Why is marijuana illegal? Do a quick internet search and you’ll find a series of generally related answers: racism, fear, corporate profits, yellow journalism, ignorant and incompetent legislators, and bureaucratic preservation. Almost all of these are also tied to one man: Harry J. Anslinger, Commissioner of the Federal Bureau of Narcotics from 1930-1962. While these issues are critically important to consider, they help explain only portions of our nation’s marijuana prohibition story. Indeed, in part one of this series I examined the origins of cannabis regulations dating back to the mid-nineteenth century. These state level statutes demonstrate a clear, historical precedent for medicinal cannabis legislation in the United States, driven by the concerns of medical doctors and pharmacists seeking both their own professional authority and consumer protections in the marketplace. My objective is to suggest that these early developments demonstrate a far longer and more complex history of cannabis regulation than most existing versions of the story suggest, especially those readily available on the internet. It’s not that those internet versions of marijuana prohibition are entirely wrong; it’s that they often sustain a sensational narrative that misses critical components of this longer history and the original scholarship from which they are derived.
