Vaping "exotic" stuff.

So most of you know about vaping and so called Vape Gods". Well I've heard about people smoking Red Bull and alcohol. Now I have a question, why would ANYONE smoke alcohol?! It just sounds extremely dangerous! Sure it MIGHT affect you faster, but to me it just sounds like it would kill you really fast! Now smoking Red Bull... that just sounds nasty. Wouldn't it taste burnt? How can a burnt energy drink taste good? And considering all the chemicals they put in these energy drinks, who knows what type of effect it would have on you're lungs.
