BOISE (KTVB) -- Those in the western Treasure Valley and across Oregon have voted to legalize marijuana.

Measure 91 passed Tuesday night, and now both of Idaho's western neighbors have legalized recreational pot.

Oregon already had access to medicinal marijuana, so law enforcement said they had seen a little change from that. They expect that's only a preview of what could come with recreational pot.

Those in western Idaho towns like Fruitland already take advantage of Oregon laws. Many drive across the border for tax free shopping, but Measure 91 could create another reason to go to Oregon.

Law enforcement says bringing back marijuana into Idaho is not welcome

"With that recreational ballot measure passing there could be a significant upswing in the use of marijuana," said JD Huff, a Fruitland native and the Chief of Police. While Oregon is changing, his department won't be.

"We don't have to make any adjustment over here to our code enforcement. We'll continue to enforce criminal code," said Huff.

Huff said there's simply not enough manpower to catch everyone who might traffic newly-legalized marijuana out of Oregon and into Idaho. Fruitland Police have ten full-time officers and one canine.

"It would be naive to think that we can stop all of the drugs that are coming through this community. We're right here on Highway 95, it's a great pipeline from I-84 off the interstate and we have Oregon right next door," said Huff. "We'd be naive to think that it wasn't coming over here."

Huff said traffic stops usually lead to their drug arrests, so they are vigilant in Fruitland about traffic violations. He says law enforcement in the western Treasure Valley will work together and talk to cities on the Oregon and Washington border as well.
