Unusual Drugs of Abuse in Chronic Pain Patients
Chronic pain occurs in one third of the American population. Management of chronic pain is a growing area in health care; however, there is a dilemma for health care providers to treat the chronic pain of individuals who have known current or suspected drug abuse or addiction. Even if the individual is not addicted to opiates or prescription pain medications, it is possible to become addicted to a new substance. The National Institutes of Health considers drug addiction a neurophysiologic disease, and as of 2014, 24.6 million people in the United States abuse drugs. As more patients are seeking treatment for chronic pain, health care providers are seeing an increase in patients who have a history of drug abuse or addiction, and it is imperative that health care providers are aware of how best to care for these patients. This review discusses chronic pain and the drugs that are typically used to treat chronic pain, as well as drugs that have been reported to be abused in chronic pain patients. There are limited or no data available on the more recent designer drugs, such as bath salts, K2 (spice), and even common drugs of abuse, such as methylenedioxymethamphetamine (MDMA). More research should be conducted on what drugs are abused in chronic pain patients, especially nonopioid drugs such as stimulants. This information would help educate health care providers and create better pain treatment regimens for patients who abuse drugs.
