ichthyoallyeinotoxism
Ichthyoallyeinotoxism, or hallucinogenic fish inebriation, comes from eating certain species of fish found in several parts of the tropics, the effects of which are reputed to be similar in some aspects to LSD.
In 2006, two men who ate fish, apparently the Sarpa salpa caught in the Mediterranean were affected by ichthyoallyeinotoxism and experienced hallucinations lasting for several days.
