Cannabis use, markets and policy and the effects of Covid-19


Cannabis policy has always been something of great interest to members of the International Society of for the Study of Drug Policy (ISSDP), who have been examining cannabis markets (production and supply, retail trade in legal medical markets, quasi-legal and legal recreational markets and illicit markets, and use) so they were well situated to monitor changes in these markets in the U.S., Canada, and Europe when COVID-19 hit.  In the joint ICARA-ISSDP webinar, we discussed how consumers and markets reacted to COVID, noting that use of cannabis rose despite initial restrictions on the supply. Markets recovered very quickly, swiftly moving on-line, which allowed greater access for many users. Key insights from the ongoing studies of internet market sales and self-reported use will be discussed.
