Heroin thats 100% pure and turns blue when u put some chemical to it. It could be smoked because it's pure enough as opposed to injected. Frank Lucas used it as the brand name for the heroin he was selling during the late 60's and early 70's. He made millions off of this because he was able to cut off the middle men and go directly to the source in vietnam to buy it. Jay-z also made a song called "Blue Magic" on his soundtrack "American Gangster" based off the movie.
"Blue Magic, that's a brand name, like pepsi. That's a brand name, I stand behind it, I guarantee it. They know that even if they don't know me any more than they know the chairman of General Mills"

A hair grease that a lot of black grandmothers and mothers swear by. Usually used in excess, and most often applied before the hot comb is used.
Often seen on the heads of little girls.
Tacky feel to it.
"Girl, go get that blue magic so i can run this hot comb through ya hair!"

Maybe the greatest non-Thom Bell or Gamble-Huff produced Philly Soul Act of the 1970s, led by the sweeet songwriting wizard Ted Mills. A lot better for you than the stuff described in other definitions

Blue Magic - brand name for 100% pure cocaine created by Frank Lucas throughout the 60's and 70's. He was the first to sell 100% pure cocaine for half the price of cut cocaine. "Cut" being another way of saying diluted. He named it Blue Magic because it was like magic, at least to the addicts that used it because it was pure or uncut. It did things that "cut" cocaine couldn't and no else dared to sell pure.

Blue Magic - song written by Jay-Z for American Gangsta Soundtrack

Blue Magic is a brand name for hair grease, use mostly by blacks for the conditioning of their hair or also referred to as hair conditioner.
Blue Magic was the No.# 1 drug preferred then by all addicts

The name for one of Jay-Z's best works. Only if you are a fan.

Hair grease, not exactly one of the best types of hair greases to use. Some real tacky stuff.
