A lawmaker in Colorado is trying to outlaw marijuana infused gummy bears that look similar to the sweet commonly eaten by children. 

Colorado has had legal marijuana since 2014, and somewhat uniquely among legal states in the US, has no laws concerning edible sales that differ from cannabis flowers.

Dan Pabon, a State Representative for the Democrats in Denver wants to ban edible marijuana in the form of animals, humans or fruit. Essentially he wants to ban anything that looks like something a child might eat.

“Right now in Colorado, there are no distinguishing characteristics between the gummy bear that contains marijuana and one that does not,” Palon said.

The appeal of edible marijuana products to children has become a concern in the few U.S. states that have legalized pot in recent years.

In Washington state, where legal pot has been on sale for about 18 months, regulators recently tightened the rules on edible products made with cannabis, said Rick Garza, director of the Washington State Liquor and Cannabis board.

The new restrictions outlawed brightly colored marijuana lollipops and other sweets deemed to be particularly attractive to children, Gar said.

Several children have been sent to hospital in Colorado after ingesting marijuana infused products after legalization, prompting the need for a new look at the recently passed legislation.

But Democratic Governor John Hickenlooper has urged the legislature to do more, saying in his State of the State address in January that pot-laced edibles look too much like “products kids can find in the candy aisle.”

“Back in the day, candy cigarettes desensitized kids to the dangers of tobacco – and today, pot-infused gummy bears send the wrong message to our kids about marijuana,” Hickenlooper said.

Pabon’s bill, submitted on Thursday, directs the state’s marijuana regulatory agency to develop more detailed guidelines on how enforcing the ban on marijuana candies shaped like humans, animals or fruit would work.
