The maxim of the moment and for the new millennium (at least for now) is that “after 9/11 the world changed.” Focused, amplified, and projected by the media, the September 2001 events have echoed with an apparent immensity and a rending of the global geopolitical fabric that merit comparison with Waterloo in June 1815 and Sarajevo in June 1914. In each case, an epoch is said to have ended, the first by conventional battle in concert with peace conventions that ended several decades of global conflict, the latter two with acts of terrorism that precipitated global wars of vastly differing intensities and probable durations. Each of these turning points in global history has, of course, its own character, dynamics, and contexts, which largely transcend the narrower episodes and scenes that constitute the intersections of drugs, war, and peace. Nevertheless, one of the persistent and little-noticed elements in the history and geography of warfare during the past half millennium has been the role played by psychoactive substances. With the exception of the Sino-British Opium Wars (1830s–1840s), drugs as aids or obstacles, let alone causal factors, of war have been largely overlooked. Yet even a cursory overview, as presented here, should establish the contours of a topic that merits in-depth attention. Here we have only the space to point to some key instances and promising case studies. Future researchers may find these useful points of departure. The three pivotal events noted earlier, plus October 1492 as the antecedent and fourth key moment, mark a fivefold periodization that provides a convenient way of framing the differing historical relations between drugs and warfare. Prior to Europe’s transatlantic expansion and the coeval eruption of capitalism across the globe, the varying articulations between drugs and war were largely local, individual, and particular. With the rise of long-distance trade networks structured by mercantile capitalism, prime commodities such as sugar and tropical spices launched European-based empires and provoked wars from the East Indies to the West Indies, as well as points north and south.
