If you ever have the chance go to a coffeeshop somewhere else than Amsterdam if you didn't already did that.
Amsterdam is nice and lovely but you also must check the local coffeeshops in smaller city's if you have the chance.
You can have maybe max 5 grams,not like Amsterdam,they are more stricter 
But the weed is very good and not so pricy
In the 90's we went many many times to those shops.in Belgium where I lived it was 30 min drive with the car and you was in Holland.
We hopped from shop to shop to stock up on supplies,it was such a fun time.
We went mostly to Maastricht but they have the weed pas now.
It means you can't enter a coffeeshop in Maastricht of you don't live in the Netherlands ,it's since 2012 unfortunately
We went to other cities aswel like Eindhoven , Rotterdam, Tilburg,Nijmegen, and I totally recommend Tilburg and especially Nijmegen.
They have very good shops with small prices for complete bangers.
The dreadlock,jetset t kunstje are all very nice shops in Nijmegen
We always smoked in the car on our way,we smoked in the shop,we bought space muffins and ate them and we smoked again on our way home.
Those muffins where always very strong,we bought them in the dreadlock.
It was always very fun as I remember,very stoned.
