Drugs Most Frequently Involved in Drug Overdose Deaths: United States, 2017-2023
Summary
Fentanyl, heroin, and cocaine were frequently involved in US drug overdose deaths from 2017-2023. While heroin deaths declined, fentanyl involvement increased and stabilized, highlighting evolving overdose trends.
Area of Science:
- Public Health
- Epidemiology
- Toxicology
Background:
- Drug overdose deaths remain a critical public health issue in the United States.
- Understanding the specific substances involved is crucial for targeted prevention and intervention strategies.
Purpose of the Study:
- To identify and analyze the specific drugs most frequently implicated in drug overdose fatalities in the U.S. between 2017 and 2023.
- To examine trends and patterns of drug involvement over this seven-year period.
Main Methods:
- Utilized National Vital Statistics System mortality data (2017-2023) linked with death certificate text.
- Identified drug overdose deaths using ICD-10 codes (X40-X44, X60-X64, X85, Y10-Y14).
- Analyzed literal text fields on death certificates to determine specific drug involvement and contextual information.
Main Results:
- Fentanyl, heroin, oxycodone, cocaine, and methamphetamine were among the most frequently mentioned drugs.
- Fentanyl was consistently the leading drug and a common co-occurring substance.
- Heroin-related death rates declined, while fentanyl-related rates increased and then plateaued.
- In 2023, fentanyl, methamphetamine, and cocaine predominated in unintentional overdoses; diphenhydramine, oxycodone, and bupropion in suicide-related overdoses.
Conclusions:
- The landscape of drugs involved in U.S. overdose deaths has shifted, with a notable rise in fentanyl.
- Fentanyl's prevalence as a co-occurring drug underscores its central role in the overdose crisis.
- Continued surveillance and tailored public health responses are necessary to address the evolving patterns of fatal drug overdoses.

Prescription drugs require a prescription from a medical practitioner and can only be obtained from a pharmacy. They have many applications, including treating pain, anxiety, and hypertension.
The misuse and addiction to prescription drugs is a growing problem that can affect people of all age groups, specifically teenagers. This can happen when prescription medications are used in ways not intended by the prescriber, such as taking someone else's prescription or using medication for...

Drug Classes and Categories
3.3K
Drugs can be classified according to their chemical composition or their intended therapeutic application. For instance, anti-infective agents that possess the ability to eliminate pathogens or suppress their growth and reproduction can be grouped based on the organisms they target or their chemical structure. Furthermore, drugs can be divided into prescription, nonprescription, or controlled substances. Prescription medications, such as antibiotics, require oversight from a licensed healthcare...

Pharmaceutical Poisoning: Potential Scenarios
53
Pharmaceutical poisoning can occur through various channels, impacting an estimated 2 million hospitalized patients in the U.S. annually with serious adverse drug responses. These scenarios encompass both therapeutic uses, such as drug toxicity, where even standard dosages can lead to severe central nervous system depression, and non-therapeutic exposures, including accidental ingestion by children, and environmental and occupational exposures.Unintentional poisonings often involve exploratory...

Drug Control Governance: Regulatory Bodies and Their Impact
629
Drug control governance involves the oversight and regulation of pharmaceuticals to ensure their safety and efficacy while preventing illegal drug use and trafficking. Regulatory bodies, including the US Food and Drug Administration (FDA) and the European Union's European Medicines Agency (EMA), play a central role in this process. These agencies evaluate the safety and efficacy of drugs before they can be marketed. They fund clinical trials and assess the benefits and risks associated with...

Drug Toxicity: Risk factors
88
Adverse Drug Reactions (ADRs) are potential complications that arise during pharmacotherapy, influenced by multiple risk factors. Age plays a significant role; both neonates and the elderly are at heightened risk due to their respective immature and diminished metabolic and elimination processes. Gender also impacts ADRs, with females experiencing a 1.5 to 1.7-fold greater risk than males, which may be linked to pharmacokinetic, pharmacodynamic, and hormonal differences. Notably, neonates, the...

Drug Regulation

Drug regulation encompasses the management of drug usage by evaluating its safety and efficacy through assessments conducted by regulatory authorities. Regrettably, the history of drug regulation is marred by several catastrophic events. One such incident is the Elixir Sulfanilamide tragedy, in which the toxic compound diethyl glycol was included in a sweet-tasting medication, leading to numerous fatalities. This event prompted the enactment of the Food, Drug, and Cosmetic Act in 1938. Under...
