For someone like me, who consumes industrial quantities of codeine (and by that I mean more than several grams a day), it's something that really shocks me. Why the hell is codeine suddenly appearing in rap songs by groups from all over the world in every language you can think of? To find out, I asked BertiMC -- a rapper from Salamanca -- what he thought and his answer was simply, "It's the fashion." And he's right. A fatal fashion started by a guy named Dj Screw, who died of an overdose of codeine mixed with other drugs, which seems to have started a trend, a kind of cult, if you will, within this musical genre.
