The global advancements we have seen over the last few years have been nothing less than impressive, and next month we will witness a historic milestone when Canada becomes the first G7 country to legalize recreational marijuana and launches sales on October 17th. Over the next decade, global spending on legal marijuana is forecast to hit nearly $60 billion, according to a report from ArcView Market Research.
