Datura poisoning--the Angel's Trumpet.
A group of seven ate flowers of Datura arborea ("The Angel's Trumpet" or "Trumpet Lilies") and suffered severe hallucinations. One member of the group drowned in shallow water while suffering from these effects. Although poisoning with related species is common, poisoning with this plant is rare, perhaps due to its terrifying rather than pleasurable hallucinogenic effect.
