Joseph Westermeyer (1937–2024) was at the time of original publication based at University of Minnesota. He served as a physician and psychiatrist in Laos from 1965 to 1967. During that time, he worked extensively with various ethnic groups, including the Hmong, and became a leading expert on public health, addiction, and mental health in the region. He famously established a drug treatment center and his research from this period formed the basis of his influential book, Poppies, Pipes, and People: Opium and Its Use in Laos. His work in Laos was foundational for his later career in the USA as a renowned authority on refugee mental health, particularly among the Hmong communities that resettled in Minnesota, California, and other states.
