It is derived from the word poison and is commonly used in medical, biochemical, and toxicological contexts to describe adverse interactions between a substance and a living organism. Poisoning is sometimes used as a method of self-harm and of suicide, particularly in cases of intentional self-poisoning among individuals experiencing suicidal ideation. According to Time Magazine, self-poisoning is one of the leading methods of suicide attempts among adolescents, and has been identified as the third-leading cause of suicide-related deaths in this age group.
