I am not saying it will clean you out, I am just asking if it would help the process. Yes the BAC, even at its highest, will not go over .2% or you won't be standing at least not well. But this being said, the THC contents of your fat cells is nearly as low (fractions of a percent) seeing as it can only chemically bond to the end of fatty acid chains... or at least it should only be able to. So even if you are running .2% alcohol in your blood, and you are pumping ~5 liters per minute of blood through your system, that is a substantial amount of alcohol over a few hours. Like I say I am not saying this will completely clean your system, but theoretically it should help... no?
