A new rule takes effect in Colorado Saturday, requiring that edible marijuana products come with a diamond-shaped stamp and the letters T-H-C — not just on the packaging but on the brownies, candies and other edibles themselves.
The rule referencing marijuana’s psychoactive ingredient (tetrahydrocannabinol or THC) was added after complaints that the treats look too much their non-intoxicating counterparts. It is the first such requirement in any state with legal weed.
The stamping requirement comes in addition to extensive labeling and packaging rules that include childproof zippers and lids, along with warnings that the product should be kept away from children and not eaten before driving or while pregnant or nursing.
“We want to ensure that people genuinely know the difference between a Duncan Hines brownie and a marijuana brownie, just by looking at it,” said state Rep. Jonathan Singer, a Democrat who sponsored the law requiring stamped edibles.
Andrew Schrot, founder of BlueKudu, a company which makes marijuana-infused chocolates, said that when he started his company in 2011 for medical marijuana customers, his pot treats looked like any other chocolate bars. But he said the switch to a recreational market in which new marijuana users were trying his products necessitated change.
