Therefore, it is not a plausible scenario that the villain holds a cloth soaked in chloroform while waiting for the victim to appear, since the chloroform in the cloth would lose its effectiveness by the time it is actually pressed against the victims nose. Chloroform, if inhaled in very small doses, can keep a person unconscious from 20 minutes to 2 hours or even more, depending on how concentrated the dose is. } The rise of gas anaesthesia using nitrous oxide, improved equipment for administering anaesthetics and the discovery of hexobarbital in 1932 led to the gradual decline of chloroform narcosis. Animal testing may also be used to identify health effects such as cancer or birth defects. It may enter water and soil from spills and by leaks from storage and waste sites.
