a drink must contain water otherwise you're not drinking but eating or taking substances.
Not true. I've got a bottle of IPA that's 99.953% pure. Bought it at Fry's.
Buy.com, among other places, sells it, too:

And it is possible to produce 100% pure, but rarely seen in consumer sales....typically reserved for scientific circles for specimen preservation.
everclear
McDonald's shakes?
This is probably as close as you'll get.
the title of the thread should be:
are there any "SAFE" drinks that don't contain water?
btw, milk is water based, but with complex ingredients, making it more unique, but not completely without water.
I had some 100% EtOH for a while. It smells like candy. Never drank it though. Oh, and we had pure deionized water too. Apparently that tastes like nothing. Coulda made some kickass vodka. Didn't though.
OP: You can get close enough if all you want is a non water-based drink, but none of them are very good.
