Full body detox is always good, once in awhile. It will actually clean out all environemental toxins from chemicals to anything toxic in your body. A full body detox will clean your entire colon also. Don't get the misconception that a full body detox will immediately clean out all THC metabolites as these will only be cleaned out with time, since they are actually stored in your fatty tissues. But a full body detox will clean out harmful bacteria that has stored up over the years.
