Summary

This bill would narrow Wisconsin’s definition of hemp, limiting it to plants with no more than 0.3% total THC and banning products made with synthetic or lab-altered cannabinoids such as delta-8 THC. It keeps traditional uses of hemp—like fiber, seed oil, and research—legal but would make many popular hemp-derived products currently sold in Wisconsin shops illegal to sell or possess.
