One major problem with drug testing is they don't test for active drugs. They test for metabolites and other agents that show PAST use. Are you saying someone can't smoke weed today, and be coherent and competent a day, or a week, or a month later? THC metabolites can be present weeks after use, and are a p!ss-poor indicator of whether someone is using on the job.

Here's something I found amusing. After a train operator in NYC piled his train into the station and killed a bunch of people, they implemented a drug-testing program for train operators. You know, because this particular guy was DRUNK at the controls. Drunk at the controls? Let's implement drug-testing. F'n brilliance like that comes from people who need to be drug tested themselves.

Except they'd pass............and apparently being so f'ing stupid you should be prevented from breeding is OK.
