It took me 21 days to piss clean. I'm 6'5, 220lbs and was a regular smoker. My neighbor took 47 days to piss clean. He's a pretty big (fat) guy and a chronic smoker. His wife took 12 days (small build, skinny). For you? Who knows. Keep testing yourself periodical, using the first urination of the day. Some of my other threads I talk about the FirstCheck drug test that allows you to send your sample in for a free lab test that gives you a quantitative measure of how much thc is in your body, I highly recommend this type of test, especially for someone like you who wants to go all natural, as you can see exactly how far away from pissing clean you are. You can pick them up at you local pharmacy. Search for some of the recent threads I've started if you want to. All the information is in there..
