Drug overdoses are a leading cause of accidental death in the United States. Among all overdose deaths, opioids were the culprit 70.6% of the time in 2019, according to the Centers for Disease Control.
Nearly 30 years after the first wave of the opioid epidemic began, roughly 645,000 Americans have died from overdoses where prescription or illicit opioids were involved, according to the CDC. Current estimates indicate that between 6.7 and 7.6 million Americans suffer from opioid use disorder.
Beginning in 2013, the introduction of synthetic opioids like fentanyl and xylazine into the drug supply sparked a surge in opioid overdose deaths. According to the Department of Health & Human Services Overdose Prevention Strategy, drug overdose deaths due to synthetic opioids besides methadone have increased an astounding 103-fold since 1999 and are the primary driver of overdose deaths.
During an overdose, opioids bind to receptors in the brain that control respiratory function, leading to impaired breathing and amounting to brain damage and death due to lack of oxygen. In recent years, drugs to treat substance use disorder and prevent overdose deaths have surged in usage.
Naloxone, available as a nasal spray or injectable medication, can reverse opioid overdoses after they happen. The drug, often known by the brand name Narcan, was made available over the counter in 2023 in an effort by the Food and Drug Administration to increase accessibility. Nearly 1.7 million prescriptions of naloxone were dispensed in 2022, up from 904,000 in 2019.
Buprenorphine, however, must be prescribed by a health care provider as part of a long-term substance misuse treatment plan, often for those addicted to heroin, oxycodone, fentanyl, or other opiates. Buprenorphine works by reducing withdrawal symptoms and curbing drug cravings. As a long-acting opioid, it takes more time to act on the body over a more extended period. Though it's classified as a Schedule III drug due to its addictive properties, at the correct dosage it helps give people suffering from addiction a level of stability by reducing the harms of illicit opioid misuse.
About 16 million buprenorphine prescriptions were dispensed in 2022, slightly higher than in 2019. However, as the epidemic retains its grip on the nation, medical professionals are prescribing opioids for pain relief with less frequency. The rate of opioid prescriptions for pain fell steadily between 2019 and 2022, from 46.8 per 100 people in 2019 to 39.5 per 100 people in 2022. The prescription rate for opioid treatment drug buprenorphine, meanwhile, slightly increased over the same period from 4.7 to 4.8 prescriptions per 100 people.
Part of this increased access is due to the $50 billion opioid settlement fund distributed to each state for opioid harm reduction and treatment services. Many states are in the process of determining how to deploy settlement funds; the level of access to lifesaving medications thus varies by state and their specific approach to combating the crisis.
To compare how states are utilizing these funds, Ophelia used CDC data to map the growing distribution of common medications that prevent opioid overdoses and treat substance use disorders.
