Controlled Substances - As introduced, removes Tetrahydrocannabinolic acid (THCa) and Tetrahydrocannabiphorol (THCp) from the list of authorized hemp-derived cannabinoids. - Amends TCA Title 39, Chapter 17, Part 4 and Title 43, Chapter 27.

SB 1236 removes Tetrahydrocannabinolic acid (THCa) and Tetrahydrocannabiphorol (THCp) from the list of authorized hemp-derived cannabinoids under Tennessee law. It amends definitions to clarify that "Total THC" calculations exclude THCa (using a conversion factor) and explicitly prohibits products containing these substances. This bill directly affects hemp product manufacturers, retailers, and distributors who would need to reformulate or remove products containing THCa or THCp to comply. The legislation also requires state testing to verify cannabinoid profiles using post-decarboxylation methods to determine legal THC limits.
