I have a drug test coming up in the next two weeks. I am not sure what type it is but I am preparing for the worst (hair test). I have a couple of questions. 1. Can second hand smoke cause a hair test to come up positive? 2. Anybody have any experience with a company called Verifications Inc. That is the place that the company I am applying for uses. What type of tests do they use? Thanks for any input. By the way I havent smoked for a little over a year so my only concern is sekond hand smoke.
