Known as hash oil, wax, dabs, and shatter, concentrates deliver a high so fast and intense many users refer to them as “green crack.” One ounce of the highest potency THC concentrate can yield 560 average tokes on an electronic cigarette. In edibles, Colorado law defines an average serving of THC as 10 milligrams.

The 10-milligram serving size established by Colorado lawmakers means one 1 ounce of high-potency THC oil — the amount one adult is allowed to buy or possess at any given time — also can equal 2,800 average servings. That’s a well-stocked bakery.

Edibles make up about 45 percent of Colorado’s marijuana sales, based on state figures, and are projected to quickly surpass the sale of THC products that are smoked.
