Seedo says, "The study began first by selecting 120 cities across the world, including locations where cannabis is currently legal, illegal and partially legal, and where marijuana consumption data is available. Then, they looked into the price of weed per gram in each city".

Rates of weed from cities are based on the "crowd-sourced city-level surveys adjusted to World Drug Report 2017 of the United Nations Office on Drugs and Crime, " it added.
