As an aspiring drug geographer, I thoroughly enjoyed this read. Spillane's in-depth examination of medical journals, newspapers, legal records, correspondence between professionals, and patent medicine advertisements provide valuable insights into how perceptions about cocaine changed from a panacea of the modern "brain worker" into a hedonistic vice of the lower class. He connects the moralistic, political, and only partially scientific nature of contemporary anti-drug laws with progressive era themes of moral panic entrenched in classism and racism. In an era where patent medicines and tonics containing a wide variety of intoxicating substances were publicly available, he situates cocaine use within broader commercial and regulatory transformations—rather than as an isolated phenomenon. I highly recommend this book for those interested in the political economy of intoxicants and drug prohibition.
