Hemp for Victory is a black-and-white United States government film made during World War II and released in 1942, explaining the use of hemp, encouraging farmers to grow as much as possible. During World War II, the Marihuana Tax Act of 1937 was lifted briefly to allow for hemp fiber production to create ropes for the U.S. Navy but after the war hem reverted to its de facto illegal status.

The film was made to encourage farmers to grow hemp for the war effort because other industrial fibers, often imported from overseas, were in short supply. The film shows a history of hemp and hemp products, how hemp is grown, and how hemp is processed into ropecloth, cordage and other products.

Before 1989, the film was relatively unknown. The United States government denied ever having made such a film.[2] The United States Department of Agriculture[3] library and the Library of Congress told all interested parties that no such movie was made by the USDA or any branch of the U.S. government. Two VHS copies were recovered and donated to the Library of Congress on 19 May 1989 by Maria FarrowCarl Packard, and Jack Herer.

The only known copy in 1976 was a 3/4″ broadcast quality copy of the film that was originally obtained by William Conde in 1976 from a reporter for the Miami Herald and the Ethiopian Zion Coptic Church of Jamaica. It was given in trust that it would be made available to as many as possible. It was put into the hands of Jack Herer by William Conde during the 1984 Oregon Marijuana Initiative. The film is now available in numerous locations on the Internet.

In July 1989, Jack Herer together with Chris Wright, of the Grassroots Party, attempted to obtain a copy from the National Archives where it was listed, but the curators were unable to locate the film. Subsequently, in May 1990, the founder of The Institute for Hemp, J.T. Birrenbach, recovered a copy of the film from the National Archives. [4] The film was a two-part film the first section being 6:46 the second being 7:16 long. Together the approx 15 minute film detailed the cultivation of cannabis for fiber. This was the first recovery of the film from a government source. This film can now be downloaded from the National Archives.[5]

Hemp for Victory was produced by the US Department of Agriculture and contained scenes from the 1926 silent film Old Ironsides, it is public domain and is freely available for download from the Internet Archive.
