people who should not smoke at work:

1) pharmacists (they will mix up the quinine with the quinidine and stop some poor fucker's heart!)
2) airline pilots (remember john denver's "rocky mountain high?" what was the pilot smoking? he was actually crashing on a jet plane not leaving on one
3) active-duty military personnel (if they smoke weed they might just see through the bullshit propaganda their country is feeding them and might not want to fight a war)
4) radiation therapists (oopse, sorry mr. cancer man, we accidentally fried the wrong cells around your cancer and now you have to come back and see us even more. We'll bill medicare)
5) george bush-- (he is stupid enough without weed and prefers cocaine and oxycontin, I'm guessing)

people who probably smoke at work:

1)call center representatives (they are usually idiots anyways--and call centers don't drug test, generally. who works in a call center anyways????)
2) automobile mechanics.
3) Donald Trump -- tell me you wouldn't smok fat blunts with all his money??
4) nurses who deliver babies-- i would have to be high to look at what they look at all day.
5) the idiot at the smoke shop who tried to hit on my wife and as a consequence got a stern warning to never do it again!
