This is why I dont do it You can be on Nyquil and be considered intoxicated. Basicly if you on any substance that affects your judgement blah blah blah etc. etc., dont get caught with a firearm. Not a good idea to operate a motor vehicle either while under the "influence" either.
It's up to the OP's son to decide if he wants to take that chance or not. Hopefully takes my advice, if alcohol is around, the guns need to be put away ( at home, in a safe, whatever, but not on or near your person ).
