I don't smoke much except a couple hits about an hour before bed to help me sleep, and only do it 3 - 4 times a week. I just got called for a job and have to go in and have a piss test within the next 48hrs. I bought the Herbal Clean SUPER QCaps Extra Strength 4 concentrated capsules. I called the company and read a few reviews on it and I can not find how fast it works. Has anyone tried or does anyone use this product, and how long before I can go in for the test?
