GRAND JUNCTION, Colo. -- Pot shops are now required by law to grow 70 percent of their own product. The question now, is how is the state going to enforce the rules?

To keep dispensaries in line the state says it all comes down to the paper trail. But dispensaries say it's a trail that will only lead to more changes.

"We had to buy more equipment more things of that nature, expand our operation a little bit," says Shawn Kizer with Nature's Medicine.

Pot shops are now stocking their shelves with mostly their product. State reps say the new law is to force grow operations and dispensaries to merge, unifying the industry.

But pot shop owners say for most of them, it isn't changing much.

We were probably right in the range of 50-percent. So it didn't take a whole lot to jump up to that 70 percent," says Kizer.

Kizer says his shop is already up to speed but wonders if his shop will have to undergo even further changes.

"It really does, how, depend on how the Department of Revenue sets up their team and how they go about it. Without us knowing those aspects of the operation then it's kind of one of those things we really don't know," says Kizer.

But Colorado's Department of Revenue says it may be awhile before they even start enforcing the rules.

"Albeit very scarce and very limited because we don't have resources. There are three of us right now," says Matt Cook with the Dept. of Revenue.

He says they're in the hiring process right now, using the pot shop application fees to fund their new hires. Once everything comes in to place they'll start cracking down.

"What ever their gross sales are, look at 70 percent of it and see if it came from their grow operations. Again their required to keep records of virtually ever business transaction that they do," says Cook.

But pot shops say it's just not that easy to track.

Some say the law is too vague and impossible to enforce. Some shops say they don't even know how the state plans to check in on them.

It's too early to really see what they need to do to comply with state law. The only certainty for some dispensaries is more change is on the way.

"I do fully expect to evolve. Depending on what they decide to do and how they decide to go about it. It just depends on their new rules and regulations they put through. We're obviously going to have to evolve to that to stay legal," says Kizer.
