Jackson County Sheriff Mike Winters has appealed to the U.S. Supreme Court in his latest bid to block issuing concealed handgun licenses to medical marijuana users.

Winters has asserted that he can't issue the concealed handgun license because it would violate federal law, specifically the Gun Control Act of 1968.

The sheriff's legal argument has been shot down by every court so far, including the Jackson County Circuit Court, the Oregon Court of Appeals and the Oregon Supreme Court.

Cynthia Townsley Willis, who uses cannabis for muscle spasms and arthritis pain and has a clean criminal record, admitted to using medical marijuana when she filed her application with the sheriff for a concealed handgun license in 2008. The sheriff denied her application, claiming that her possession of a medical marijuana card indicated she was a drug user. Willis has a concealed weapon's license, which Winters approved after the Oregon Court of Appeals ruled against him.
