And then there’s the worst kind of delta, the Tri-Delts.

Delta-8 sales are effectively illegal in Michigan, starting today, along with a group of new laws passed earlier this year in the Michigan legislature. According to an email notice sent out by the state’s Marijuana Regulatory Agency, effective today, “it is illegal for businesses to manufacture, possess, transfer, inventory, sell, or give away delta-8 THC or THC-O-acetate without proper licensing and approval from the MRA.”

Delta-8, an isomer and cannabinoid similar to the more commonly available delta-9 THC, has become widely available in gas stations, head shops, and in underground sales. Although there has been little scientific research into the cannabinoid, many users report it to be more mellowing that delta-9. 

“There are lots of home chemists trying to skirt the federal schedule,” Greg Michaud, CEO of Viridis Laboratories, told Grown In last May. “Now we’re starting to get to some really sophisticated processing of this plant. It’s unknown where it can take us.”

Other new laws taking effect include a prohibition on licensees selling cannabis to visibly intoxicated persons. Individuals harmed by such an intoxicated person who bought cannabis from a dispensary, are now allowed to sue that dispensary. In addition, Marijuana retailers and marijuana microbusiness licensees are required to have and maintain a minimum of $50,000 of marijuana liability insurance.
