the mysterious history of marijuana (raises more kwestins than it answers)

npr | Marijuana has been intertwined with race and ethnicity in America since well before the word "marijuana" was coined. The drug, , has a disturbing case of multiple personality disorder: It's a go-to pop culture punch line. It's the foundation of a growing recreational and medicinal industry. , it's also the reason for more than half of the drug arrests in the U.S. A deeply disproportionate number of marijuana arrests (the vast majority of which are for possession) befall African-Americans, despite similar rates of usage among whites and blacks, the ACLU says.

Throughout the 19th century, news reports and medical journal articles almost always use the plant's formal name, cannabis. Numerous accounts say that "marijuana" came into popular usage in the U.S. in the early 20th century because anti-cannabis factions wanted to underscore the drug's "Mexican-ness." It was meant to play off of anti-immigrant sentiments.

A common version of the story of the criminalization of pot goes like this: Cannabis was outlawed because various powerful interests (some of which have economic motives to suppress hemp production) were able to craft it into a bogeyman in the popular imagination, by spreading tales of homicidal mania touched off by consumption of the dreaded Mexican "locoweed." Fear of brown people combined with fear of nightmare drugs used by brown people to produce a wave of public action against the "marijuana menace." That combo led to restrictions in state after state, ultimately resulting in federal prohibition.

But this version of the story starts to prompt more questions than answers when you take a close look at the history of the drug in the U.S.: What role did race actually play in the perception of the drug? Are historical accounts of pot usage — including references to Mexican "locoweed" — even talking about the same drug we know as marijuana today? How did the plant and its offshoots get so many darn names (reefer, pot, weed, hashish, dope, ganja, bud, and on and on and on) anyway? And while we're on the subject, how did it come to be called "marijuana"?

Let's start with the race question. Eric Schlosser recounts some of the racially charged history of marijuana in (some of the source material for the best-selling book):

"The political upheaval in Mexico that culminated in the Revolution of 1910 led to a wave of Mexican immigration to states throughout the American Southwest. The prejudices and fears that greeted these peasant immigrants also extended to their traditional means of intoxication: smoking marijuana. Police officers in Texas claimed that marijuana incited violent crimes, aroused a "lust for blood," and gave its users "superhuman strength." Rumors spread that Mexicans were distributing this "killer weed" to unsuspecting American schoolchildren. Sailors and West Indian immigrants brought the practice of smoking marijuana to port cities along the Gulf of Mexico. In New Orleans newspaper articles associated the drug with African-Americans, jazz musicians, prostitutes, and underworld whites. "The Marijuana Menace," as sketched by anti-drug campaigners, was personified by inferior races and social deviants."

In 1937, U.S. Narcotics Commissioner Henry Anslinger testified before Congress in the hearings that would result in the introduction of federal restrictions on marijuana. , Anslinger's testimony included a letter from Floyd Baskette, the city editor of the Alamosa (Colo.) Daily Courier, which said in part, "I wish I could show you what a small marihuana cigaret can do to one of our degenerate Spanish-speaking residents. That's why our problem is so great; the greatest percentage of our population is composed of Spanish-speaking persons, most of who [sic! such an enthusiastic sic!] are low mentally, because of social and racial conditions."

Folks weren't just worrying about Mexicans and jazz musicians, either. "Within the last year we in California have been getting a large influx of Hindoos and they have in turn started quite a demand for cannabis indica," wrote Henry J. Finger, a powerful member of California's State Board of Pharmacy, (page 18). "They are a very undesirable lot and the habit is growing in California very fast; the fear is now that it is not being confined to the Hindoos alone but that they are initiating our whites into this habit."
