Hi everyone. I'm about to start a new job and have a UA at QuestLabs coming up, needless to say I'm a nervous wreck. I was a heavy user for more than 4yrs (at least once a day, and definitely more on the weekends). At first, I quit for approx 2 weeks in anticipation of a drug test until I my supervisor told me that I wouldn't have to take one. Stupid me...I took that like being given the green light to smoke, and went and had about 4 j's during that week, but haven't smoked in two days. Now, 1.5 weeks prior to starting and after receiving the job offer letter, the same supervisor is now telling me that I have to take a drug test after completing my training assessments (which should take about 1 week). That gives me a total of 2.5 weeks at best to detox. I'm 5'7 and a well built 170lbs...I exercise frequently, but am pretty sure I will fail a UA if I were to take one right now. Either way, I'm going to run out and buy some home drug tests to see where I stand. I've been doing a lot of reading on these boards and out of all the options substitution sounds best and seems like the only definite way to pass. I understand how QF works, but am considering using real urine from a friend that I trust. Does anyone know the heating techniques for real urine? I know you can throw QF in the microwave for 10 secs or throw a hand warmer on it, but would the same work for real urine? Also, how would I store the real urine before the test? Both QF and real urine are gonna be a hassle to get b/c they don't ship QF to my state and it's gonna be awkward to ask a friend for piss. So I'd like to hear some opinions on which one works better and can keep their temperature the easiest and the longest.
