Nigeria has the world’s highest rate of cannabis use, with 19.4% of its population aged 15+ having consumed it in the past year.
That statistic offers extra significance given the illegal status of the plant across most of Africa.
Globally, the highest reported rates of use are typically associated with progressive cannabis laws.
Canada (with a nationwide market) and the United States (through various state markets) both have active adult-use cannabis markets, characterized by strong public awareness and widespread support for legalization.
Accordingly, Canada and the United States respectively have the world’s second- and third-highest usage rates of cannabis.
