Poisoning is the harmful effect which occurs when toxic substances are introduced into the body. The term "poisoning" is a derivative of poison, a term describing any chemical substance that may harm or kill a living organism upon ingestion. Poisoning can be brought on by swallowing, inhaling, injecting or absorbing toxins through the skin. Toxicology is the practice and study of symptoms, mechanisms, diagnoses, and treatments correlated to poisoning.
How this connects to Forensic Medicine and Toxicology
The ear, nose and throat form connected sensory and airway systems. Sound conduction, inner-ear transduction, nasal airflow, swallowing and laryngeal function depend on separate structures and cranial nerves, so similar symptoms can arise from different anatomical locations.

What the underlying subject studies
Forensic medicine applies clinical observation and biological science within a legal and ethical framework. Accurate contemporaneous documentation, consent, chain of custody and clear distinction between facts and interpretation are central.
How mechanisms and evidence connect
Toxicology relates exposure to absorption, distribution, mechanism and biological response. Risk depends on the substance, formulation, dose, timing, route and patient factors; a label or symptom alone cannot identify an exposure.
How to develop a sound explanation
Study each topic by separating observations, differential possibilities, limitations of tests and applicable professional duties. Legal procedures vary by jurisdiction and must be verified against current rules.
