The FDA has warned the makers of popular "relaxation brownies" that contain melatonin to stop baking them. Melatonin has not been deemed a safe food additive, says the FDA. As WFAE and NPR have previously reported, Lazy Cakes (recently renamed Lazy Larry brownies) are marketed as a safe, legal way to relax. People who've eaten them say the effect is more like a sleeping pill than a "pot brownie." The FDA says it can seize the brownies, which it considers adulterated, if the company keeps making and selling them.
