The programme
Reefer Madness is an American film made in 1936 as Tell Your Children. A school principal warns parents about marijuana, and the story shows young people who try it sliding into a hit-and-run, a killing, suicide and the asylum. It was made outside the Hollywood studios and toured cheap cinemas under several titles for years.
The film is the best-known piece of a much larger campaign. Through the 1930s American newspapers, and the Federal Bureau of Narcotics under Harry J. Anslinger, described cannabis, under the Mexican name marihuana, as a new drug that drove young people to madness and murder. Few of the stories were checked. In 1937 Congress passed the Marihuana Tax Act after short hearings, and legal cannabis, prescriptions included, became practically impossible to get anywhere in the United States; doctors lost it as a medicine five years later.
The picture lasted far longer than the film. It shaped the penalties of the 1950s, travelled to the League of Nations and the United Nations, and still turns up whenever cannabis is debated. Historians call episodes like this a moral panic.
This exhibition takes the claims seriously enough to check them. Each room looks at one part of the story, and every statement links to a source, marked as primary evidence, a documented connection or an interpretation. You can walk through in order or jump to any room.
Room I
Vol. I · No. 1937Every claim fact-checkedPrice: the truth
Newspapers were the campaign's loudest voice. In the 1930s many American papers printed stories of crimes blamed on marijuana, usually without checking them, and officials quoted the papers back to Congress. Here are ten claims of the kind America read then. Open one: behind each is a case file with who made the claim, where it circulated, what was offered as evidence, what later research found, and a verdict.
Room II
A moral panic is rarely one person's work. Here the press, one federal official, a single murder case, a magazine article, a bill and a film fed each other: the papers gave Anslinger his stories, he gave Congress his file of cases, and the film arrived as the law took effect. Read it from the top: each step is dated, coloured by who acted, and joined to the next by what the record shows happened. Stories that are often told but not documented are set apart in their own panel.

The fear becomes local law
The first American ban to draw on the belief that marijuana causes madness and violence. Western states follow over the next twenty years.
History →The states act first; then Washington gets an agency
Harry J. Anslinger becomes its first commissioner. From 1931 he tells the press that criminals use the drug for courage, and from 1934 he treats it as a serious threat.
History →
He collects cases from newspapers and local officials
In Tampa, Victor Licata kills his family with an axe. A Florida official's letter brings the story to Anslinger; marijuana is not in Licata's psychiatric record.
History →
Cases like this become the evidence for a federal law
H.R. 6385, drafted by the Treasury's general counsel Herman Oliphant, taxes every sale so heavily that legal supply becomes impractical.
History →
The bill goes to a committee hearing
Anslinger's evidence is largely newspaper clippings and anecdotes. The American Medical Association's counsel, William Woodward, is the only witness against the bill.
History →
Anslinger takes the same cases to the public
Anslinger's article in The American Magazine, with Licata as its centrepiece, reaches millions of readers.
History →
Congress passes the bill with little debate
Federal law takes effect. The first arrests come within days.
History →
On screen, the warnings arrive after the law
A melodrama of ruined youth, reissued by the exploitation producer Dwain Esper. It spread the fear further, but it came too late to make the law.

Room III
Reefer Madness was not alone. The Hollywood studios' Production Code, enforced from 1934, barred showing the drug trade, so the drug film belonged to independents who took their prints from town to town and sold the forbidden as a warning. Six of them survive in the public domain. Here is the bill: every one of them can be run in this theatre.

“Lila Leeds' own story”
Sam Newfield, as Sherman Scott
Made to cash in on the 1948 arrest of Robert Mitchum and Lila Leeds, starring Leeds herself as a showgirl ruined by marijuana. The showman Kroger Babb reissued it as The Devil's Weed and Wild Weed.
The Production Code, enforced from 1934, kept the drug trade off Hollywood's screens. The subject went to small independents with no stars and tiny budgets.
A written foreword, or a lecturer on stage, presented the film as education for parents. It was the excuse that let a sensational subject past local censors.
Prints travelled with their own showmen, who rented a cinema for a few days, advertised hard, and moved on before word of mouth caught up.
The films are in the public domain and play from the Internet Archive only when you run them. On roadshows: Eric Schaefer — “Bold! Daring! Shocking! True!”: A History of Exploitation Films, 1919–1959 (1999). The Production Code: Britannica — Motion Picture Production Code, and its drug rule in our history.
Room IV
The films lived on their posters. Exploitation distributors had no stars to sell, so the poster sold the subject: big type, hot colours, a woman in danger and a promise of the forbidden, wrapped in a warning. The same tricks moved onto the covers of the cheap paperbacks of the 1950s. Pick a device to see how often it was used, and open any poster to look closer.
Every poster here, from the 1930s to the 1950s.

The films were fiction; the sentences were not. A docket of people the law caught, and of what the law came to demand, with each sentence drawn to scale on the bars: every step to the right is ten times longer.
In the act's first three months agents made 369 seizures. In about half of the cases of the next few years the person held less than an ounce and no sale was alleged.

A warning becomes a joke, and then a word. The film failed as a warning, but its title did not: once students had laughed at it, “reefer madness” became the name for any drug scare built on fear rather than evidence, and it is used more today than when the film was new.
Point at a year. Before 1971 the phrase barely appears; the year Stroup began showing the film, it jumps.

Nothing disappears behind the story. Here is every document, connection and reading the exhibition rests on. Primary evidence is a document from the time itself, such as a film, a speech or a report. A documented connection is something historians have shown from the record. An interpretation is a reading or a popular story, some of them repeated far more often than they are proven.
