Revise drug laws to regulate THC levels

This bill amends Montana's drug laws to set maximum THC concentration limits and package size restrictions for marijuana products sold at dispensaries. It directly affects dispensary operators, consumers, and medical marijuana cardholders by establishing new rules on what products can be sold and in what quantities. The key provisions limit total THC in any product to 15%, cap flower sales at 15% THC, and restrict single-serving edibles to 10 milligrams of THC while maintaining an 800-milligram package limit for most products. Medical marijuana cardholders would still be able to purchase higher-THC products, while adult-use consumers would be subject to the lower potency limits. The bill also authorizes the state department to adopt rules for inspecting dispensaries and establishing these THC content limits.
