Individuals with mental health and substance use disorders (SUDs) are particularly susceptible to negative effects of the coronavirus disease 2019 (COVID-19) pandemic. The collision of the COVID-19 pandemic and the drug overdose epidemic has highlighted the urgent need for physicians, policymakers, and health care professionals to optimize care for individuals with SUDs because they may be particularly vulnerable to the effects of the virus due to compromised respiratory and immune function, and poor social support.1 In this commentary, we highlight the challenges of the drug overdose epidemic, and recommend strategies to mitigate the impact of the COVID-19 pandemic among patients with SUDs.
A crisis exacerbated by COVID-19
The current drug overdose epidemic has become an American public health nightmare. According to preliminary data released by the CDC on December 17, 2020, there were more than 81,000 drug overdose deaths in the United States in the 12 months ending May 2020.2,3 This is the highest number of overdose deaths ever recorded in a 12-month period. The CDC also noted that while overdose deaths were already increasing in the months preceding the COVID-19 pandemic, the latest numbers suggest an acceleration of overdose deaths during the pandemic.
What is causing this significant loss of life? Prescription opioids and illegal opioids such as heroin and illicitly manufactured fentanyl are the main agents associated with overdose deaths. These opioids were responsible for 61% (28,647) of drug overdose deaths in the United States in 2014.4 In 2015, the opioid overdose death rate increased by 15.6%.5
The increase in the number of opioid overdose deaths in part coincides with a sharp increase in the availability and use of heroin. Heroin overdose deaths have more than tripled since 2010, but heroin is not the only opiate involved. Fentanyl, a synthetic, short-acting opioid that is approved for managing pain in patients with advanced cancers, is 50 times more potent than heroin. The abuse of prescribed fentanyl has been accelerating over the past decade, as is the use of illicitly produced fentanyl. Evidence from US Drug Enforcement Administration (DEA) seizure records shows heroin is being adulterated with illicit fentanyl to enhance the potency of the heroin.6,7 Mixing illicit fentanyl with heroin may be contributing to the recent increase in heroin overdose fatalities. According to the CDC, overdose deaths related to synthetic opioids increased 38.4% from the 12-month period leading up to June 2019 compared with the 12-month period leading up to May 2020.2,3 Postmortem studies of individuals who died from a heroin overdose have frequently found the presence of fentanyl along with heroin.8 Overdose deaths involving heroin may be occurring because individuals may be unknowingly using heroin adulterated with fentanyl.9 In addition, carfentanil, a powerful new synthetic fentanyl, has been recently identified in heroin mixtures. Carfentanil is 10,000 times stronger than morphine. Even in miniscule amounts, carfentanil can suppress breathing to the degree that multiple doses of naloxone are needed to restore respirations.
Initial studies indicate that the COVID-19 pandemic has been exacerbating this situation. Wainwright et al10 conducted an analysis of urine drug test results of patients with SUDs from 4 months before and 4 months after COVID-19 was declared a national emergency on March 13, 2020. Compared with before COVID-19, the proportion of specimens testing positive since COVID-19 increased from 3.80% to 7.32% for fentanyl and from 1.29% to 2.09% for heroin.10
A similar drug testing study found that during the pandemic, the proportion of positive results (positivity) increased by 35% for non-prescribed fentanyl and 44% for heroin.11 Positivity for non-prescribed fentanyl increased significantly among patients who tested positive for other drugs, including by 89% for amphetamines; 48% for benzodiazepines; 34% for cocaine; and 39% for opiates (P < .1 for all).11
In a review of electronic medical records, Ochalek et al12 found that the number of nonfatal opioid overdoses in an emergency department in Virginia increased from 102 in March-June 2019 to 227 in March-June 2020. In an issue brief published on October 31, 2020, the American Medical Association reported increase in opioid and other drug-related overdoses in more than 40 states during the COVID-19 pandemic.13
