Depends here in Amsterdam, we have too many coffeeshops, some prices are higher then the other one, depends if your in the "centrum" where are much tourists are located. the prices their are for sure higher. We call them Touristshopsalot of them sells shit.
Theres a few good coffeeshops here I'd say, The Bulldog, Tweede Kamer, Boerejongens( was my favourite one )
Anyways I stopped smoking, had my own weedplants aswell back in the days.
