IC 35-31.5-2-321
.

IC 35-48-1.1-8
“Controlled substance analog”
     
Sec. 8. (a) “Controlled substance analog” means a
substance that, due to its chemical structure and potential for abuse or
misuse, meets the following criteria:
(1) The substance is substantially similar to a controlled substance
classified under
IC 35-48-2
.
(2) The substance has a narcotic, stimulant, depressant, or
hallucinogenic effect on the central nervous system or is
represented or intended to have a narcotic, stimulant, depressant,
or hallucinogenic effect on the central nervous system
substantially similar to or greater than that of a controlled
substance classified under
IC 35-48-2
.
     
(b) The definition set forth in subsection (a) does not include:
(1) a controlled substance;
(2) a legend drug;
(3) a substance for which there is an approved new drug
application;
(4) any compound, mixture, or preparation that contains any
controlled substance, that is not for administration to a human
being or an animal, and that is packaged in a form or
concentration, or with adulterants or denaturants, such that as
packaged it does not present any significant potential for abuse;
(5) a substance to which an investigational exemption applies
under Section 505 of the federal Food, Drug and Cosmetic Act
(chapter 675, 52 Stat. 1052 (21 U.S.C. 355)), but only to the
extent that conduct with respect to the substance is pursuant to the
exemption; or
(6) low THC hemp extract.
     
(c) For purposes of subsection (a), “substantially similar”, as it
applies to the chemical structure of a substance, means that the
chemical structure of the substance, when compared to the structure of
a controlled substance, has a single difference in the structural formula
that substitutes one (1) atom or functional group for another, including:
(1) one (1) halogen for another halogen;
(2) one (1) hydrogen for a halogen;
(3) one (1) halogen for a hydrogen; or
(4) an alkyl group added or deleted:
(A) as a side chain to or from a molecule; or
(B) from a side chain of a molecule.
As added by P.L.186-2025, SEC.249.

(d) If any substance is designated or rescheduled to a more
restrictive schedule as a controlled substance under federal law and
notice is given to the board, the board shall recommend similar control
of the substance under this article in the board's report to the general
assembly, unless the board objects to inclusion or rescheduling. In that
case, the board shall publish the reasons for objection and afford all
interested parties an opportunity to be heard.

(1) A substance containing one (1) or more of the following
chemical compounds, including an analog of the compound:

IC 35-48-1.1-8“Controlled substance analog” Sec. 8. (a) “Controlled substance analog” means a
substance that, due to its chemical structure and potential for abuse or
misuse, meets the following criteria:
(1) The substance is substantially similar to a controlled substance
classified under IC 35-48-2.
(2) The substance has a narcotic, stimulant, depressant, or
hallucinogenic effect on the central nervous system or is
represented or intended to have a narcotic, stimulant, depressant,
or hallucinogenic effect on the central nervous system
substantially similar to or greater than that of a controlled
substance classified under IC 35-48-2.
(b) The definition set forth in subsection (a) does not include:
(1) a controlled substance;
(2) a legend drug;
(3) a substance for which there is an approved new drug
application;
(4) any compound, mixture, or preparation that contains any
controlled substance, that is not for administration to a human
being or an animal, and that is packaged in a form or
concentration, or with adulterants or denaturants, such that as
packaged it does not present any significant potential for abuse;
(5) a substance to which an investigational exemption applies
under Section 505 of the federal Food, Drug and Cosmetic Act
(chapter 675, 52 Stat. 1052 (21 U.S.C. 355)), but only to the
extent that conduct with respect to the substance is pursuant to the
exemption; or
(6) low THC hemp extract.
(c) For purposes of subsection (a), “substantially similar”, as it
applies to the chemical structure of a substance, means that the
chemical structure of the substance, when compared to the structure of
a controlled substance, has a single difference in the structural formula
that substitutes one (1) atom or functional group for another, including:
(1) one (1) halogen for another halogen;
(2) one (1) hydrogen for a halogen;
(3) one (1) halogen for a hydrogen; or
(4) an alkyl group added or deleted:
(A) as a side chain to or from a molecule; or
(B) from a side chain of a molecule.
As added by P.L.186-2025, SEC.249.

(g) Synthetic drugs as defined in IC 35-31.5-2-321.
