Hello everyone, So my employer require new hire to do Urine and Hair Drug test. My urine test result was Negative, however the Hair Follicle test returns Positive. I was shockingly surprised as I have never smoked anything my entire life. However, I do live with 2 roommates who do smoke quite regularly. Though, I was never in the same room or see them smoke directly, I can occasionally smell when they're smoking it. After doing a lot of reading and visiting forums, I'm quite positive that it is impossible for me to inhale enough smoke to have a positive result. I request a retest but they said it can't be done since they used all the hair sample. I'm just wondering if anybody here experienced the same situation or have any suggestion. I will do another test to verify the result myself. In the case that I did inhale too much for the THC to get into my system, what is the best way that I can flush everything out. Thanks in advance!
