Yes there are redbull and vodkas, but think about it; a redbull is about equal to one cup of decently strong coffee, and the vodka portion of the drink is DEF not equal to 6 odd beers. So to compare the portion of fourloko to a jagerbomb or vodka and redbull just isn't equivalent. It's the fact of young immature kids getting ahold of these dirt cheap beverages, having a reaction/blacking out and aspirating that's the scary thing.
Rwik, you're from Boston, I don't know if you're a student or work around here, but around Northeastern, it's everywhere, the campus is freaking out about these things, and I know a lot of people who have horrible, terrible stories to tell about what happens when they are consumed- they aren't just your everyday vodka and redbull...they're about six and a half of those, and it comes in a pop-top that lets you chug it down like an energy drink.
