OLYMPIA — Washington officials say they plan to require a new “Not For Kids” label on edible marijuana products sold at the state’s legal pot shops.

The symbol, chosen by the Washington Poison Center, features a bright red hand held up in a “stop” gesture, accompanied by the words “Not For Kids” with an emergency number to call.

Dr. Alexander Garrard, the poison center’s managing director, says the center has received more than 150 calls about marijuana exposure so far this year.

Washington’s Liquor and Cannabis Board initially said it would require a “Mr. Yuk” sticker on pot products to deter children from accidentally ingesting them. That drew objections from some marijuana producers and retailers. The board says the new symbol was developed with their input as well as suggestions from prevention specialists.

The board expects the label to be required beginning next January.
