Morphology

truth + drug

The meaning 'a drug that induces people to talk freely or tell the truth' is directly and predictably built from combining 'truth' (truthfulness) with 'drug' (a chemical substance). This noun+noun compositional pattern (a drug for truth) is straightforward and common across languages, so a B1 learner who knows both constituents would readily infer the intended meaning.

Etymology

Truth drug comes from the simple image that a drug might make someone lose their fear and say the truth. So the term means a drug believed to make someone 'tell the truth', but that does not always work.
