In Southern Oregon, commissioners in Jackson County have been fielding complaints about medical marijuana grows -- traffic, lights and the skunk-like smell of maturing pot.

The county commissioners say a new state law designed to put medical marijuana dispensaries on a sound legal footing could lead to more pot grows.

But their county administrator, Danny Jordan, tells them that trying to pass nuisance laws against marijuana grows could run up against Oregon's right-to-farm laws: Regulations on pot grows would apply to other crops.

For instance, the Medford Mail Tribune reports an onion crop has a strong odor, and grain farmers use lights to work their fields after sundown.

The right-to-farm law is designed to protect the normal practices of agriculture, especially where new residential development abuts farm land.
