my from southeast michigan, and I have heard so many differant names called for heroin. some that are specific to his region are: Raw, Boy, Dogfood, Brown, Heron (pronounce hair-Ron), and the funniest is Blow. If you came into the city of detroit and asked somebody for "Blow" you're gonna get heroin, not cocaine. it's weird because everyone uses that term for coke. but not here. people will say "i need some blow" or "i need a blow" and they mean they need a pack of dope.
