I would figure in legal pot states, it should probably be handled like alcohol. Don’t come to work high or drunk, and don’t get high or drunk at work or on lunch; i.e. just like now if you have a couple drinks at home before you sleep, you’ll be sober when you wake up, you can’t smoke so much as to leave you high in the morning.
(I’m an ex-tobacco smoker, and I don’t smoke pot myself. I don’t really approve of legal pot smoking, but, if it was voted to be legal by the people of the state, I don’t know that it’s my place to say they can’t. )
But tobacco is so sacred Native American.
Do I get an exemption?
This is my problem with legalizing recreational drugs. What do the various law enforcement agencies now require from recruits and long-time members? What about professional organizations, just as law and accounting certification groups? Will cops now be allowed to "light up" off duty and still keep their jobs? Will lawyers and accountants now be exempt from this long-standing ethical standard?
