In my country (France), I know some guys who actually "skin-pop" cocaine on purpose.
It's not a real trend, I don't inject (any kind of injections, but I don't care if my friends shoot up at my place, I really don't give a f... it's just that I don't want to do it myself, partially thanks to bluelight) but I know a bunch of people who do (inject), since I work in a "Caruud" (places where we do harm reduction), and most cocaine users IV it.
But several small groups of (generally young, about 20 years old, go to festivals to do MDMA/XTC, have rich parents but like to live "wild", dress like poor druggies and sleep and beg on the street, calling people who don't give them coins "hey fucking bourgeois fuck off anarchy man", go back to there parent's house during the winter while they friends who are actually poor have to sleep in the streets, etc etc) users use the skin-popping method for coke...
I always tell them that it's very dangerous, and that they should either snort it or, if they really use a rig, to IV it but they are not the brightest bunch.
It's always "but SC injections aren't as serious as IV or even IM, dude I don't wanna be a junky, it's not as hardcore or dangerous as really shooting up here I'm just penetrating the skin a little bit, blababullshitbla".
You can imagine my reaction. ABSCESSES + you're using a needle anyway so don't think your better than people who IM or IV.
Sorry for the rant mesdames et messieurs, but I remembered them when I saw this thread.... also that oil makes me chatty =)
