I had to take a hair test for a promotion at work yesterday. I have only smoked around 4 times in my entire life; however, the last time I smoked was around 137 days ago where I took a single hit of a girls bowl. I know I shouldn't worry because the test was only for a 90 day period, but the nurse who took my hair didn't measure the hair and it's possible she could have taken a little more than the designated 1.5 inches. My hair isn't long, but I'm not sure the lady was very competent. I'm worried that this could potentially put me in danger of failing because the test company in Psychemedics. Should I be worrying? Nearly everyone has told me I have nothing to fear. Thanks!
