Okay I have to take a drug test to get hired at best buy I could either take it today or tomorrow I bought qcarbo32 but after reading mixed reviews im not going to bank on taking that. I just realized one of my friends hasn't smoked in 3 weeks and has been working out a lot and using the sauna. He told me he would let me use his piss. I'm fairly certain his will pass with out a problem and i even have a 3 ounce plane shampoo holder thing to hold it in but the only thing that is still concerning me is keeping it between 90-100 degrees. Its August so I really don't think I'll be able to get any of those hand warmers. If I heat it up and then keep it in my groin area would it stay warm enough to still pass the heat part of the test? Any advice is appreciated. Also Is 3ounces enough urine?
