The application of forensics is developing together with technological advances. It aids in locating both crimes as well as criminals in a criminal investigation. The constant advancement of crime scene investigation over time was aided by the employment of technologies. Narco analysis, as a scientific tool of crime detection, has aided investigators in investigating crimes and also serves a crucial role in the criminal justice system. In this sense, the investigators rely on narco analysis to acquire evidence, and the legal system acknowledges these without weighing several legal and moral concerns. Seeing the present situation anywhere criminals are using modern technology to execute criminalities, narco analysis has become imperative for the detection of crime. Basic human rights are being ignored due to the extensive use of the narcoanalysis technique on the suspects of the crime. Today, the root of the problematic situation is to create stability amongst the privileges of the accused of the crime and the usage of scientific deception tactics while keeping social and individual interests in mind. This practice appeared to give psychological aid in solving cases concerning dreadful crimes. It has been alleged that the legal system took an integrated approach to the employment of this technique and established a concept of restricted usage, indicating that the process and implementation in every criminal case should not be neglected. The reliability of the narco analysis has not been determined by the courts still in India. This paper gives insights into the usage of narco analysis by the investigating authorities and the concerns allied with this impugned technique. However, it is suggested that narco analysis should be assimilated into the legal mainstream with due care and circumspection.
