Not to be confused with comedian Steve Martin, expatriate writer (of guide book sections, mostly, apparently) Steven Martin has just published a really interesting, though at times esoteric, book, Opium Fiend: A 21st Century Slave to a 19th Century Addiction.
Martin's initial addiction is for collecting. Since he was a child, he has collected various objects with varying degrees of obsession. He ends up living in Bangkok and after giving up collecting Southeast Asian textiles, he begins to collect antique opium accoutrements -- pipes, bowls, trays, lamps, various tools, and more.
At first -- and really throughout -- Martin has the passion of a collector. But of course, he dabbles in opium smoking -- first on assignment for an article and then to learn more about the objects that he collects. For years, he smokes (or really, vaporizes) opium casually and infrequently, but eventually the drug sinks its teeth into him. Martin does a great job detailing his addiction, his isolation from social life, his attempts to quit, and the psychological aftermath of kicking (at least provisionally).
Secondarily, Martin vividly depicts parts of Bangkok as well as Vientiane (Laos). He also offers a history of opium smoking and commerce (including the Opium Wars of the 19th century). While this book is a good historical resource -- and Martin runs a consultancy advising film and TV about authentic depictions of opium smoking -- it does not discuss present-day crime and law enforcement around opium, heroin production, smuggling, etc.
