When in doubt I generally lean towards the employer being able to fire people for just about any reason they choose. If you don't like the rules then don't work there, generally.
Drug testing for marijuana is kind of dumb though because it stays in your system so long and isn't a highly addictive and dangerous drug like heroin or meth. So as has been mentioned you can have smoked a joint a week ago and test positive. It's also very possible that if you live in a state that has legal weed you can go to a party or other place where people are lighting up all around you and you end up with some in your system even though you didn't partake yourself intentionally.
I'm guessing though that virtually all of the folks in WA that think you should be able to mandate the hell out of vaccines and fire people for not taking them.
