Question

Can Phenobarbital be used as a truth serum? How?

Answer 1

I think secobarbital was the original truth serum used in WW II etc. Its not so much truth inducing as it depresses inhibitory signalling in the brain: its really the effect people get when waking up from an aneasthetic and the blurt out personal stuff. I don't think its very sophisticated though as a truth serum

Answer 2

no....it's used for seizures

Answer 3

It does come in injectable form. The reason other barbituates have been used as "truth serums" and phenobarbital isn't is simply that the others are shorter-acting and therefore more controllable.
