Drug Trends has identified, crawled (or ‘scraped’), extracted, categorised and analysed drug listings on cryptomarkets on a weekly basis since 1 February 2014. This bulletin series reports on trends in the availability and type of substances sold on the internet via cryptomarkets over the last 12 months (new bulletin released every four months). The current bulletin focuses on analysis of listings from 1 January 2019 to 31 January 2020.

An accompanying public online interactive data visualisation is available, allowing viewers to interact with data collected over the total monitoring period.

We have supplemented the data visualisations with:

  1. A Bulletin document outlining key findings from 1 January 2019 to 31 January 2020; and
  2. A Methods document outlining the background to this program of work and the methods underpinning data presented.

Key findings

  • From 1 January 2019 to 31 January 2020, 13 cryptomarkets were monitored, and seven cryptomarkets closed down.
  • Dream Market was responsible for 80% of drug listings each week until closure on the 30 April 2019.
  • Cannabis, MDMA, cocaine, benzodiazepines and meth/amphetamine were the five drugs accounting for the greatest percentage of listings (64%).
