Cocaine can be detected in the system anywhere from 12 hours to 4 days after use. The length of time cocaine stays in your system depends on the dosage amount ingested, the route of administration and frequency of use. When cocaine is metabolized, the liver turns it into benzoylecgonine, which is then excreted in urine.
BUT, if you chew gum a lot, especially if you have a lot of tension in the muscles of mastication anyways, you're going to have problems... The muscles that make the motion/act of chewing/clenching include the masseter, lateral/medial pterygoids, and the temporalis.
The origin point of the Temporalis Muscle is along the entire rim of the Temporal Fossa of the Skull and itâs insertion point is the coronoid process of the mandible. The Masseter Muscle is a thick muscle which is primarily responsible for our chewing action. It is one of the strongest muscles in the entire human body.
