Once oxycodone enters the body, it works by stimulating certain opioid receptors that are located throughout the central nervous system, in the brain and along the spinal cord. When the oxycodone binds to the opioid receptors, a variety of physiologic responses can occur, ranging from pain relief to slowed breathing to euphoria.
When abused, OxyContin, like other opiates and opioids, can be dangerously addictive.
Rather than ingesting the pill as indicated, people who abuse OxyContin use other methods of administering the drug. To avoid the controlled-release mechanism, they either chew, snort or inject the medication to get an instant and intense "high." Frequent and repeated use of the drug can cause the user to develop a tolerance to its effects, so larger doses are required to elicit the desired sensation and the abuser gets increasingly addicted to the drug.
