    • Tokyo, Japan has the most expensive cannabis, at 32.66 USD per gram, while Quito, Ecuador has the least expensive marijuana, at 1.34 USD per gram.
    • Based on the average US marijuana tax rates currently implemented, New York City could generate the highest potential tax revenue by legalising weed, with 156.40 million USD per year. New York City also has the highest consumption rate of cannabis, at 77.44 metric tons per year.

      Berlin, Germany, 20/04/2018 – ABCD, a data-driven media campaign outlet, has released new data which reveals the number of marijuana head and growshops in 120 cities around the world. This research, which builds on the 2018 Cannabis Price Index released earlier this year, reveals which locations around the world are ready to embrace cannabis legalisation. The aim of the study is to illustrate the continuous need for legislative reform on cannabis use around the world, and to determine if there are any lessons to be learned from those cities at the forefront of marijuana legalization. By including extra data on the number of head and growshops in each city, this new research can be utilized to indicate which cities are prepared for an imminent cannabis reform, while also highlighting which cities are in opposition of marijuana legalisation.


      The initial study began 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. To calculate how much potential tax a city could make by legalising weed, ABCD investigated how much tax is paid on the most popular brand of cigarettes, as this offers the closest comparison. They then looked at what percentage marijuana is currently taxed in cities where it’s already legalised in the US.


      ABCD decided to conduct the extra research in order to to further the discussion around the medical and recreational use of cannabis, and the potential industry and business opportunities that would follow legalisation. By identifying the number of headshops as well as growshops, this study serves as an indicator to a city’s existing cannabis infrastructure and willingness to accept such reform on a larger scale. As an indicating factor, the more head shops and grow shops a city has, the more positive their state’s and general public’s attitude towards the cannabis-related industry is likely to be.
