Poisoning Definition: Medical and Forensic Perspectives
Poisoning is generally defined as a harmful or abnormal condition in the body caused by exposure to an exogenous (external) substance in a dose that is too high for the individual, resulting in medical or social unacceptability. This can occur through various routes such as ingestion, inhalation, injection, or skin contact, and the substance involved can be chemical, physical, or organic in nature Uges2001Gohari2019Vatansever2021+3 MORE.
Types and Causes of Poisoning
Poisoning can be classified based on intent and exposure:
- Accidental Poisoning: Unintentional exposure, often seen in children or due to mishandling of substances.
- Intentional Poisoning: Includes suicide attempts or homicide.
- Iatrogenic Poisoning: Caused by medical errors or excessive prescription of drugs.
- Experimental Poisoning: Involves designer drugs or substances used for non-medical purposes Uges2001Deshmukh2020Prasad2024+1 MORE.

Poisoning can be acute (short-term, high-dose exposure) or chronic (long-term, repeated exposure), with symptoms sometimes appearing only after prolonged contact Deshmukh2020Korobka2023Arpitha2020+1 MORE.
Importance of Understanding Poisoning
Poisoning is a significant public health issue and a leading cause of emergency department visits and deaths worldwide.
