An online petition posted over the weekend to an activist website aims at urging the Oregon Legislature not to mess with the state's medical-marijuana program.

The petition, which appears under the logo for Oregon NORML, points to several bills in the Legislature that opponents say would undermine a program used by more than 38,000 Oregonians.

The proposed bills would further limit the amount of cannabis that cardholders can possess, ban grow sites within 2,500 feet of schools, and make it easier for law enforcement to obtain info on grow sites, among other changes.
