your real lucky dude, i'm sitting having a bowl with a friend who works for local drug project has lots of experience with testing , he says that if you test positive he will he will start doing gay porn.
basically you cant test pos from a few joints a couple months ago . unlike most drugs cannabis builds you in fat reserves so it stays in system for up 2 30 days and thats only if you are regular user ,

thats not my opionion this is a proffesionals.
goodluck you will be ok

by the way i think you would pass as well
