Alcohol is a legal drug.

Pot, depending on the jurisdiction, is not.

In those places where weed is legal, it still is not ok to show up at work under the influence - just as with alcohol. They need a test that can determine if someone is currently under the influence. At this time, they can only determine thru urine/hair/blood where it is in the system for a month.
