The 9th U.S. Circuit Court of Appeals has decided that if you have a medical marijuana card, you can't buy a gun because it “raises the risk of irrational or unpredictable behavior with which gun use should not be associated.”
Seems somewhat interesting, as you see people stumbling over at the bar from alcohol use.
The court ruled in August of 2016 and voted 3-0 to ban the medical users from obtaining the weapons. They claim that it does not violate the 2nd amendment.
The court agreed with guidelines from the federal Bureau of Alcohol, Tobacco, Firearms and Explosives, saying that firearms sellers should assume that medical marijuana card holders use the drug, even if they don't.
“We live in a world where having a medical marijuana card is enough to say you don’t get a gun, but if you’re on the no fly list your constitutional right is still protected,” says Chaz Rainey, attorney representing one woman's appeal against the verdict.
Marijuana law expert at the San Diego’s Thomas Jefferson School of Law, Alex Kreit, suggests that we will more on the issue, arguing “that they shouldn’t be lumped with other drug users in terms of concerns about violence.”
Marijuana is now fully legal in seven states across the US.
