I have a question and I could really figure out where to post this.. soo About a year ago I went to get a drug test, now I smoke alot but when they did the drug screening (urine), my test all came back negative. I was wonder why would that be? I literally smoked as I was head to get the test done. So I'm confused why nothing showed? Someone once told me it's fat soluble and that could possibly be the reason why but I'm still not 100% sure. Anyone?
