LaGuardia Report from 1941 Indicates U.S. Waged Propaganda Campaign Against Cannabis
Back in the 1940s, Frank LaGuardia, mayor of NYC, wanted to test the scare claims made by the anti-drug warriors that created prohibition in the 1930s because he was skeptical. (Many of these same claims are continually recycled.)
His large-scale study and report debunked the claims made by the prohibitionists. Nevertheless, LaGuardia was attacked. It turns out his report was one of a few done at the time (others were in Canada and Great Britain and in the U.S. Army) that indicated there was no danger of physical addiction or physical or mental deterioration for those who smoked over a period of years. You can read LaGuardia's study and conclusion here:

Since the LaGuardia Commission Report, published in 1944, our govt has known that marijuana is nothing like the claims they have made against it to justify prohibition. In spite of this reality, the Boggs Act of 1951 created harsher penalties for possession than this nation had for serial killers and rapists. The reason for this was that marijuana use was considered something done by African and Latin -Americans...and movie stars and musicians.
When a sociology professor published research in the 1950s that debunked misinformation spread by our govt., his phone was tapped, the federal govt (FBN - federal bureau of narcotics) tried to suppress his work and they also tried to get the FBI to find a way to associate this professor with the communist scare of the time. When Canada created a public service documentary that indicated the FBN stereotypes of addicts and drug fiends were lies, this govt. org. sought to ban the film. This professor (of sociology at Indiana University, fwiw) spoke out about this abuse of govt power that sought to interfere with the medical treatment of people with addictions. Finally, the ACLU, the AMA (American Medical Asso.) and the American Bar Asso. spoke out in defense of this professor and this film - and against the govt. lies.
(Out of this experience, an independent org. began that was dedicated to issues of public heath and science, rather than scare campaigns and propaganda. That group eventually merged with the Drug Policy Foundation to create the current Drug Policy Alliance - a group that still works to provide information based upon research and science.)
On its website, the Drug Policy Alliance notes that: Numerous published studies suggest that marijuana has medical value in treating patients with serious illnesses such as AIDS, glaucoma, cancer, multiple sclerosis, epilepsy, and chronic pain.
