11401.  

(a) A controlled substance analog shall, for the purposes of Chapter 6 (commencing with Section 11350), be treated the same as the controlled substance classified in Section 11054 or 11055 or the synthetic cannabinoid compound defined in Section 11357.5 of which it is an analog.

(b) Except as provided in subdivision (c), the term “controlled substance analog” means either of the following:

(1) A substance the chemical structure of which is substantially similar to the chemical structure of a controlled substance classified in Section 11054 or 11055 or a synthetic cannabinoid compound defined in Section 11357.5.

(2) A substance that has, is represented as having, or is intended to have a stimulant, depressant, or hallucinogenic effect on the central nervous system that is substantially similar to, or greater than, the stimulant, depressant, or hallucinogenic effect on the central nervous system of a controlled substance classified in Section 11054 or 11055 or a synthetic cannabinoid compound defined in Section 11357.5.

(c) The term “controlled substance analog” does not mean any of the following:

(1) A substance for which there is an approved new drug application as defined under Section 505 of the federal Food, Drug, and Cosmetic Act (21 U.S.C. Sec. 355) or that is generally recognized as safe and effective for use pursuant to Sections 501, 502, and 503 of the federal Food, Drug, and Cosmetic Act (21 U.S.C. Secs. 351, 352, and 353) and Section 330 and following of Title 21 of the Code of Federal Regulations.

(2) With respect to a particular person, a substance for which an exemption is in effect for investigational use for that person under Section 505 of the federal Food, Drug, and Cosmetic Act (21 U.S.C. Sec. 355), to the extent that the conduct with respect to that substance is pursuant to the exemption.

(3) A substance, before an exemption as specified in paragraph (2) takes effect with respect to the substance, to the extent the substance is not intended for human consumption.
