Indiana Code Title 35. Criminal Law and Procedure § 35-48-2-14

Sec. 14. (a) The board may adopt rules under IC 4-22-2 to reclassify a controlled substance:

if the board finds that the substance qualifies for reclassification under this chapter and that the same reclassification has been made in a controlled substance schedule under federal law.

(b) If the board reclassifies a controlled substance under subsection (a), the board shall recommend the same reclassification to the general assembly under section 1 of this chapter.

(c) Notwithstanding a provision in this chapter that classifies a controlled substance in a more restrictive schedule than a rule adopted under subsection (a), a person who manufactures, distributes, dispenses, possesses, or uses a controlled substance in compliance with the requirements applicable to the less restrictive schedule to which a controlled substance is reclassified under subsection (a) does not commit an offense under this article.

(d) Notwithstanding a provision in this chapter that classifies a substance as a controlled substance, a person does not commit an offense under this article if the board has reclassified the controlled substance as a substance that is not a controlled substance.
