Prior research has documented the availability of drugs on many Tor Network websites, with the Internet playing a particularly vital role in the global new psychoactive substances (NPS) market. The primary objective of this research was to document types of NPS for sale on the largest operating Tor site (Agora) over a period of four months. Secondary objectives were to analyze countries and vendors sourcing NPS on Agora. Data from Agora were collected in February and June 2015. The number of total advertisements on Agora increased from 20,742 to 27,431 over the four months, while the number of NPS advertisements increased from 2,205 to 2,271 and the number of vendors increased from 157 to 288. The composition of NPS listings and source countries for NPS advertised on Agora diversified over time. Advertisements for ketamine and unclassified NPS experienced substantial growth, while the availability of phenethylamines decreased. However, phenethylamines remained the most frequently advertised NPS type. China and the U.S. were found to be the top two countries by volume selling NPS on Agora over the fpir months, but the number of countries identified as advertising NPS increased by nearly 43%. The United States housed the most NPS vendors.
先前的研究记录了许多暗网网站上毒品的可得性，互联网在全球新型精神活性物质（NPS）市场中发挥着尤为重要的作用。本研究的主要目的是记录在运营时间最长的暗网网站（阿格拉市场）上四个月内出售的新型精神活性物质的种类。次要目的是分析在阿格拉市场上提供新型精神活性物质的国家和供应商。阿格拉市场的数据于2015年2月和6月收集。在这四个月里，阿格拉市场上的广告总数从20,742条增加到27,431条，而新型精神活性物质的广告数量从2,205条增加到2,271条，供应商数量从157个增加到288个。随着时间的推移，阿格拉市场上列出的新型精神活性物质的构成以及所售新型精神活性物质的来源国变得多样化。氯胺酮和未分类的新型精神活性物质的广告大幅增长，而苯乙胺类物质的可得性则有所下降。然而，苯乙胺类物质仍然是广告中出现频率最高的新型精神活性物质类型。在这四个月里，中国和美国被发现是阿格拉市场上按销量排名前两位的新型精神活性物质销售国，但被确定为宣传新型精神活性物质的国家数量增加了近43%。美国拥有最多的新型精神活性物质供应商。
