Oklahoma state law dictates that any person who is “ineligible to possess a pistol due to any provision of law of this state or the United States Code”shall be deniedthe right to have a handgun license pursuant the Oklahoma Self-Defense Act.(21 O.S. § 1290.10(9))Title 18 USC § 922 (g) (3) federally prohibits anyone “who is an unlawful user of or addicted to any controlled substance” from firearms possession.”According to a 2011 Open Letter to All Federal Firearms Licensees (FFL)written by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), “any person who uses or is addicted to marijuana, regardless of whether his or her State has passed legislation authorizing marijuana use for medicinal purposes, is an unlawful user of or addicted to a controlled substance, and is prohibited by Federal law from possessing firearms or ammunition.” The letter tells FFL’s, “if you are aware that the potential transferee is in possession of a card authorizing the possession and use of marijuana under State law, then you have‘reasonable cause to believe’ that the person is an unlawful user of a controlled substance.”Unless and until the federal government changes marijuana from the Schedule 1 Prohibited Category, possession and use of medical marijuana will make a person ineligible to possess firearms. Purchasing or possessing a firearm as a marijuana user is still a felony. I know a few who say it shouldn't matter, but it's a law. And before anyone refutes the logic behind it, build some class three stuff without stamps and flaunt it on facebook. Let's see what you really think of stupid laws.
