If Your Around Marijuana Smoke Will It Show Up In A Test?

Most of the time, no. You'd have to be in a small closed room with huge amounts of smoke to get enough to show up on a test. The second hand smoke excuse for failing a drug test is a lame one. They usually don't test for that small amount. www.erowid.com

Yes, it happened to me, however I was in a car while it was being baked and they smoked like an 8th worth of weed....
The way I think you can tell is if you feel high afterwards because that is a clear indication that you have mind altering substances in your body...

Yes, it will only show a small amount on the test though.

No it won't. You wouldn't get enough THC in your system just from contact  to show up on a drug test.
