I've lived in the Netherlands for many years.
And weed and other so-called soft drugs are legal.
If you compare the problems weed is causing in the Netherlands to for instance the UK or America, they have far less problems with it.
Because of it being legal, it is far less interesting to do it.
But when you want to do it, and you go buy it.
You don't have to find some drug dealer who will introduce you to other drugs and dangers. You go to a coffeeshop, and you get guaranteed quality, nothing in it that is not supposed to be in it. And the seller will give you advise, especially if you are a tourist.
Tourists are the ones that are creating the most problems with the weed. They mix it with alcohol or smoke too much.
The dried magic mushrooms are illegal now because of yet another accident with some tourist, abusing the stuff and jumping out of a window.
Dutch people in general know how to use the drugs in a safe way.
And their government is earning lots of money because of the tax on it and the expensive permits the coffeeshops need to buy. Also it is illegal to grow more than two plants, so people just buy it in the coffeeshop.
