What Are the REAL Effects of Inhaling Chloroform?

[HeyHomie]

I've seen this device used in movies from time to time: somebody soaks a cloth in chloroform, holds it over a person's mouth and nose, and the person is instantly unconscious. This technique was generally used to facilitate anesthesia or to facilitate kidnapping.

What really happens when someone inhales chloroform? Can it kill you? How long do its effects last? How do you revive somebody rendered unconscious by it?

TIA
