Hi, I haven't smoked any weed since June. Yesterday I had about 9 puffs with a friend. Today I went to a place and was offered a PT job. I need the job & told them I would be able to return my papers in 2 weeks to be on the safe side. My question is after smoking yesterday when can I be absolutely positive the THC won't show up?? I thought for a person who hasn't smoked for over 3 mos. it might be 3 days. Please tell me if you know for sure. I'd like to call the co. as soon as I can pass the drug test. Thanks all. I am 5'6" tall & weigh 215 lbs. I also am phisically active. I either walk 1 mile a day or play tennis for 1-2 hrs. @ a time in a hot climate. I sweat alot all the time.
