Bills setting restrictions on marijuana edibles in Colorado have cleared the state House unanimously. The bills approved yesterday would set possession limits for concentrated forms of marijuana such as hash oil. Currently, Colorado adults can possess up to an ounce of marijuana without regard to whether it’s leafy flowers or concentrated oils. In its concentrated form, an ounce of pot has far more servings than the same amount in plant form. The bill directs the state Department of Revenue to determine how much concentrated pot is equal to an ounce of leafy pot. Another bill would broaden a ban on certain types of edibles to include products that mimic other foods or candies. Lawmakers are trying to prevent accidental ingestions by children. The bills now head to the Senate.
