在某种意义上说,选择“美沙酮维持治疗过程中的脱失问题”作为研究选题,纯属偶然。因为原先所实施的一些项目主要是性行为干预,并没有直接接触多少参加美沙酮维持治疗的吸毒人群,对于美沙酮的药理学知识更是一无所知,所以,对于人类学者而言,这是一个非常具有挑战性的选题。 In a sense, it is purely accidental to choose the topic of “loss of care in the course of methadone maintenance” as a research topic. Because some of the previously implemented projects are mainly sexual interventions and do not have direct contact with the number of drug addicts participating in methadone maintenance treatment, there is no knowledge of the pharmacological knowledge of methadone. Therefore, for anthropologists, this is a Very challenging topics.
