Narco-analysis test is the tool of forensics to catch the culprits and trace the criminals and decipher their modus operandi by administering hypnotics or similar drugs (popularly known as Truth Serum) into the suspects. In the Narco-analysis Test, the subject’s imagination is neutralized by making him semiconscious. In this state, It becomes difficult for him to lie and his answers would be restricted to facts he is already aware of. In India the technique became more popular in June 2000, three months after the burning of a train coach by the mob at Godhra in Gujarat and leading to massacre of Muslims. Seven persons accused of torching the train were interrogated and subjected to Narco-analysis who revealed vital clues. Since then, it is used intermittently on the suspects of crimes, enough to cause worry that it might become a routine technique of Police Investigation before it is duly accepted by law and judiciary as safe practice.
