Drug Overdose - Symptoms, Causes, Treatment & Prevention

Overview

A drug overdose occurs when a person consumes a toxic amount of one or more substances, leading to life-threatening physical reactions. This can involve prescription medications (like opioids or sedatives), illegal drugs (such as heroin or cocaine), or over-the-counter products. Overdoses may be intentional or accidental.

Who it affects: Overdoses impact people across all demographics. In the U.S., adults aged 25–54 have the highest rates. Those with substance use disorders, chronic pain, mental health conditions (especially depression), or a history of overdose are at elevated risk.

Prevalence: Drug overdoses have reached epidemic levels globally. In the United States:

• Over 106,000 people died from drug-involved overdoses in 2021 (CDC, 2023).
• Opioids accounted for 75% of overdose deaths in 2022 (NIDA).
• Overdose deaths increased by 50% globally between 2009 and 2019 (WHO).

Symptoms

• Benzodiazepines (e.g., Xanax): Severe drowsiness, slurred speech, confusion.
