The legal cannabis industry is budding before our eyes. In just under three months, thanks to the passage of the Cannabis Act by our neighbor to the north, adults will be able to legally purchase recreational marijuana. In fact, when the green flag officially waves on Oct. 17, it'll allow Canada to become the first industrialized nation in the world to allow the sale of adult-use cannabis.We've also witnessed big changes to the south, with Mexico giving the green light to medical cannabis in June 2017.
