Alcohol, yes, but with marijuana, since the substance they test for stays in your system for a long time, no. Though the argument has always been that it's illegal and so more serious. And technically it's still illegal at the federal level, so o guess technically that's true, but the federal government doesn't often enforce it and in several states it's legalized. If it ever gets legalized at the federal level and they still do hair tests instead of blood tests, though, I don't see how they can justify that.

But in reality, pretty much the only people who get punished for marijuana use are either minorities or someone being targeted for something else they did and weed is just an easy excuse to fire them, put them in for-profit prisons, murder them legally, etc.

Umm, I don't know, probably. I'm just curious about jobs like that in another country
