Tons of people who smoke weed and had to say "yes" to the "are you not a drug user" and lied on a form to get guns were just found by the US Supreme Court 9-0 to not be violating the law:

Hunter Biden trial would never have happened now too because of this - many people at the time wanted him to fight it out and be the poster child for this rather than the Pakistani guy in this version of the case.

So actually, you can indeed just say "yes" and than "vote your conscious" anyway, even openly - at least in the case of the few states that don't have "willing to nullify" as an acceptable reason to strike a juror during jury selection.

Note in this case guy was in an illegal state and also had cocaine.
