The only way any one would fail a UA with QF is if the temp was out of range. Or possibly you had MJ residue on your hands and you contaminated the sample by handling it.
killerweed420 Reviewed by killerweed420 on . Has anybody failed using quickfix 4.2 I have a test in like 12 days. I just ordered qf4.2 and I have a test for a probation officer. I haven't failed one test in 10 months, but I just smoked and I only smoked 2 bowls of some great weed. I can probably just dilute (after 12 days) but I figured I'd smoke and just sub. Then, I found 1 story about someone failing with 4.0. Anybody that has used formula 4.2 and passed or heard of the testing facility discovering that it's synthetic??? Rating: 5
