“A federal appeals court has ruled that an existing federal ban on the sale of guns to holders of medical marijuana cards does not violate the Second Amendment of the U.S. Constitution, which prohibits infringement of the right to keep and bear arms. The ruling pertains to the nine states under the jurisdiction of the 9th U.S. Circuit Court of Appeals: Alaska, Arizona, California, Hawaii, Idaho, Montana, Nevada, Oregon, and Washington. Of those nine, only Idaho hasn’t legalized medical marijuana, which, as far as the federal government is concerned, remains illegal everywhere in the U.S. regardless of state laws.

The specific case was a lawsuit brought by a Nevada plaintiff, S. Rowan Wilson, who said a gun store refused to sell her a weapon after she obtained a medical marijuana card in 2011. At issue was the assumption that possession of such a card is reasonable cause to presume that the holder actually uses the drug (Wilson claims she doesn’t). The appeals court ruled that it is, in fact, an “eminently reasonable” assumption.
