Wilson v. Lynch: Do Medical Marijuana Users Lose Their Second Amendment Rights?

Does the use of medical marijuana in accordance with the laws of a given state strip the user of their Second Amendment rights? The answer, per a recent ruling from the Ninth Circuit Court of Appeals, is yes. Furthermore, they held that the mere possession of a registry card constitutes “’reasonable cause to believe’ that the person is an unlawful user of a controlled substance” and therefore prohibited from purchasing a firearm from a federally licensed dealer.
