More can be written, but you might like to start with "How involved was the CIA in the crack epidemic? Is this primarily an urban legend or grounded in truth? Is there any substance to the charge that they deliberately funneled the drug to inner city neighborhoods in the 1980s?". Answers in the discussion are given by /u/veemondumps, tiredstars, and ThanklessAmputation. Unusually, the top (in the sense of "sort by top") response (by /u/IAmAHat_AMAA) has links to previous discussions, but its top reply (by /u/deepsoulfunk) begins "Man, those answers have a troubling level of variety", leading into a discussion of the historiography.

This is not to discourage discussion. More questions, data and debate are welcome.
