i heard prague is FUNNNNNNNNNN (czech republic). never been to europe yet so i cant really say. i heard in amsterdam that you smoke in like the cafes/coffee shops or w/e you call em (sorry never been there). also some of the hostels will let you smoke in the lobby/hang out room i've heard. someone told me that if you walk around and do it they might know your a tourist or it is kind of looked down upon to be OBVIOUSLY realllyyyy stoned walking down the streets. you can find some info on amsterdam sites or message boards
