It doesn't matter to your employer or insurance if your high or not, but you can bet your ass that they will try their hardest to pass blame to you, to avoid liability or payment. Just saying that to me it's not worth it to jeprodize a 6 figure job. The onus will then be on you to prove your innocence, pretty hard to prove innocence if your passing doobies while training people. Just saying, not the best way to do things. I'm sure your a big boy and can make those judgment calls yourself. Not judging, I drive high all the time, but I know where to draw the line. I refrain when my responsibilities out weigh my personal beliefs, like at work or with kids in the truck, I would rather be safe than sorry.
Itsme.
