i read a thing on this website ill try to find it and post it for you. but anyway it tells you in how many days time you will be clean after smoking certain amounts. like i know that if you only smoke one to 2 times a month you will be clean in 5 or so days. but there is a whole time table and stuff. i think its on www.hightimes.com but i know for sure there is a link to it on that site. so you may wanna check it out if you are wondering how long it will take to get clean
