There are many reasons you would want to cleanse your body of all THC and related byproducts. For most people, it’s either to pass a drug test or to reap the benefits of a tolerance break.
However, beating a drug test is a drastically different objective than ridding your system of cannabis. Typically, the need to beat a drug test arises on such short notice that it’s impossible to clear the body of THC and its metabolites – so the objective becomes to simply hide, or mask, any evidence of its existence. What does this mean? Abstinence is the only surefire way to rid your body of THC.
