What are opioids?

​

Opioids include three categories of pain-relieving drugs: (1) natural opioids (also called opiates) which are derived from the opium poppy, such as morphine and codeine; (2) semi-synthetic opioids, such as the prescription drugs hydrocodone and oxycodone and the illicit drug heroin; (3) synthetic opioids, such as methadone, tramadol, and fentanyl. Fentanyl is 50 to 100 times more potent than morphine. Fentanyl analogues, such as carfentanil, can be 10,000 times more potent than morphine. Overdose deaths from fentanyl have greatly increased since 2013 with the introduction of illicitly-manufactured fentanyl entering the drug supply [CDC 2016b; CDC 2018b]. The National Institute on Drug Abuse [NIDA 2018] has more information about types of opioids.

All opioids are chemically related and interact with opioid receptors on nerve cells in the body and brain. Opioid pain relievers are generally safe when taken for a short time and as prescribed by a doctor, but because they produce euphoria in addition to pain relief, they can be misused (taken in a different way or in a larger quantity than prescribed, or taken without a doctor’s prescription). Regular use—even as prescribed by a doctor—can lead to dependence and, when misused, opioid pain relievers can lead to addiction, overdose incidents, and deaths.

What is the opioid epidemic?

​

From 1999–2018, almost 450,000 people died from an overdose involving any opioid, including prescription and illicit opioids.

This rise in opioid overdose deaths can be outlined in three distinct waves.

​

1. The first wave began with increased prescribing of opioids in the 1990s, with overdose deaths involving prescription opioids (natural and semi-synthetic opioids and methadone) increasing since at least 1999.

​

    2. The second wave began in 2010, with rapid increases in overdose deaths                                   involving heroin.

​​

    3. The third wave began in 2013, with significant increases in overdose deaths involving             synthetic opioids, particularly those involving illicitly manufactured fentanyl. The                       market for illicitly manufactured fentanyl continues to change, and it can be found in             combination with heroin, counterfeit pills, and cocaine.

Can an opioid overdose be reversed?

​

An opioid overdose can be reversed with the drug naloxone when given right away. Improvements have been seen in some regions of the country in the form of decreasing availability of prescription opioid pain relievers and decreasing misuse among the Nation’s teens. However, since 2007, overdose deaths related to heroin have been increasing. Fortunately, effective medications exist to treat opioid use disorders including methadone, buprenorphine, and naltrexone.

A NIDA study found that once treatment is initiated, both a buprenorphine/naloxone combination and an extended release naltrexone formulation are similarly effective in treating opioid addiction. However, naltrexone requires full detoxification, so initiating treatment among active users was more difficult. These medications help many people recover from opioid addiction.
