Atlas Documentary Films recently published a short documentary about the Dutch Coffeeshop system. It contains multiple interviews with very important people of the amsterdam coffeeshop scene. It features Wernard Bruining the owner of Mellow Yellow, Kurt van Es a dutch writer, a worker at one of the Kadinsky coffeeshops and Michael Veling owner of the 420 Cafe. So make sure to take a look and see that even the dutch system has a fault, the achterdeur is still an issue.
In the end Wernard Bruining closes the short film with the words the war is over but see for yourself.
