Habit Forming, Drug Addiction in America 1776-1914 from Oxford University Press was published December 2022. It is available in hardcover, paperback and eBook. Audio version coming February 2023. Advance praise: "Most US drug histories begin with Richard Nixon. Elizabeth Kelly Gray boldly begins hers with Benjamin Franklin. She brings fresh, unusual sources to bear on a story that runs from the Revolution to the 1914 Harrison Narcotic Act, from laudanum to heroin."
David Courtwright, author of The Age of Addiction
