It's not about getting stoned and shooting guns. It's about Form 4473 explicitly banning anyone who uses weed from buying or possessing a firearm, under penalty of Federal felonies. E.g. if a buddy comes to visit from out of state, hasnt used weed in a month, and you take him to the range to shoot your guns? Congrats, you just committed a felony by placing your guns in the Possession of a Prohibited Person. He gets a felony, you get a felony, and the ATF seizes your guns. Sell a rifle to your buddy? Congrats, you just Transferred a firearm to a Prohibited Person. Across state lines no less. Felonies for everyone! The judge is addressing the longstanding issue where you can use use other drugs and still own and shoot guns so long as you're sober at the range. If you go shooting and then go home to drink alcohol, take pain meds, etc you're A-OK to exercise the 2nd Amendment. But weed instead of a fifth of vodka? No 2nd Amendment for you ever. It's obviously an absurd double standard.
