Fifty-six addicted "world travelers" were studied at a treatment facility for opium addicts in Laos. They were primarily in their twenties (80%), male (80%), and single (70%). Most had begun narcotic use away from their own country during their travels. A majority were traveling alone, currently living alone, and using narcotic drugs alone. Their addiction at the time of seeking treatment was well established: narcotic drugs comprised their main daily expenditure, they had numerous problems associated with narcotic use, and high doses of methadone were necessary for detoxification.
在老挝一家鸦片成瘾者治疗机构对56名成瘾的“世界旅行者”进行了研究。他们主要是二十多岁（80%），男性（80%），单身（70%）。大多数人在旅行期间开始在国外使用麻醉品。大多数人独自旅行、目前独自生活且独自使用麻醉药品。他们在寻求治疗时成瘾情况已根深蒂固：麻醉药品占其主要日常开支，他们有许多与使用麻醉品相关的问题，且戒毒需要高剂量美沙酮。
