Another question is, if I am in an enclosed area e.g ( A Van )lets say 30 mins to an hour, with all windows closed. They are smoking constantly. They light up 2 blunts, and smoked about 10 bowls. Will that have ANY affect on me failing another drug test.
Yes, if you catch a buzz and are around it enough then your inhaling enough to show up if a random thing you could be alright.
