为了解吸毒人群的流行病学特征，采用问卷式方法进行调查，结果：１４１例吸毒者年龄在１６～３６岁之间，平均年龄为２３７岁，最早吸毒年龄男性为１３岁，女性为１６岁，平均２１１岁；吸毒者以本地人较多（９５７％，１３５／１４１），文化程度较低，初中及以下者８０例（５６７％，８０／１４１），以待业人员为主（５８２％，８２／１４１）；吸毒方式主要是吹龙和静脉注射二种，以静脉注射者占大多数（８７２％，１２３／１４１），６５０％（８０／１２３）的吸毒者有共用注射器史，吸食毒品时间以二年的为多（４１１％，５８／１４１），吸食毒品以每日０３３克（一啡）为多（５９６％，８４／１４１）；１１１例有婚外性生活史（７８７％，１１１／１４１），性生活时未使用避孕套的有８６例（７７５％，８６／１１１），其中男性６７例、女性１９例；戒毒后的复吸率７２３％（１０２／１４１）。作者就上述情况进行了相应的分析讨论，为口岸今后监测、预防和控制传染病提供科学依据或参考。 In order to understand the epidemiological characteristics of drug addicts, a questionnaire survey was conducted.
