Controlled Substances - As introduced, revises the definition of hemp to align with the federal definition as enacted in the Continuing Appropriations, Agriculture, Legislative Branch, Military Construction and Veterans Affairs, and Extensions Act of 2026. - Amends TCA Title 39; Title 43 and Title 57.

SB 1652 updates Tennessee's legal definition of "hemp" to match the federal standard established in the 2026 federal appropriations act. It defines hemp as Cannabis sativa L. with ≤0.3% total THC on a dry weight basis, excluding products exceeding this limit or containing synthetically produced cannabinoids. The bill clarifies that "industrial hemp" refers to non-cannabinoid uses (like fiber or seeds), while "hemp-derived cannabinoid products" include all other consumer products containing cannabinoids. This directly affects hemp growers, manufacturers, and retailers by aligning state regulations with federal law and setting clear limits on THC content and product types.
