Re: Alcohol in base?! Sounds dangerous to me!
From a medical standpoint, its not how you got the alcohol in your blood that's going to make a difference, its how much. There is no greater danger in inhaling alcohol than there is in smoking alcohol. True, the alcohol will get to your brain faster, but that doesn't have some greater negative affect than the alcohol that reaches your brain after drinking it. One just happens to be a faster way of getting drunk. I can't think if any pathological reason for why inhaling alcohol vapor would be dangerous for your lungs.
I personally stick to water, but I'm a little bit of a hookah purist. To each their own.
