The Problem Opium addiction was prevalent in the United States from the early 1800s to the early 1900s, when about 250,000 opiate-dependent persons lived in the United States [1]. After the Narcotic Act of 1914, opium addiction essentially disappeared from the United States until it reappeared among Indochinese refugees during the last decade [2]. This paper reports on the demographic characteristics and opium use patterns in a group of Asian opium addicts presenting voluntarily for assessment and treatment.
