1. Sodium Amytal
Sodium Amytal lowers inhibitions, giving the user mental clarity and the impulse to talk while offering the interviewer an unobstructed view of the subjects psyche. World War II was its debut, when interviewers begin using it to work with soldiers whom refused to talk on account of psychological trauma. Sodium Amytal, a barbiturate, would force the soldier to relive their wartime experiences and talk about them with the interviewer.
2. Mescaline
The peyote cactus can be processed into Mescaline, a hallucinogen with effects similar to those of LSD. The Nazis were first to use it during their mind control experiments, and later on the U.S. Navy gave it a go as a sort of truth serum. Both experiments failed. The Navy found that information gained from a psychotic (even when drug-induced) is unreliable. The Nazis found it impossible to control minds, even with the help of Mescaline.
3. Scopolamine
Scopolamine is most commonly known as the “truth serum”, having a remarkable track record of making criminals sing like canaries. However, not too many know the dirtier underbelly of scopolamine. It’s also a “zombie drug”, able to rob users of all free will, leaving them helpless to the wishes of the inducer. That is, if the miniscule amount needed doesn’t kill the victim beforehand.
