Opioids are a class of drugs used to reduce pain, and include legally prescribed oxycodone, fentanyl, buprenorphine, methadone, oxymorphone, hydrocodone, codeine, and morphine as well as illegal drugs such as heroin. Beyond pain relief, opioids lead to feelings of euphoria and well-being, which can contribute to a feeling of “high” and addiction. This is one reason why opioids are often abused.

Causes and Risk Factors

Continuous use of opioids almost always leads to physical dependence. When a person becomes opioid dependent, they’ll have a high tolerance and need increasingly larger amounts of the drug to achieve the desired effects. This can be very dangerous, and increases the risk of accidental overdose. A person also becomes ill when they stop taking the drug or reduce their normal dose. If opiate consumption stops, withdrawal symptoms such as intense shaking, sweating, vomiting or headaches occur. Many people become dependent on these drugs in order to avoid the pain associated with withdrawal symptoms.
