WA state does not specify, to my knowledge. We are not allowed to carry any weapon, CC or OC, into a facility that SERVES alcohol AND is off limits to persons under 21. There is no law that says you cannot drink alcohol while armed.
If you're drunk, you can get it taken away!
RCW 9.41.098 - confiscation of weapons
(e) In the possession of a person who is in any place in which a concealed pistol license is required, and who is under the influence of any drug or under the influence of intoxicating liquor, as defined in chapter 46.61 RCW;
46.61 defines a driving limit as 0.08... but otherwise leaves it up to discretion by defining as: "under the influence"
does anybody know if WA law extends to places which do not require a CPL?
