it is a difference between center of amsterdam and rest of the holland as far i know from my friends there. in center of amsterdam still no changes, but in the rest of holland you cannot buy anything if you are foreigner, you must have holland id card. also, it is not like you buy and smoke on the bar, you must go to special place where you can get high. but, i am talking about rest of the holland, in turistic center of amsterdam nothing changed, maybe just the prices
