Hi, I'm posting because I have a PO meeting coming up Monday December 14th. On December 6th I got little drunk and puffed about 6-7 hits off a joint. So it'll be 8 days clean. Also before that weekend I had last smoked 11 months prior. I'm 6'1" and about 175lbs. I've searched far and wide all over the internet for good advice and get conflicting results. Tons of morons say for any amount it's 30-90 days. What I've read from seemingly more intelligent people is that it will be in the system, for one joint, 1-7 days and others say 2 weeks. I also know that the tests are at 50ng. So my questions are how long is one joint in the system? How high of a nanogram rating is one joint of mid grade weed? And do you think I'll pass? I cannot at this moment afford to buy an at home testing kit either. Any great advice is appreciated.
