No edible cannabis product can be sold in Colorado unless the product and the container are marked with the required universal symbol, as of November 30, 2016.
Non-medical cannabis products must be marked per 10 mg THC serving; if the product cannot be marked per serving, then the package can only contain one serving. In the case of liquid non-medical edibles, like a cannabis-infused drink, one container can have 100 mg THC, but the container should be manufactured in a way to dispense servings of 10 mg or fewer.
Medical cannabis edible products must also be marked with a universal symbol. If a medical cannabis edibles product manufacturer chooses to create servings (they don’t have to), then each portion must also be marked with the symbol.
Also, as of October 1, when the above rules go in effect (with a two-month window to comply), no cannabis edibles package can include the words “candy” or “candies,” since those would appeal to children.
Ensuring cannabis edibles do not appeal to kids is an increasing concern in states that have legalized cannabis for non-medical use. In Oregon, officials will soon create a list of forbidden cannabis strain names, like Grape Ape, that would be attractive to children and teenagers.
Colorado has come a long way with cannabis edibles since sales began in January 2014. Initially, the state did not limit how much THC could be in a serving, or require that servings be somehow individually marked. Though, edibles quickly rose in popularity, and there were some high profile overdoses, including a college student who jumped to his death. New York Times columnist Maureen Dowd, who wrote about her bad trip after eating cannabis-infused chocolate, also sparked a lengthy debate about edibles labeling and education.
“With the new universal symbol, people can more easily identify marijuana products, monitor their intake by serving size and avoid eating too much,” said Dr. Larry Wolk, executive director and chief medical officer at the Colorado Department of Public Health and Environment, in a statement.
