Huffing, about as good of an idea as plastic flamethrowers filled with fuel and air.... I'm not sure which is more likely to kill you. I also knew someone who tried huffing butane then scotch-guard. He didn't die, however he ended up in a coma for a few weeks. They even aired the story on Rescue 911 back in 1992 around christmas I think it was. He ended up with some serious brain damage. not in the stupid sort of way, but the insane sort of way. Last I had heard of him he had raped his own sister, and was incarcerated. I'm not entirely certain if that was in a jail or mental institution. He went to high school with me, and before he went off the deep end we were sort of friends.
