On a tangent, I wonder how many gun buyers in states where recreational pot is legal, lie on the 4473?
I'll concede that a bunch of them who mark "no" are probably doing so because they think pot being legal in their state makes it okay. That's language that could be updated on the 4473, e.g., with some statement specifically that pot is illegal on the federal level. Though I guess they would need a separate statement for Oregon, where anything goes drug-wise these days.
