Alaska Marijuana Control Board is considering doubling the amount of THC allowed in edibles Published March 2 Share on Facebook Print article Alaska marijuana regulators are considering loosening restrictions on edible marijuana products in the state. The regulation change would double the amount of THC, the plant’s psychoactive compound, allowed in a single serving. Proponents of the change say it would benefit the industry, giving manufacturers more flexibility and saving money for them and for consumers. Alaska’s limit on edibles is currently the strictest compared with other states where recreational marijuana is legal, and some states allow much higher doses.
