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.

HB 1148 removes Tetrahydrocannabinolic acid (THCa) and Tetrahydrocannabiphorol (THCp) from the list of legally authorized hemp-derived cannabinoids in Tennessee law. This change directly affects manufacturers, distributors, and sellers of hemp products containing these compounds, as such products would no longer qualify as legal hemp under state law. The bill amends definitions to clarify that "Total THC" includes converted THCa (using a 0.877 conversion factor), and requires testing to measure potential THC after decarboxylation. Products containing THCa or THCp would now be subject to seizure and forfeiture under state law.
