Stat. Ann. § 35-7-1011
(a) The commissioner shall administer this act and with the advice of the advisory board established in W.S. 35-7-1005 may add substances to or delete or reschedule all substances
enumerated in the schedules in W.S. 35-7-1014, 35-7-1016, 35-7-1018, 35-7-1020 and 35-7-1022 pursuant to the procedures of the Wyoming Administrative Procedure Act. In making a determination regarding a substance, the commissioner shall consider the following:
(b) After considering factors enumerated in subsection (a) of this section, the commissioner shall make findings with respect thereto and issue a rule controlling the substance if he finds the substance has a potential for abuse.
(c) If the commissioner designates a substance as an immediate precursor, substances which are precursors of the controlled precursor shall not be subject to control solely because they are precursors of the controlled precursor.
(d) If any substance is designated, rescheduled, or deleted as a controlled substance under federal law the commissioner shall control the substance under this act in the same manner as federal law within thirty (30) days after receiving notice of the change but not later than thirty (30) days after the first publication of the change in the Federal Register. Under this subsection, the commissioner shall control the substance in the same manner as federal law through the
promulgation of an emergency rule, followed by promulgation of a permanent rule under the Wyoming Administrative Procedure Act. If the commissioner objects to the designation, rescheduling or deletion of a substance, the commissioner shall within the same period required to control the substance publish the reasons for objection and afford all interested parties an opportunity to be heard. At the conclusion of the hearing, the commissioner shall publish his decision which shall be final unless altered by statute. Upon publication of an objection to designation, rescheduling or deletion under this act by the commissioner, control under this act is stayed until the commissioner publishes his final decision. Any final decision that ultimately controls the substance under this act in the same manner as federal law shall be finalized through the promulgation of an emergency rule, followed by promulgation of a permanent rule under the Wyoming Administrative Procedure Act.
(e) Authority to control under this section does not extend to distilled spirits, wine, malt beverages, or tobacco.
(f) The commissioner shall exclude any nonnarcotic substance from a schedule if such substance may under the Federal Food, Drug and Cosmetic Act, 21 U.S.C. § 301 et seq., and W.S. 33-24-131 of the Wyoming Pharmacy Act, be lawfully sold over the counter without a prescription.
