About 3-5 days, but it depends on your metabolism and level of consumption.This is an acceptable answer if you're asking out of idle curiosity. If your employment is at stake, it's best to give yourself at least five days.If your freedom is at stake, give yourself at least a week or more. To my knowledge, there is no scientific evidence whatsoever that points to an effective way to eliminate the drug from your system any sooner than the rate at which your body metabolizes it, nor is there a scientifically proven method that will mask the drug while it remains in your system. I point this out because what worked for one person on one test may not work for someone else... It all boils down to your rate of metabolism and level of consumption.
