SB 602 Michigan Senate · 2025-2026 Regular Session

Marihuana: other; references to and regulation of industrial hemp under the Michigan Regulation and Taxation of Marihuana Act; amend. Amends secs. 3 & 8 of 2018 IL 1 (MCL 333.27953 & 333.27958). TIE BAR WITH: SB 0599'25

SB 602 amends Michigan's Marihuana Regulation Act to clarify the legal definition of "industrial hemp" under Sections 3 and 8. It specifies that industrial hemp must contain 0.3% THC or less on a dry-weight basis and explicitly includes hemp-derived products meeting this threshold. This update directly affects hemp producers, processors, and retailers who must comply with these THC limits for products like seeds, oils, and hemp-based consumer goods. The bill refines existing regulatory language to align with federal standards without creating new licensing or tax requirements.
