Employers do have the right to discriminate who they hire and who works for them. They can't discriminate for "certian" reasons, but MMJ hardly qualifies as a civil liberty. Choosing to use it is not the same as your race, religion, sex preference, gender, ect...
That is why employers can discriminate. I use MMJ, don't get me wrong. But it is a plant. Current federal laws just make a bigger issue than it should be. But employers can and do discriminate and should have the right to.:thumbsup:

IT'S THEIR GOD DAMN BUSINESS!
