(15) “Controlled substance” means a drug, substance, or immediate precursor included in Schedules I through V as set forth in federal or state laws, or federal or commission rules, but does not include hemp or industrial hemp as defined in RCW
15.140.020
.
(16)(a) “Controlled substance analog” means a substance the chemical structure of which is substantially similar to the chemical structure of a controlled substance in Schedule I or II and:
(i) that has a stimulant, depressant, or hallucinogenic effect on the central nervous system substantially similar to the stimulant, depressant, or hallucinogenic effect on the central nervous system of a controlled substance included in Schedule I or II; or
(ii) with respect to a particular individual, that the individual represents or intends to have a stimulant, depressant, or hallucinogenic effect on the central nervous system substantially similar to the stimulant, depressant, or hallucinogenic effect on the central nervous system of a controlled substance included in Schedule I or II.
(b) The term does not include:

(d) [(4)] If a substance is designated, rescheduled, or deleted as a controlled substance under federal law, the commission shall similarly control the substance under this chapter after the expiration of thirty days from the date of publication in the federal register of a final order designating the substance as a controlled substance or rescheduling or deleting the substance or from the date of issuance of an order of temporary scheduling under Section 508 of the federal Dangerous Drug Diversion Control Act of 1984, 21 U.S.C. Sec. 811(h), unless within that thirty-day period, the commission or an interested party objects to inclusion, rescheduling, temporary scheduling, or deletion. If no objection is made, the commission shall adopt and cause to be published, without the necessity of making determinations or findings as required by subsection (a) [(1)] of this section or RCW
69.50.203
,
69.50.205
,
69.50.207

If an objection is made, the commission shall make a determination with respect to the designation, rescheduling, or deletion of the substance as provided by subsection (a) [(1)] of this section. Upon receipt of an objection to inclusion, rescheduling, or deletion under this chapter by the commission, the commission shall publish notice of the receipt of the objection, and control under this chapter is stayed until the commission adopts a rule as provided by subsection (a) [(1)] of this section.
(e) [(5)] The commission, by rule and without regard to the requirements of subsection (a) [(1)] of this section, may schedule a substance in Schedule I regardless of whether the substance is substantially similar to a controlled substance in Schedule I or II if the commission finds that scheduling of the substance on an emergency basis is necessary to avoid an imminent hazard to the public safety and the substance is not included in any other schedule or no exemption or approval is in effect for the substance under Section 505 of the federal Food, Drug, and Cosmetic Act, 21 U.S.C. Sec. 355. Upon receipt of notice under RCW
69.50.214
, the commission shall initiate scheduling of the controlled substance analog on an emergency basis pursuant to this subsection.

With respect to the finding of an imminent hazard to the public safety, the commission shall consider whether the substance has been scheduled on a temporary basis under federal law or factors set forth in subsection (a)(1) [(1)(a)](iv), (v), and (vi) of this section, and may also consider clandestine importation, manufacture, or distribution, and, if available, information concerning the other factors set forth in subsection (a)(1) [(1)(a)] of this section. A rule may not be adopted under this subsection until the commission initiates a rule-making proceeding under subsection (a) [(1)] of this section with respect to the substance. A rule adopted under this subsection must be vacated upon the conclusion of the rule-making proceeding initiated under subsection (a) [(1)] of this section with respect to the substance.
