Good luck. It's still a federal crime to posses/sell marijuana, state laws be damned. I doubt they'd get any leeway on any other state's rights issues involving guns.
There's a difference between a drug addict and a kid who smoked a joint in highschool and decided to be honest about it. All this is is more liberal trash to clog up the public works of this country.
I failed a drug test in the army. They still let me go to Iraq, but I guess I don't have the right to defend my wife and home for the rest of my life now?
Good luck retrieving my guns from me. Come get them yourself, Schumer.
