Context and Definitions
Combined Drug Toxicity
Combined drug toxicity occurs when multiple substances interact in the body in ways that amplify their effects, sometimes leading to respiratory depression or cardiac events even when each drug is within a typical therapeutic range. This is a common factor in accidental overdose deaths, particularly when prescription opioids, benzodiazepines, and alcohol are involved.
Accidental Overdose
An accidental overdose is an unintended fatal or nonfatal ingestion of one or more substances. It differs from intentional self-harm when evidence indicates no deliberate purpose to die. Coroners use investigation findings, toxicology, and circumstances to classify drug-related deaths as accidental, suicide, or undetermined.
