First, I think Pot should be legal, At the very least put it on the same level as booze.
But one thing I have to ask is, since just about any job in Manufacturing, Industry or Transportation requires a drug test, what will be the case. Unlike booze, a drug test, especially the ones where they use hair samples, can show up months after usage.
At my business, we have random drug test, mainly for insurance purposes. How will Industry deal with this if Pot is indeed made legal?
