havent been tested yet.... just used an Aimscreen test strip, dipped it into the QF4.0 bottle and the test came up positive. I didnt heat the urine up but it doesnt say that it matters on the instuction, i also retested myself after only toking like twice in the past 2weeks and i came back with a faint negative line.

Any reason why QF made the strip positive? Does QF typically pass strip tests?
