Nah. most people just dont give a shit, but cops CAN fine you like 40 euros for smoking that shit in public but it hasnt happened to me in Amsterdam, yet :P
But its true that around the nice(r) restaurants/bars/hotels it wiser not to start toking away, theres always the chance of some...
I've been around, toking mostly :P
U know what else is fun, shrooming in Amsterdam, ive done it like 5 times now with a bunch of friends, we just eat the shrooms somewhere on a bench (out in public of course) and then we walk around amsterdam for around 4 hours completely fuked off our asses...
thats asking a lot, theres so many good coffeeshops and stuff :P
Some of the better ones are: The Bulldog, De Dampkring, La Canna (sp?), and The Grasshopper.
Be sure to tell me the dates that y'all are coming on. We gotta hook up and I'll show you around all the good coffeeshops and smart(shroom)shops in and around Amsterdam.
