Helsinki, at least is an interesting place. Much like any other capital if you go to certain neighbourhoods you can see drug dealers, drug users (many which are living in shelters) - even in downtown. They kind of blend in, are part of the scenery and on the whole only interact with their "own kind". You might hear some grumbling, shouting, smelly folk on the tram - but they aren't treated with the same contempt at existing as I've seen in other countries.
