Bananadine

Bananadine is a fictitious psychoactive substance which is supposedly extracted from banana peels. An alleged recipe for its "extraction" from banana peel was originally published in the Berkeley Barb in March 1967. It became more widely known when William Powell reproduced the method in The Anarchist Cookbook in 1970. Powell has since attempted to have the recipe withdrawn. However, as he no longer holds the copyright for the article, he has been unsuccessful in this.

The joke was started by the Yippies to prove that you can't trust the media: they'll print anything anyone tells them.

Researchers at New York University have found that banana peel contains no intoxicating chemicals, and that smoking it produces no physical effect. Over the years, there has been considerable speculation regarding the psychoactive properties of banana skins.
