Substitute Bill No. 970, effective July 1, 2025, revises the definition of "marijuana" in section 21a-240 of the general statutes by repealing subdivisions (29) to (62) and introducing a new definition that explicitly excludes certain hemp products. The new language clarifies that "marijuana" does not include mature stalks, seeds, and specific hemp products defined in section 22-61l, which are characterized by a total THC concentration of no more than three-tenths percent on a dry-weight basis. The bill also removes references to high-THC hemp products from the marijuana definition, thereby emphasizing the distinction between marijuana and hemp products based on THC concentration and regulatory frameworks.

Additionally, the bill introduces new definitions and amendments related to controlled substances and hemp products, including terms like "naturally manufactured hemp cannabinoid" and "synthetic cannabinoid." It updates the regulatory framework for the production, distribution, and sale of hemp products, requiring manufacturers to adhere to specific testing and disposal protocols. The bill mandates that all hemp products must pass compliance tests before sale and prohibits health claims in advertising. It also establishes labeling requirements, including total THC content and expiration dates, while ensuring that hemp products are tracked throughout the manufacturing process. Overall, the bill aims to modernize the legal landscape for hemp and cannabis products in Connecticut, ensuring compliance with state and federal regulations while enhancing consumer protection.
