To examine the potential of surveys delivered via the World Wide Web (WWW) as a method for reaching hidden populations such as that of nonabusive users of illicit drugs.
Past and current approaches to collecting data from hidden populations were reviewed.
A number of approaches have been used in the past efforts to reach drug users but the use of the WWW has produced the largest sample of successful illicit drug users ever surveyed.
Further application of this approach (WWW) is recommended when hidden populations are surveyed.
研究通过万维网（WWW）进行调查作为接触隐藏人群（如非法药物非滥用使用者）的一种方法的潜力。
回顾了过去和当前从隐藏人群中收集数据的方法。
过去为接触吸毒者采用了多种方法，但利用万维网进行调查获得了有史以来对成功非法药物使用者进行调查的最大样本。
在对隐藏人群进行调查时，建议进一步应用这种方法（万维网）。
