Do you think it is fair to still allow certain states to test for THC and then be allowed to exclude a person from being hired based on a positive test?
Regardless of a state's own laws regarding the consumption of marijuana, more and more state's are making marijuana legal. So since there is nothing illegal about visiting a state say Colorado and consuming what would be considered a controlled substance elsewhere, a business should not be able to legally exclude you from employment, nor should they even be allowed to test for the presence of THC.
*EDIT*
Just to clarify... I was referring to the initial hiring process.
I was not referring to showing up to work stoned and then being given a random, or not-so-random drug test and being fired. Showing up to work inebriated drugs, alcohol, or prescriptions, is grounds for dismissal or at the very least being sent home for the day.
I am not a druggy, and haven't been irresponsibly drunk or otherwise for a long time. I was more or less simply trying to spark a discussion regarding certain laws currently in place, and how those laws may have a few holes at the moment while states try and figure out where they stand on the issue.
