|The 'truth' might set us free|
MethodIn a clinical settting narocoanalysis and narcotherapy are conducted in a treatment room. The patient lies quietly with an iv line in place. While the psychiatrist recapitulates the patients history in a low monotone a nursing assistant injects thiopentone sodium to terse instructions of “push 50” or “25 slow”. Thiopentone sodium is no rare drug. It is used everyday to induce general anaesthesia. At lower doses in willing patients it produces a state of relaxation. You have to be careful the patient does not doze off or start slurring in speech. At the start of the narcoanalysis attention has to be paid to the patient's posture and eye movement. Horizontal eye movements indicate a state of sufficient relaxation to proceed with the deeper probing interview. Subsequent aliquots are adjusted with the aim of maintaining this state during the rest of the interview.
- The aim of narcoanalysis is to produce an abreaction in hysteria and other disorders in which there is an element of dissociation. During abreaction the patient recalls traumatic experiences and, by talking about them, discharges associated disturbing emotions. Abreaction facilitates subsequent and sometimes dramatic recovery (Breuer & Freud 1957). However, there are only anecdotal - though fascinating and highly readable - reports for the effectiveness of narcotherapy (Miller 1954, Denson 2009). The theory is based on the unconscious suppression of emotion through use of psychological defense mechanisms. It may not apply when suppression is done consciously as in most forensic cases .
- Narcotherapy is effective in relieving catatonic mutism (McCall et al 1992).
- Narcoanalysis was never considered as a method to get at the ‘truth’. It was just the patients perception of whatever he or she believed at that time. A similiar process occurs every night in the bar when a garrulous, intoxicated person talks about whatever is bothering him or her.
- A person can consciously lie during the procedure and get away with it.
- At times it is difficult to separate actual events from fantasy.
- You can even plant an idea into a persons mind through leading questions and later they would have no doubt it was their own.
Present statusA PubMed search using the MeSH term ‘narcotherapy’ gives just two articles in the last ten years. There are no randomised control studies - the scientific standard - to demonstrate the reproducibility of results obtained by narcoanalysis for information gathering, abreaction, or lie detection. Randomised control studies would give us an idea of the procedures sensitivity - the number of actual cases that would not be detected; and its specificity - the number of innocents who would be implicated. Presently all we have to go on are anecdotal reports of narcoanalysis practitioners . Not enough evidence to rely on narcoanalysis for deciding the fate of an unwilling subject. Not even for spies caught in Pune. Even the judiciary is sceptical of narcoanalysis..
