Q: I was at a party just now and 2 or 3 people were smoking weed. it was in a small apartment/area...maybe about 300-450 square feet.... If so how long does this stay in your system? I am barely starting to look for a new job and I wouldnt want to fail a drug test. Thanks in advance
A: Yes, secondhand smoke is secondhand smoke. You can even get what's called a "contact high" from it. This website ( http://www.passadrugtestingforall.com/long-does-marijuana-stay-your-system-a-4.html ) says it stays in your system for 3 - 90 days, but this depends on how much was ingested and how much was already there. This website ( http://wiki.answers.com/Q/How_long_does_marijuana_stay_in_your_system ) says if your system was clean to start and you only smoke one MJ cig, it'll be out of your system in 3-4 days. Depending on how much MJ smoke was in the room, it could be less than or more than 1 cig. Sounds like you should be okay if you don't have a drug test until after Labor Day - and you stay away from the druggy parties.
