I tested positive for THC today and I don't smoke nor am I ever around anyone that smokes weed. I demanded another test on the spot. I even offered to let them watch me do it. I was denied. So as of now my urine is off at lapcorp being tested. Though I'm wondering if it's even mine since they just have me lay it on a table and mark nothing. I've been extremely upset all day. How in the heck did I test positive for THC??! Has anyone else ever had or heard of this problem?? Please Help.! I feel like I'm marked or flagged now all for something I didn't even do..
