This was a health emergency of maximum gravity, comparable to the outbreak of AIDS in the early 1980s. The tepid response had to do with how drugs were tied up with race and class.

Unlike blacks in the decades after the Vietnam War, twenty-first-century suburban and rural whites were not protagonists of the nation’s official moral narrative. Indeed, they barely figured in it.
