I just passed after a diluted 33 day quit and passed. Whew, after the H..l I put myself through worrying. I was still testing positive with 1st morning urine but had to take the test. I've smoked daily for about 7 years and not very large person. I wouldn't smoke anymore if I were you and if you want to go a la natural. OR....Quick Fix 4.0 seems to be a less worrisome way as per censes. Good luck. You should be fine.
