Can you use 100 percent cranberry juice to flush your system of marijuana and if so how long does it take?

Cranberry juice will not clean marijuana, or any other drug, out of your system.

Water will not work either. THC is fat-soluble. It is stored in your body's fat cells. Since fatty substances are not water-soluble (remember what happens when you mix oil and water) drinking water does nothing to help remove THC from your body.

Neither will niacin, pickle juice, vinegar, bleach or any other "home remedy" you may have heard of.

For daily marijuana smokers, it takes 2 to 6 weeks, or a month on average, for your urine to be clean. For occasional smokers, the timeframe is more like 2 weeks to one month.
