this has kinda been going on for a while though.

I'm not sure the situation. first of all it's been on form 4473 to buy guns forever (last 10 years at least) about if you are under mental healthcare

it is not checked federally and never had been

some states check TDO s (Virginia) and deny through that but that part of form 4473 had been under penalty of perjury

same with drug use

so before you speak of what you don't know talk to someone who knows.
