The Netherlands is an interesting case. Despite amphetamine, MDMA, etc. being illegal, The Hague has turned a blind eye to massive industrial production farms in the south. At one point, the Netherlands almost held a monopoly on the world's MDMA production. Rumors of conspiracy suggest it's intentional, but the end result is the same. Many of these drugs are de facto legal, if not de jure. Of course, this was the landscape some decades ago. It's been changing. Mexican cartels are starting to elbow in, and it's been causing "problems". Watching how the government reacts to the evolving ecosystem is going to be intriguing.
