Many organizations are involved in this cult, including the PDFA, ONDCP, DEA, UN, Republicans, and various pharmaceutical companies, as well as almost all fundie groups. The cult has no official leadership, but the US government and UN share most of the administrative duties.
The cult was founded by Harry J. Anslinger (also first head of the DEA), who was mainly responsible, through the successful use of propaganda, for the national and subsequently global criminalization of marijuana (globally criminalized through U.N. conventions). He was well-known for his racism and violent hatred of jazz, as well as his hypocrisy, reversing his position on the effects of marijuana from the claim that it would make you murderous to the claim that it would make you absolutely useless. This led some to conclude that he was hepped up on goofballs. Some enlightening quotes from him are below.
"There are 100,000 total marijuana smokers in the US, and most are Negroes, Hispanics, Filipinos, and entertainers. Their Satanic music, jazz, and swing, result from marijuana use. This marijuana causes white women to seek sexual relations with Negroes, entertainers, and any others."
"...the primary reason to outlaw marijuana is its effect on the degenerate races." (taken from his testimony to Congress)
"Marijuana is an addictive drug which produces in its users insanity, criminality, and death."
"You smoke a joint and you're likely to kill your brother."
"Marihuana leads to pacifism and communist brainwashing." (1948)
The Church of Voodoo Pharmacology continues to be well known for hypocrisy, racism, and an obsession with marijuana.
