Concentrated marijuana under review in Colorado

When people buy marijuana from a store in Colorado, the ounce they can walk out the door with is fairly easy to measure. Not so when the pot is in concentrated form, perhaps baked into a cookie or brownie.

Colorado may change that. A bill pending in the state House would direct Colorado’s pot regulators to determine how much concentrated pot is equal to an ounce of leafy pot.

Washington state, the only other state with legal recreational pot, already has limits of less than an ounce for hash oil. In Colorado, the law is murky.

The marijuana amendment approved by Colorado voters in 2012 doesn’t clarify any difference between leafy pot and oils used to make marijuana-infused cookies or other edibles.
