Wondering if that brownie contains pot? Colorado has you covered.
A requirement 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 — takes effect Saturday.
The rule referencing marijuana’s psychoactive ingredient was added after complaints that the treats look too much their non-intoxicating counterparts. It is the first such requirement in any legal weed state.
