People in states that allow either recreational or medical marijuana use are going to face big problems from the new form 4473, which apparently makes it a crime to purchase a gun if you use marijuana. I asked in my email to the legislative committee: "If marijuana users aren't allowed to purchase guns, doesn't that mean that if a marijuana user already owns one, he/she would have to dispose of it, or law enforcement could take it away?" I provided a link to a Portland Press story about the new form 4473. In my email, I mentioned the U.S. Supreme Court decision Alden v. Maine, and quoted from it: "the original understanding of the Constitution's structure and the terms of the tenth amendment confirm that states retained much of their sovereignty despite their agreeing that the national government would be supreme when exercising its enumerated powers."
So, law-abiding citizens who turn in their guns, or don't purchase them because of this new question on the form 4473, will be helpless against the real criminals. Anyone can get a gun, whether it be through a friend, or through a failed background check as shown below. Pete had been labeled a felon, due to a conviction in 1981, but was still approved.
