On one hand, I can't agree with the government leaning on MillerCoors and Anheuser-Busch/InBev till they pulled the plug on their alcoholic energy drinks. So perhaps they were marketing them to underage kids. Stuff gets marketed to kids too young to be partaking of it all the time and that's what parents are supposed to be for. I know comments like that catch me a lot of flak, but it's the truth. We can't kid-proof the world. Sorry.
And supposedly there were health risks associated from mixing alcohol and caffeine. I frankly haven't looked into this and can't comment, but I will say that there are health concerns with stimulants and health concerns with depressants--and if you mix the two, I could probably believe you get some combo that's the worst of both worlds. But if there are proven risks, document on the can. I doubt they'd do any good--see Denis Leary's routine about warnings on cigarettes for reference--but we can't (and shouldn't) protect people who are (mostly) in their right minds from willfully and consensually damaging themselves. Sorry about that too.
But setting all that aside, I have never understood the appeal of alcoholic energy drinks. I mean, seriously: make up your damn mind. Do you want to be up? Or be down? Do you want stimulants? Or do you want depressants? If you take both at the same time don't you just wind up back where you started, except for having consumed a crapload of sugar, thumped your liver a good one and freed your wallet of several bucks? So I can't shed a tear for their passing. Is anybody else sorry to see them go?
