It “only” tests for GHB. Is it even reliable then?

Xantus is criticized in a small number of reports for “only” testing for one substance. Theoretically a variety of substances are used as knockout drops to spike drinks. However, the majority of these potential substances are not suitable in practice, as they can be detected by the “victim” or cause “undesired” reactions. From the perpetrator’s point of view, GHB is the “ideal” and best-known knockout drop, as it cannot be detected. Often, symptoms similar to those of alcohol appear because those under the effects of GHB can feel as if they were heavily intoxicated.
