From nineteenth-century opium dens to the war on cocaine and cannabis, and more, Fisher offers a vivid tour of the sites of conflict, along with a convincing case for how the moral discourses and social contexts of the day pit drugs against the law. Bringing this history up to the present, Fisher shows how the racial dynamic has changed dramatically. As harsher penalties swell prisons with mostly nonwhite dealers, antidrug laws have come under renewed scrutiny as a tool of racial oppression. The book closes with an examination of cannabis legalization, driven in part by the movement for racial justice.
