But, but I thought the effects of marijuana lasted for days, not just two hours.
Gee, if you are right then the pilot of the plane that crashed could have smoked pot a week or more before the crash and still tested positive for pot and the pot would have had no effect on him.
You make a strong argument for my side, RP. Thanks for pitching in and helping.
Wrong yet again. The effects lasts for hours. The inactive carboxy THC metabolite may stay in the bloodstream for five to eight days or longer.

If the test is a simple "postive/not positive", sure. But the test did an actual count which led investigators to believe he might have smoked recently.

You're welcome. That comment almost made it into my profile page.
