Freon-13 (iirc or 11) was very popular here, it came in an aerosol too, I used it for a couple days straight and after a terryfing session where I lost my senses and read up about freo stopped, some friends (whom I don't see no more since) continued to use it, and what greenbarts describes happened a lot, they did oxi (not oxycontin, that was me, the one who's still here) (for those of you who read the DITM article ox, paco, coco, cheap leftovers of the making of freebase) and algispray (that was the name of the duster), eventually one passed out in his bathtub (he used to be an old bluelighter) being on a massive dose of 1,4bdo for coming down of a 4 day binge of freon and paco, of course the ambulance and police came when he was found, he was also dealing, he;s doing time now...he had the $ and the knoweledge but decided to do the cheap shit instead, so sometimes it comes down to personal issues.
Anyway during the beggining of this year some stupid kids died huffing the shit ionside a van and now you need a script to buy it (since it was used as a muscle relaxant spray shit) , but iut's sold anyway without prescription, and glue-huiffing has been a constant problem here in the last 2 decades with the lower classes, some kids starting at 5, now many of them starting paoc at 7. It's really sad, but it's sadder when it's a well informed wealthy kid who had everything going on for him.
Back on topic, I remember I had the "wah-wahs" and turned up the music real loud, I liked monstruous sounds, also saw colors, change in movements, laughter, a soprt of telephaty, lost of control of my body, it was more remioiscient to salvia divinorium than to n20 for me, but I regret doing it more than smoking paco/oxi a couple times, freon is sorta a russian roulette, if not directly indirectly.
