Well, that didn't last long. Phusion, the maker of Four Loko, announced late yesterday that they're only producing non-caffeinated (and -guaranad and -taurined) versions of their beverages from now on:

We have repeatedly contended — and still believe, as do many people throughout the country — that the combination of alcohol and caffeine is safe. If it were unsafe, popular drinks like rum and colas or Irish coffees that have been consumed safely and responsibly for years would face the same scrutiny that our products have recently faced.

In addition, if our products were unsafe, we would not have expected the federal agency responsible for approving alcoholic beverage formulas — the Tobacco Tax and Trade Bureau (TTB) — to have approved them. Yet, all of our product formulas and packaging were reviewed and approved by the TTB before being offered to consumers.

We are taking this step after trying — unsuccessfully — to navigate a difficult and politically-charged regulatory environment at both the state and federal levels.

Enjoy the existing supply while it lasts, possibly while listening to Baby T's "Four Loko Sippin'":
