Because it can make them “irrational and unpredictable.”
If you have a medical marijuana card, the 9th U.S. Circuit Court of Appeals says that you can’t buy a gun.
The court ruled 3-0 on Wednesday that a ban preventing medical marijuana card holders from purchasing firearms is not in violation of the Second Amendment, the Associated Press reports. There are nine western states under the appeals court’s jurisdiction, including Nevada, where the case originated.
A lawsuit was filed in 2011 by Nevada resident S. Rowan Wilson after she tried to purchase a gun for self-defense and was denied based on a federal ban on the sale of guns to users of illegal drugs. Though marijuana has been legalized in some places on a state-by-state basis, it remains illegal under federal law. The court maintained that drug use “raises the risk of irrational or unpredictable behavior with which gun use should not be associated.”
Wilson claimed that she doesn’t actually use marijuana, she simply obtained a card to show her support for its legalization. The appeals court agreed with guidelines from the federal Bureau of Alcohol, Tobacco, Firearms and Explosives that firearms sellers should assume that medical marijuana card holders use the drug.
