In 1865, The Lancet, the medical journal, called upon any person, criminal or not, to prove that waving a chloroform drenched handkerchief was enough to knock someone out. No one has to date come forward with an answer.
While the right dose of chloroform soaked in a rag can definitely render you unconscious (the Lancet articles cites 5 minutes and persistance should knock someone out, but no experimental evidence was provided), it would take much longer than what they show in movies: you wouldn’t drop unconscious just by taking a whiff.
What Does Chloroform Smell Like?
Chloroform is a sweet-smelling liquid, similar to ether, along with a slightly sweet taste. Some people compare the smell to the smell of disinfectants, similar to the smell that is perceived in hospitals and medical facilities. We interviewed a number of chemists working in chemical laboratories who explained that the chloroform smell vaguely resembles the smell of acetone, an organic compound.
Lots of chloroform questions here.
Hopefully this will answer some:
