The Emperor Wears No Clothes is a book written by Jack Herer. Starting in 1973, Jack Herer took the advice of his friend "Captain" Ed Adair and began compiling tidbits of information about cannabis and its numerous uses. After a dozen years of collecting and compiling historical data, Herer first published his work as The Emperor Wears No Clothes in 1985. The eleventh edition was published in November 2000, and the book continues to be cited in cannabis rescheduling and re-legalization efforts.
The book, backed by H.E.M.P. (America), Hanf Haus (Germany), Sensi Seeds/Hash, Marihuana & Hemp Museum, Amsterdam, (Netherlands), and T.H.C., the Texas Hemp Campaign (America), offers $50,000 to anyone who can disprove the claims made within. Quoting from the book's back cover:
The title of the book alludes to the classic fairy tale "The Emperor's New Clothes" by Hans Christian Andersen. Herer uses Andersen's story as an allegory for the current prohibition of cannabis.
European experts on hemp, like Dr. Hayo M.G. van der Werf author of the doctoral thesis Crop physiology of fibre hemp (1994), criticized the book for containing inaccuracies.
