I can tell you this. I am 6'0" and 250 lbs. I keep myself well hydrated, and although I am not a tub of lard, I could stand to lose 25 lbs. I experimented on myself and stayed clean for 3 months. I then smoked a bowl of TOTAL CRAP (NC weed is TERRIBLE. Bible belt land you know) and tested myself the next morning. While it would have been an "official" negative, it was very very close to the limit. I was also able to fool it with another glass of water and a second test, but I was pushing the "too clear" limit.

I'm a big guy, and those at home tests are actually pretty sensitive. Not that they can't be defeated, but definitely do't smoke the night before your test.

I have a couple test kits here with me now. I might take some pictures and post a thread explaining everything, if you guys think it might help. Let me know if you think a quick illustrative post on testing procedures and what to expect would help.
