World’s First Narco Test: Narco test is an interesting forensic technique. It is used during criminal investigation. Actually, in this a drug, which is usually sodium pentothal, is given to the person to take him to a state of semi-consciousness or hypnosis. After going into this state, all the hesitations of the person are reduced and it is believed that his ability to lie is also suppressed. This technique is used to obtain true information from the person. Today we will know when the narco test was first done and how criminals confess their crimes by using it.
When did the narco test start?
This test was first performed in 1922 in the United States by Dr. Robert House, an gynecologist from Texas. The doctor had used a drug called Scopolamine on two prisoners to see if this drug could force them to tell the truth.
How does this test work?
Narco test is based on some medicines. These are usually called truth serums. These medicines affect the normal functioning of the brain. Substances like sodium pentothal or sodium amytal reduce self-control and the power of imagination of the human mind. It is because of this that a person is not able to fabricate a false story.
what is the whole process
First of all, the medicine is delivered to the person’s body through injection. The quantity of medicine depends on the age, gender, health and physical condition of the person. This test is completed by a team of experts. This team includes an anesthesiologist, psychiatrist, clinical or forensic psychologist, and medical staff to monitor the person’s condition.
When the person reaches a complete trance-like state, the doctor starts asking him questions. Video recording of this entire process is done. This is because during this entire process the person can give some information which can come out spontaneously or without any filter and which can be considered as a clue.
Accuracy and limitations
Despite scientific validation, narco test is not completely reliable. Under the influence of medicine, a person can mix truth with imagination. This is the reason why statements given during narco test are not considered legally or scientifically conclusive. At the most, those things are used as investigative clues for further investigation.
Legal and constitutional aspects in India
No person can be forced to undergo narco test in India. Doing so is a violation of Article 20 (3) of the Indian Constitution. At the same time, this test can be done only with the person’s own will and informed consent. The results of this test are not accepted as direct evidence in court. However, if any new evidence or material is found as a result of the information obtained during the narco test, then it is accepted under Section 27 of the Indian Evidence Act 1872.
