well, The term Narco Analysis was coined by Horseley. Narco analysis first reached the mainstream in 1922, when Robert House, a Texas obstetrician used the drug scopolamine on two prisoners. Since then narco testing has become largely discredited in most democratic states, including the United States and Britain. There is a vast body of literature calling into question its ability to yield legal truth. Additionally, narcoanalysis has serious legal and ethical implications.
A person is able to lie by using his imagination. In the Narco Analysis Test, the subject's inhibitions are lowered by interfering with his nervous system at the molecular level. In this state, it becomes difficult though not impossible for him to lie. In such sleep-like state efforts are made to obtain "probative truth" about the crime. Experts inject a subject with hypnotics like Sodium Pentothal or Sodium Amytal under the controlled circumstances of the laboratory. The dose is dependent on the person's sex, age, health and physical condition. The subject which is put in a state of hypnotism is not in a position to speak up on his own but can answer specific but simple questions after giving some suggestions. This type of test is not always admissible in the law courts. It states that subjects under a semi-conscious state do not have the mind set to properly answer any questions, while some other courts openly accept them as evidence. Studies have shown that it is possible to lie under narcoanalysis and its reliability as an investigative tool is questioned in most countries. A few democratic countries, India most notably, still continue to use narcoanalysis. This has come under increasing criticism from the public and the media in that country. Narcoanalysis is not openly permitted for investigative purposes in most developed and/or democratic countries. but the result of such test can not be used as evidence in the court of law since it violates fundamental right against self-incrimination (Article 20(3) of the constitution of India).
