I used to work in a "coffeeshop" in Maastricht, The Netherlands selling pot,until politicians decided that no foreign people were allowed in anymore, only local residents. I had old sick people crying in front of me, that they had no safe place to buy their medicines (Belgium and Germany was nothing allowed at the time) and they had to go buy on the streets, not knowing what they would get... I myself (after my contract ended) was not allowed in anymore, even tho I'm Dutch and only lived 30km into Belgium... They do what they want, as long as we let them do it.
