Unfortunately, the marijuana industry—comprised almost entirely of white men—has targeted communities of color, despite promises to the contrary. This should, perhaps, not be surprising: the tobacco and alcohol industries have long targeted such communities. One Johns Hopkins study revealed that predominantly African-American neighborhoods in Baltimore were eight times more likely to have carry-out liquor stores than racially mixed or white neighborhoods. And tobacco companies have historically placed larger amounts of advertising in African-American publications, exposing African-Americans to more cigarette ads than whites, and have marketed more harmful and more addictive products to them.
The marijuana industry is already copying the Big Tobacco playbook in Colorado. There, marijuana use is up overall. And in Denver, pot businesses are concentrated in lower-income, neighborhoods of color—one lower-income neighborhood has a pot business for every 47 residents.
Moreover, in the two years after Colorado legalized marijuana, the number of Hispanic and black kids arrested for marijuana-related offenses rose 29 and 58 percent, respectively. In the same period, the number of white kids being arrested for identical crimes dropped eight percent.
