Haha, no. Cannabinoids, such as THC, are fat soluble. which means they're not water soluble, because oil and water don't mix if you recall.<br />
what you need to do is eat lean and exercise.
daily smoking may take as long as 40 days...light toking and maybe a few hits a week may be gone as fast as 16 days...are you studying for a test ?
there's an easer way, just don't smoke it.
Don't drink TOO much water the day of- honestly if you pee clear it's just as bad as failing.<br />
That being said most UA's are looking for a minimal level not actually all of the THC in your system.<br />
Additionally THC is absorbed through the fat, idk how much time you have but if you are "fit" putting on a few pounds doesnt hurt... if you are not fit it's not really that useful.
it will, but only up until like 24hours before hand when it will wash out your urine...
peeing clear is bad
a cup or two of cranberry juice and regular exercise can help, too
