The substance that gets you high in duster is called difluoroethane, and therefore it is much more dangerous than whippets, which has a smiliar effect.
Duster can be obtained at places like computer stores, Walmart, and Home Depot. Usually it's locked up, so you have to get a buyer or find a place that leaves it out in the open. When buying duster, remember to get the blue or white bottle. The purple one will probably kill you. Also, remember to NEVER inhale from the bottle upside down. You can get frostbite on your tongue, and even worse, in your lungs.
The effects of duster go something like this:
1st Hit: Numbness, feeling of happiness and euphoria
2nd Hit: More numbness, uncontrollable laughter and slurred speech
3rd Hit: Same as above but now you get dizzy, and it feels as if there is a force pulling down on your body.
Duster is really addictive. You'll tell youself you're only going to do 3 hits, but will end up doing half the can. After more than 3 hits you usually black out, but not for very long. It's usually less than a minute.
One of the good things about duster is that it does not last long. ....but the come down is a bitch.
Duster is usually 7 to 8 dollars.
