Truth drug

Encyclopedia : T : TR : TRU : Truth drug


A truth drug (or truth serum) is a drug used for the purposes of obtaining accurate information from an unwilling subject, most often by a police, intelligence, or military organization on a prisoner.

Drugs used for this purpose have included ethanol, scopolamine, and sodium thiopental (more commonly known as Sodium Pentothal)—all sedatives that interfere particularly with judgment and higher cognitive function. While alcohol is used for this purpose by many individuals in a more innocent sense, it is used by professionals as well. A book by a former Soviet KGB officer based in Washington, Washington Station, details the use of near-pure alcohol to verify that a Soviet agent was not compromised by US counter-intelligence services.

While fictional accounts of intelligence interrogation gives these drugs near magical abilities, information obtained by publicly-disclosed truth drugs has been shown to be highly unreliable, with subjects apparently freely mixing fact and fantasy. Much of the claimed effect relies on the belief of the subject that they cannot tell a lie while under the influence of the drug.

As of 1993 in Canada these were still used to help diagnose schizophrenic subjects, especially paranoia where the difficulty was to get the subject to talk at all. Subjects experienced with other hallucinogenic drugs reported similarity of effects of sodium amytal to that of LSD or psilocybin, but for a 20 minute period.[[Citing sources citation needed]]

Interest in their use outside intelligence services has since declined to negligible levels—though their use has been re-examined after the September 11, 2001 Terrorist Attacks. It is possible, but thought unlikely by experts in anaesthetics (the drugs most closely resembling truth drugs in common use), that intelligence services do have more effective drugs at their disposal which they have not disclosed.
