Yes you can!! My bf is on probation and he doesnt smoke it at all and he was around his brother who smoked and guess what? He pissed positive!! So yes it can be in your system even if you don't smoke it
Passive smoking is detectable and can derail your job prospects if you are tested.
No, you can't get it in your system because it is a drug that shows up in your blood stream and it can't get there if you don't smoke it. You can be around it all day from somebody else smoking it, but you will test clean if tested because you didn't physically inhale the marijuana cigarette
