Minnesota: Bipartisan Senate Bill Would Place Strict THC Limits on Cannabis Products

Key Points
  • A bipartisan group of Minnesota senators introduced Senate File 4434, proposing strict THC potency caps on recreational marijuana products and enhanced warning labels.
  • The bill limits marijuana flower to 15% total THC, cannabis concentrates to 30% THC, and topical or transdermal products to 500 milligrams of THC per package.
  • SF 4434 would prohibit the sale of marijuana flower and prerolls infused with extra THC or other psychoactive cannabinoids in the adult-use market.
  • The legislation mandates comprehensive warning notices on packaging and in stores about health risks, including effects on brain development, psychosis, dependence, pregnancy, impaired driving, and delayed effects of edibles.

A bipartisan group of Minnesota senators filed legislation today that would impose strict THC potency caps on recreational marijuana products while mandating a wide range of new warning notices and labeling requirements. Senate File 4434 was introduced March 12 and referred to the Commerce and Consumer Protection Committee. The measure would limit marijuana flower sold in the adult-use market to no more than 15% total THC and cap cannabis concentrates at 30% total THC. It would also restrict topical or transdermal cannabis and hemp products to 500 milligrams of total THC per package.

The proposal was filed by a group of five lawmakers (four Republican and one Democrat), giving new momentum to an issue that first surfaced last month when State Senator Matt Klein (D) filed Senate File 3591. The newly introduced measure is substantially similar to Klein’s bill, carrying over the same core THC limits, product restrictions and warning-label provisions.

In addition to the potency caps, SF 4434 would bar the sale in the adult-use market of marijuana flower and prerolls infused with additional THC or other psychoactive cannabinoids. It would also require retailers to post warnings stating, among other things, that marijuana smoke contains toxic chemicals, that higher-THC products carry greater risks of paranoia and anxiety, and that edible products can take hours to take effect.

The bill would also expand package-label requirements for marijuana and hemp products, including multiple health warnings related to brain development, psychosis, dependence, pregnancy and impaired driving.
