Dude go to a club, give some dude ten bucks and that'll get you a couple of lines at least. A brick of hash about the size of a quarter will cost you around 50. This is all euros, by the way.
Hash is way too harsh anyway. I always get a bigass headache, get nauseous and fall asleep...really fucked up though. The stuff grown in the mountains here is much smoother.
True story:
The health department in Milan took a sample of the city sewer drainage and discovered an amount of cocaine in it estimated to the equivalent of 50% of the people there snorted. In other words, if you're in a room with someone in Milan, chances are one of you is snorting coke. Either that or there is a gigantic stockpile of cocaine dumped in the sewers.
