The cheek swab detects THC which has come in contact with epithelial cells and is later sequestered in the cells. The swab will detect THC up to 36-48 hours after use. Brushing, drinking, and eating may speed up the process of elimination because the cells slough off.
Not smoking marijuana would be the best way of avoiding a positive test.
