Key findings:

• From 1^st June 2021 to 31^st May 2022, 27 cryptomarkets were monitored weekly, of which 11 closed before the end of the reporting period. We began monitoring 14 new cryptomarkets during this period.
• In the final month of reporting, DarkFox, AlphaBay, ASAP, Versus and Bohemia were the largest cryptomarkets.
• The number of drug listings across all monitored cryptomarkets increased by 65% in May 2022 (n= 45,733) as compared to June 2021 (n= 29,047), with increases noted across all drug classes. More recently, a 16% decline in total drug listings was observed from April to May 2022.
• The largest percentage of listings from June 2021 to May 2022 were for cannabis (31%), followed by benzodiazepines (7.6%), cocaine (7.5%), MDMA (7.5%), meth/amphetamine (illicit) (6.2%), and PIEDs/weight loss (6.0%).
• The market share of the different drug classes (i.e., percentage of total drug listings) remained relatively stable over the monitoring period.
• The biggest increase was observed in the percentage of listings selling hallucinogenic mushrooms, which increased by 1.4% from 2.3% of all drug listings in June 2021 to 3.8% in May 2022. The greatest percentage decrease was observed for other medicines (4.5% of all drug listings in June 2021 to 3.6% in May 2022).
