Cannabis is no more a marginal issue in culture, but neither in economy. Legalization moves millions of dollars in revenues between goods trading and new jobs which are revitalizing some activities that were thought gone forever. It is a great option for investment as well.
Besides, governments realised that they could raise lots of money in taxes in those districts where legalization allows use and growing, wether recreational or medical use (certain states in the US, Israel and Uruguay, to name a few). Seeds, plants, crops, by-products, biotech labs, paper, pipes, oils and all the stuff for growing and harvest are making an impact in the real economy.
Left aside the cannabis trading fairs which are attracting more people in more countries -which add on the tourism industry-, cannabis does not only moves money, it also moves expectations. That’s why cannabis-focused companies (labs, especially, but also real estate developers and by-products manufacturers) are moving on to attract investors. That means that they are inviting them to diversify into the cannabis boom -not only looking to be cool, but for profit as well- to get along with an industry that has an enormous future -and a vigorous present.
