Very puzzling. No prescribed Xanax will not cause a false positive.

Next, were you using just a THC test or a multi panel test? Were you using first voids or when? Were you drinking a lot of fluids when you passed or really dehydrated when you failed? Any aerobic exercise in there?

Thousands of people have passed using Quick Fix, maybe hundreds of thousands. If you are freaked out about it there is no reason. Employment test are not observed unless you give cause.

You will have 35 days clean by the test. I you really want to dilute instead of subbing, which is what I normally recommend, you would have a great chance of passing based on the clean time if you are still failing tests. You need to read the sticky on dilution again though to read about the TUms/Rolaids and red meat (and fish BTW).
FakeBoobsRule Reviewed by FakeBoobsRule on . Passed home test 3 days and 4th day failed? I passed my home drug tests for three days after not smoking for 23 days -- the forth day, after taking a prescribed Xanax the night before, I then failed twice today. Does this make sense? I thought once negative, always negative. Does Xanax cause a false positive or is it common for my test to turn around and go back to negative? I haven't changed anything else so I have to attribute the failure to the Xanax. Am I making the wrong assumption?:(:(:( Rating: 5
