A sampling of rules for retail sales of recreational marijuana in Colorado. The rules were released Monday, but retail sales don't start until January.
— No single package of an edible marijuana product can contain more than 100 milligrams of active THC, no matter how many servings it contains.
— Colorado residents can buy up to an ounce of marijuana at a time. Out-of-state residents can buy up to a quarter-ounce.
— Labels on marijuana-laced snacks have to list their ingredients and carry warnings including "The intoxicating effects of this product may be delayed by two or more hours."
— Licensed growers can't sell to consumers. Marijuana can't be consumed at a cultivation site.
— Waste marijuana has to be "unusable and unrecognizable" when discarded. One method: It can ground up with an equal amount of paper, cardboard, plastic, food waste or grease.
— Testing facilities have to destroy the marijuana after they test it.
— Sheriffs, deputies, police officers and some other state officials can't get a marijuana retail license.
— Licensed retailers have to have video surveillance systems and commercial-grade locks.
— Retailers and their employees must wear identification badges issued by the Colorado Department of Revenue.
