The hidden Web is used for the anonymous sale of drugs, and with the UK Psychoactive Substances Act, 2016, implemented on May 26th 2016; it could increase as a platform for obtaining new psychoactive substances (NPS). This study aims to describe the NPS market on the visible and hidden Web preban, and assess whether the hidden Web is a likely place for the sale of NPS postban.
Data collection of 113 online shops took place in October 2015. Data collection of 22 cryptomarkets took place every 2 months from October 2015 to 2016 as part of the CASSANDRA project.
All online shops with a UK domain location sold NPS that were uncontrolled by the UK Misuse of Drugs Act, 1971, and closed after the ban. Of the cryptomarkets analysed, the total number of vendors selling NPS, number of substances, and listings advertised, all increased over the year. The majority of the NPS advertised on the hidden Web were phenethylamines and cathinones, yet the majority of uncontrolled NPS were synthetic cannabinoids.
Vendors selling and availability of NPS increased over the 12 months of data collection. Potential displacement from the visible Web to hidden Web should be taken into consideration.
深网被用于匿名销售毒品，随着2016年5月26日《2016年英国精神活性物质法案》的实施，它可能会成为获取新型精神活性物质（NPS）的平台。本研究旨在描述禁令实施前深网和明网的新型精神活性物质市场，并评估禁令实施后深网是否可能成为新型精神活性物质的销售场所。
2015年10月对113家在线商店进行了数据收集。作为卡珊德拉项目的一部分，从2015年10月到2016年，每两个月对22个加密市场进行一次数据收集。
所有英国域名的在线商店都销售不受1971年《英国滥用毒品法案》管制的新型精神活性物质，禁令实施后这些商店关闭。在分析的加密市场中，销售新型精神活性物质的供应商总数、物质数量和广告列表在这一年中都有所增加。深网上广告的新型精神活性物质大多是苯乙胺类和卡西酮类，但大多数不受管制的新型精神活性物质是合成大麻素。
在为期12个月的数据收集期间，销售新型精神活性物质的供应商和可得性都有所增加。应考虑到从明网向深网的潜在转移。
