Is it at all possible that the day before , this unfortunate chap was in a confined area like a lounge room and watched TV with his flatmate who was all gunja'd up , doobied out , etc etc ?
could exposure to exhaled weed smoke be detected in a wee sample or show up in blood tests ?
of course the amounts would have to be trace quantities , but would they be enough to declare a person as having "tested positive" ??
I enjoy raggae music just for something different sometimes and notice that the cigarette or weed stink appears on my clothes after a few hours in a club , question now is will i fail a test and if so , for how long after ?
anyone here have similar thoughts or concerns ?
