I have a lot of employees and would be employees that take drug screens for
the companies I represent and have spent a lot of time dealing with the
results and I'd be tickled to death if you could find me any proof that just
being in a room with a pot smoker is enough to make you test positive much
less being in one where someone has smoked in the past. If you test positive
for pot you got enough in you to get high.

When I was in high school the student bathrooms seemed to vent into the
gym teachers office. They had to abandon their offices during lunch
periods because they ended up too high to teach their next classes.
