What Is a Drug Overdose?
A drug overdose happens when a person takes more of a substance than their body can process. This can involve prescription drugs, illicit drugs, alcohol, or a combination of substances, and the result is a dangerous physiological overload that disrupts critical bodily functions, including breathing, heart function, and brain activity. Overdoses can occur accidentally, through a miscalculation of dosage or an unexpected increase in a substance’s potency, or they can result from intentional misuse. In either case, the medical consequences can be severe, irreversible, or fatal without immediate intervention.
The risk of overdose has increased significantly in recent years due to the widespread presence of illicit fentanyl in the drug supply. Fentanyl is a synthetic opioid that is many times more potent than heroin or morphine, and it is now found in counterfeit pills and mixed into other substances, including cocaine, methamphetamine, and benzodiazepines. Many people who overdosed had no idea the substance they took contained fentanyl at all. According to the CDC, synthetic opioids, including fentanyl, are now the most common drugs involved in drug overdose deaths in the United States.
