Again, racism was part of the charge against marijuana, as newspapers in 1934 editorialized: "Marihuana influences Negroes to look at white people in the eye, step on white men's shadows and look at a white woman twice."
Two other fear-tactic rumors started to spread: one, that Mexicans, Blacks and other foreigners were snaring white children with marijuana; and two, the story of the "assassins." Early stories of Marco Polo had told of "hasheesh-eaters" or hashashin, from which derived the term "assassin." In the original stories, these professional killers were given large doses of hashish and brought to the ruler's garden (to give them a glimpse of the paradise that awaited them upon successful completion of their mission). Then, after the effects of the drug disappeared, the assassin would fulfill his ruler's wishes with cool, calculating loyalty.
By the 1930s, the story had changed. Dr. A. E. Fossier wrote in the 1931 New Orleans Medical and Surgical Journal: "Under the influence of hashish those fanatics would madly rush at their enemies, and ruthlessly massacre every one within their grasp." Within a very short time, marijuana started being linked to violent behavior.
Successful assassins...on pot.
