Colorado could crack down again on marijuana edibles as state lawmakers begin debate Tuesday on a bill to ban certain shapes of pot products.

When Colorado voted to legalize pot, the state also legalized concentrated "marijuana products." Today. Colorado has products in all sorts of shapes.

“I've got a three year-old that can't tell the difference between a gummy bear that contains marijuana and one that doesn't,” said Rep. Dan Pabon (D-Denver).

Pabon, who started work on this issue before his arrest for DUI last month, is pushing to pass HB 1436, which would ban certain forms of edibles that resemble a "human, animal or fruit.”

There are all kinds of edibles being sold right now in Colorado that might be quickly banned under a law like this. Gummy worms, gummy bears, and fruit wedge candies can all be found in Colorado marijuana shops.

After Gov. John Hickenlooper made the issue a priority in this year’s State of the State address, some in the marijuana industry attempted to fend off a new law on this issue by adopting voluntary standards against edibles shaped like people or animals.

Now that they’re staring at a bill to impose that as a legal requirement, the pot industry argues a ban on broad types of shapes is over-the-top.

“This truly, in my opinion, is an attack on marijuana,” said Dan Anglin with Boulder-based edibles maker Americanna.

He points out the state just came up with a mandatory logo. A diamond shape containing the letters “THC” has to be stamped or printed on all edibles starting this fall.

“We don't think we need a law before this other law even kicks in,” Anglin said.

The new logo is already printed on a new candy his company makes, which is shaped like a pot leaf.

That shape raises his other concern State regulators would get to decide: Does that really look like a pot leaf? Or is it really a fruit or an animal?

“It could certainly be misconstrued as a starfish, or the top of a pineapple,” Anglin said of his new product.

Pabon says those fears are overblown.

“We have enough common sense in the rulemaking process to allow for catching those items that fit into those categories and allowing other items to continue to exist on the market,” Pabon said.

HB 1436 gets its first public hearing at 1:30 p.m. Tuesday in the House business affairs committee.
