OK PDX, if the fact that they were all using drugs is no big deal, tell me this.

You have a choice of riding on a bus/plane/train being piloted by someone who uses drugs, and someone who doesn't. Go ahead and tell me you don't care which one you or your family rides on.

If you want to say people have the right to get high, etc thats fine. But they have no business doing so in the workplace or where they endanger others. Sadly, unless you sit in your basement and get plowed all by yourself and never leave, you're probably putting other's safety at risk.
