For example the local government of Amsterdam is trying to close the window brothels [0] in the cities' Red Light District and many cities now have a policy where they don't grant licences for new coffeeshops and wait for the current licenses to expire [1]. The cited reasons for wanting to close the coffeeshops (too close to schools, within 250 meters) are stupid since every Dutch student rides a bicycle and for my friends it was no big problem during a free hour to bike for a few kilometers to buy and smoke hash or weed. My friends did this many times (none became a worse person for it, either).
