Opium smoking in the Chinese manner arrived in Southeast Asia with Chinese immigrants and traders. By the 19th century, the capitals of Europe's Southeast Asian colonies all had bustling Chinese quarters. From Rangoon to Batavia to Saigon to Manila, it didn't take long for opium smoking to catch on in popularity with the native populations. In most cases, the colonial powers sought to control and tax the opium trade, allowing smoking to go on as long as it was profitable. Southeast Asian smokers for the most part used Chinese-made pipes, lamps and other accoutrements. The honorable exception were the Vietnamese who were famed for their fabulous works of art in silver. Only in Vietnam did opium accoutrements deviate from the Chinese model, and the Vietnamese developed their own style of lamps, tools, trays, and rituals of smoking.
