Does anyone enforce rules about the smell of medical marijuana?

PORTLAND, Ore. - A Southeast Portland couple says their neighbors' medical marijuana plants are making them sick, and they want the city to step in and do something about it.

KATU News got a large response from viewers and readers to our first story about the Petersons.

"They're too close. They're way too close for this to be happening," Gloria Peterson told KATU last week. "There needs to be some sort of zoning regulation that there has to be some sort of distance, I believe, between a marijuana grow and a neighbor."

So what can they do about it? Does anyone in Oregon enforce rules about the smell of medical marijuana?

The answer, as far as we can tell, is no.

Portland Police, city hall, the Department of Environmental Quality and Multnomah County Health Department all said on Monday that they couldn't do anything about it.

There is a "noisome odors or vapors" ordinance in Chapter 8, Section 36 of Portland City Code. It says "No person shall burn upon any premises or in any street, alley or other place, any animal or vegetable substance which shall create an offensive or noxious odor."

KATU called police about that city rule. They sent us to City Hall, who then sent us to the Multnomah County Health Department. A spokesperson said their inspectors investigate stinky smells, but not marijuana. The county health department sent us right back to police.

About 53,000 people carry medical marijuana cards in Oregon.
