      Remember - the drug latches onto your fatty tissues. Therefore, a higher body fat level will have the opposite effect, taking a long time to detox and rid the metabolites from your body. Click Here to Detox Your System in 5 Days > There are a few tactics - natural and supplement-based - that can help flush the drugs from your system if you have an upcoming test. For the most part, the supplement products will give you a better shot at passing. If you let marijuana take its natural course to leave the body, it'll take a few weeks or even months. Since cannabis is stored mostly in fatty cells and tissues, the amount of time it takes to detox will depend on the person, with body mass and metabolism playing the biggest roles.
