Since many European colonial port settlements gained competitive edge principally by lowering or abolishing trade tariffs altogether, the funding for public works and town building had to be raised through other means. The narcotic trade offered an easy solution, although the moral quandary would ultimately lead to widespread condemnation from the early 20th century onwards. The story of this shift is the focus of Diana S. Kim's monographic study on the rise of opium prohibition across Southeast Asia. Empire of Vices tracks the story of the changes in governmental and public perception of opium as a unfolding drama across three European colonies: Burma, Malaya and Indochina. To contextualise the significance of opium's reverie inducing signifiance, Kim notes that more than 50 percent of colonial taxes in the British and French colonies of Southeast Asia came from the sale of opium to local inhabitants. In a sense, Kim notes that the legitimacy of the trade was a felicitous alignment of 'the fiscal might and moral right of imperial rule'. During this period, opium was largely seen as a drug that delivers a state of euphoria or other enhanced mood. At times, it was also spoken of positively for its ability to suppress pain as well as induce relaxation, drowsiness, and sedation. Yet, despite the positive health endorsement that opium initially received and its seeming economic indispensability, public perception and colonial administrative policy about the narcotic took a drastic turn at the turn of the century towards [End Page 203] condemnation. By then, the narcotic addictive and debilitating properties became increasingly pronounced and a new moral consensus could no longer justify the trading of opium as a reliable source of public revenue. New strides were made by the very same power to condemn the social danger of the drug. What might account for this change of heart? This is where Kim's Empires of Vices offers a much-needed re-examination of the history of opium prohibition. It is a topic that has acquired general familiarity, although how the story of opium has been told is often conveyed through the pathos of tragedy. Kim eschews these moral theatrics, focusing instead on the how rather than the why. If the why is largely a moral question, the how is a historical one. In turn, story of opium told through this book is not a straightforward didactic story about revenue extraction and social control. The problem Kim sets before herself are two-fold. First, she attempts to make sense of the uneven development of this shared reform across the region by complicating the conventional narrative that changes in colonial policies were simply following metropolitan directives or were mediated by transnational social and religious activists. Second, Kim has set her sights on producing a more satisfying and humanistic account of why the colonial state was willing to abandon its key source of revenue, given that the political economy of colonial enterprises were aimed at maximising profits. In setting out to build up our understanding of opium monopolies in all their complexities, Kim creates a scaffold for the unfolding drama using what she calls a layered comparative approach. At the most direct level, the scaffolding offers a way to iron out discrepancies in sources that a historian is limited to when working across different colonial contexts. Such discrepancies are reasons why comparative research is often thought of as a challenging task. Yet, when comparisons are structured as layers, it functions as a narrative device as well. In this way, Kim's comparative approach also propels a wide range of rich and complex historical sources, ranging from colonial policy papers to literary texts, along a chronological vector. The central topic of the book was the gradual establishment of opium monopolies from 1890s...
