computer duster?

anyone ever do computer duster i heard it was great for about thirty seconds and i also heard it could kill you because it freezes your lungs. tell me good things and bad things about it

ive never tryed it myself
but ive seen peeps do it...

it makes ur voice like really low
and it sounds weird...

i would never do it though
if ya ask me its stupid...

if ya do it ur a idiot dude..
sorry... get mad if ya want
but...

peace

wtf is it?? or is it like stuff you clean your pc out??or is it like gas you put in lighters?? lol as that stuff makes your voice really low....hmmmm never heard of such a thing

yeah i was scared when i first tried it just hold it upright and dont do it alot or hold it in and you wont freeze your lungs i think but i just sprayed it in front of my lips and inhaled it and i talked really low and then thought it was cool and did it for like 10 min. so then i put it down and stood up and almost passed out you feel like drunk and EXTREMELY lightheaded. its a shitty feeluing but sorta cool if you like it i guess but i say dont do it or just try it once cause the high lasts like 20 sec. and its hardly a high

ive done befor, its not worth the time or the effort, think about the affect when you sniff gas, its exactly yhe same way, for the amount of money the stuff costs a 30 second high isnt worth it

Isnt the stuff that is in those duster things pretty much oxygen?

i just tried duster for my first time and it is crazy if you do it right if feels like a fucking acid trip for thirty seconds though, i was looking at the wall at my friends house and a vortex just opened up i swear to god it was crazy, i held it in my mouth for about a minute and that is a really long time to do it so that is why i was fucked up that much, oh and i also heard the pac man music in my head wow shits insane
