So I have to get a physical next week where they will also test my urine for drug use. I smoked, for the most part, every day for the past 2 and a half years. I'm 5'11'', weigh 150 pounds, and have a pretty fast metabolism. I also drink lots of water and black coffee on a daily basis. By the time I go in for my physical it will have been exactly 5 weeks since I stopped smoking. I want to take a detox drink on top of this just to be sure, but I'm not sure which one to take. Also is there anything else I could be doing to help my chances? Any advice or information would be greatly appreciated!
