I was the anti-drug program manager for an aviation business until a few months ago. Yeah, the secondhand stuff can show up in your urine, yes it can show up on a blood test, and you will never know if your roomies slipped something into the brownies or whatever. But don't take some idiot's opinion from the internet, call up the folks that do the testing (Norton Medical is a big one) and get your answer there.

Unless the guy is dying of cancer or in the end stages of glaucoma, the medicinal BS is pure BS. Even if the guy has those medical conditions, if the Feds show up on your doorstep, you will be arrested, too, aiding and abetting.

All and all, it is a nice way to watch a career go down the toilet and you didn't even get to partake in any of the "fun" of being a stoned loser.
