That's one of the interesting things I noticed about Amsterdam. It is notorious for the availability of cannabis, but it's very clear that you don't consume in public or around the neighborhood. (Modulo a group of teens I saw passing a joint around in the park). The coffeeshops are clearly intended to contain the drug use. Unlike California where you smell weed everywhere.
There is so much absurd regulation of marijuana in California, that the gray and black markets are still thriving. There is too much demand and not enough legal supply because of bullshit red tape. Making it easier to grow legally is the path to taking organized crime and violence out of it.
