An urban legend states that the dried skin of the banana fruit contains the fictitious substance "bananadine", and is hallucinogenic when smoked. It dates back to an article an underground newspaper 1967, and became widespread after it was included in The Anarchist Cookbook in 1970. This legend is not entirely without merit: bananas contain tryptophan which, when ingested, increases levels of serotonin in the body (the same effect as Prozac). However, it's debatable whether smoking tryptophan would be successful as a method of administration.
