Why Not Go After "Big Alcohol"?

There have been lots of lawsuits in recent years against the tobacco industry, the gun industry and now the food industry. Why hasn't anyone gone after the alcohol industry?

Not that I think anyone should go after them but people choose to drink. Furthermore, alcohol is designed to intoxicate and going by court judgments of recent years, that ought to be enough to set them up for massive liability damages in everything from drunk driving deaths to accidental pregnancy. Refer to the song "Alcohol" by Brad Paisley for other side effects of booze.

So why does that industry seem to be immune? Is it because Prohibition was so thoroughly discredited that no one dares go after them? Were they assigned some sort of Congressional immunity some time in the past?

I'm open to your theories, let me know what you think.
