John non pot head hadn't been smoking it, yet he got fired cause his friend had, would one suggest leaving the room when someone else has an alcoholic beverage, or that John non head had ridden on the car's luggage rack, I'm just making a point that as in many cases I too have witnessed in courts, the guilty go unpunished and the non guilty get punished. Thar's our "justice" system unfortunately, and the scales of justice will never be balanced, so the choice or rather recommendation to "Don't smoke it" doesn't mean a hoot, however had they both of been doing Coke, and since Cocaine stays in your system for 12-72 hours, not up to 30 days, he'd been just fine, now is that a fair system?
Yeah but none of those items are my issue, and my point is simple. I don't care what you do as long as you don't steal another person's freedoms. The penalties should be severe when you get high on whatever and hurt another person. And if there is no reliable way to prove it's out of a person's system, then perhaps they should find another drug of choice.
