yeah be careful with it though. when I was a kid (like 16-18) a fireman caught me and a friend takin' puffs from one of those and swiped it from us, saying he ends up responding to calls on a regular basis from people who over do it and end up having cardiac issues. Also around that time the media was also sensationalizing the deaths of a couple of models who used the stuff as well. Of course knowing the media, they probably 'overlooked' things like coke/meth/heroine habits, the wasted skank look was really popular in the 90's...
