Pro's and Con's Pro: You get just as drunk and the same drunk as you do from drinking. It's a great party trick, and the more you get into your setup, the better the results. I personally don't get sick. I've heard people discuss how it makes you absorb alcohol through alvioli (sp?) in the lungs so it skips the liver. Con: You gotta do it a lot if your container can't hold a lot of pressure. You'll get addicted to trying to make a better machine, lol. A 2L only can vaporize a little alcohol at a time so you can breathe in about 20 times and get kinda screwed up. If you hang out with some nuts from the 155 Combat Engineers, they can make you something fierce that will slam 3 shots of everclear into your lungs in a breath. Holy shitballs, hold onto your hat.
