Specifically I'm referring to the NICS background check for buying a gun, but if other laws have other standards I'm interested in them as well.
If I took one puff off a marijuana cigarette at a concert 10 years ago, am I user? What if that concert was yesterday instead?
If I smoked habitually 10 years ago, but haven't had a puff since, am I a user?
I know practically it would usually be impossible to prove someone took one puff a decade ago, but that doesn't change the legality of marking "No" on that question on the NICS check.
I ask because NY just legalized recreational marijuana, but the Feds still haven't, so many New Yorkers may be unwittingly lying when buying guns.
