It's not going to be positive because I substituted- 1/2 Quick Solution and 1/2 real urine (not my own). The real urine was a somewhat diluted sample though cause my donor had to drink water in order to pee on demand for me. So I'm worried my sample was discovered to be fake. Haven't smoked in a week- since I found out I had to take the U/A but I'm a regular smoker, so most likely not within the range to pass on my own.
