The U.S. Food and Drug Administration alerts consumers and retailers of the potential for serious injury from eating, drinking, or handling food products prepared by adding liquid nitrogen at the point of sale, immediately before consumption.
These products are often marketed under the names "Dragon's Breath," "Heaven's Breath," "nitro puff" and other similar names.
[...] Foods and drinks prepared by adding liquid nitrogen immediately before consumption may be sold in malls, food courts, kiosks, state or local fairs, and other food retail locations. These products may include liquid nitrogen-infused colorful cereal or cheese puffs that emit a misty or smoke-like vapor. Similarly, alcoholic and non-alcoholic drinks prepared with liquid nitrogen emit a fog.
The FDA has become aware of severe -- and in some cases, life-threatening -- injuries, such as damage to skin and internal organs caused by liquid nitrogen still present in the food or drink. There has also been a report of difficulty breathing after inhaling the vapor released by liquid nitrogen when added immediately before consumption. Injuries have occurred from handling or eating products prepared by adding liquid nitrogen immediately before consumption, even after the liquid nitrogen has fully evaporated due to the extremely low temperature of the food.

I've seen the chefs on some cooking shows use Liquid Nitrogen to do some things. I never thought about possible problems for the person actually consuming the thing. Not that I've ever been to a place that offered that as an option, but that's definitely something to chew on. I'll just put that on the same list as Puffer Fish and live octopus; things not to try.

Chefs and the alcohol industry are just doing this stuff because it looks cool, and that flashy looking drink generates interest. The unfortunate thing is liquid nitrogen's normal boiling point is so frickin cold that it tends to film boil at room temperature. That film boiling often sets up a Leidenfrost effect https://en.wikipedia.org/wiki/Leidenfrost_effect, [wikipedia.org] and the resulting vapor blanketing causes a liquid that boils at -320 F (-196 C) stick around way longer than a lay person would expect. I didn't realize this was a trend, but it sounds like quite a dangerous one. Somebody is just bound to get some cold burns or cracked teeth ingesting this stuff. The volumes probably aren't large enough to result in asphyxiation, but nitrogen is quite sneakily good at that too. Then there's the whole >700x volume expansion from boiling liquid to vapor at body temperature. But hey, I sure bet those foggy drinks look awesome.
