You guys debating about drug testing make me laugh. How is this supposed to work in the real world, where political correctness and cover-your-ar$e thinking dominates? Who exactly is going to perform the test and say "Yes, this drug is fine" ??? The same person who will get their ar$e sued when the user then goes ahead and has too much. Every single test would need to come back with "This is dangerous, you shouldn't take it" thus rendering the test useless as users will quickly realize the test is a waste of time. Come back to the real world and think about it.
