How Long Does It Take To Knock Out A Person Using Chloroform? The effects of chloroform exposure on a human increase proportionally with its dosage. If consumed in mild doses, it can daze or knock a subject out, whereas when consumed in high concentrations, it has the potential to be fatal. However, its golden age was brief, as it was gradually replaced by ether (much safer than chloroform, with practically no side effects). These problems include organ damage and heartbeat irregularities. There’s a good reason chloroform is no longer used as an anesthetic today; it’s a challenging task to determine the right dosage that would render a person unconscious without impinging other vital nerve functions. Chloroform begins to act within a few seconds of inhalation, provided the method of delivery has sufficient concentration and the user takes a deep enough breath. Along with chloroform, the victim might faint because of suffocation, as placing a rag over the nose and mouth would not allow the victim to breathe.
