i'd say it solely depended on the weight/fat weight of a person, their lifestyle and their metabolism...

just guessing here... but as an example under my theory.. a 300 lb person that's like 6 foot that doesn't get much excersize and has a slow metabolism would take by far, much longer then a 6 foot 120 pound person with a very fast metabolism and an active lifestyle.

cuz the only thing that really explains tollerance, is the fact that by-products of the bud stay in your system, thus your body is used to having it there, and it takes a lil more to get the same effect as if you're clean... and since thc is stored in fat, that's why those factors would greatly affect tollerance.
slipknotpsycho Reviewed by slipknotpsycho on . Does anyone here have a clue about how much your tolerance goes down each day? That you don't smoke? Cause for some reason I hear in a week your tolerance can be like halved but it takes 5 weeks for complete tolerance-free. So what's the real truth? Rating: 5
