I don't think its from today. I can't find anything in English, there are a few articles in dutch like this one.
http://www.rtl.nl/components/actueel/rt ... n-2015.xmlMy best guess from the articles in dutch is that 70 of Amsterdam's 220 coffee shops will close by 2015, which includes 26 of the 76 coffee shops in or near the Wallen, because they are within 350 yards from a school. However, the coffee shops can have priority on Amsterdam locations that become available outside the 350 yard boundary, so they have a good chance of merely relocating rather than closing.
