The Oregon Supreme Court unanimously ruled Thursday that a retired school bus driver can have her medical marijuana and a concealed handgun, too.

The ruling upheld previous decisions by the Oregon Court of Appeals and circuit court that determined a federal law barring criminals and drug addicts from buying firearms does not excuse sheriffs from issuing concealed weapons permits to people who hold medical marijuana cards and otherwise qualify.

"We hold that the Federal Gun Control Act does not pre-empt the state's concealed handgun licensing statute and, therefore, the sheriffs must issue (or renew) the requested licenses," Chief Justice Paul De Muniz wrote in the ruling issued in Salem.

Cynthia Willis, one of four plaintiffs, welcomed the ruling.

"I feel like a big girl now," Willis said. "I feel like a real human being now, not just a source of revenue to the county."

Leland Berger, the attorney representing Willis and other medical marijuana patients in the state, said the ruling was important in the continuing national debate over making marijuana legal to treat medical conditions.

"I am hopeful we will end cannabis prohibition the same way we ended alcohol prohibition, which was by refusing to enforce federal laws within the state," Berger said.
