Okay, so I was at a party about 5 days ago and there was a LOT of cannabis being smoked by some people there, and I was outside for some time, and the smell and smoke was thick and strong, also I was inside for some time and i must have been around the smoke for around 3-4 hours in the living room, and I just had a drugs test. I am absoloutely distraught because I think it will turn out positive... should I be ?
