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.
This is a remarkably common problem, especially among the young. The muscles that allow you to chew (muscles of mastication) can be overworked and strained, the same as any other muscle in your body. If the muscles are well-toned, not weak, and not overworked/strained, this will not be a problem.
The Pterygoid muscles is made up of two muscles the Lateral Pterygoid and the Medial Pterygoid which are located on the inside of the Ramus of the Mandible and work in tandem with the Masseter muscle to assist in the chewing action, jaw rotation, side to side movement of the mouth and the projection of the lower jaw.
