The characteristic of GHB that disqualifies it as a hallucinogen is that it doesn't alter perception. Hallucinogens are substances that lead to significant changes in sensory perception, thought processes, and emotional experiences. They typically provoke vivid visual or auditory hallucinations and distort the user's sense of reality.

GHB, on the other hand, is primarily classified as a depressant. While it can lead to alterations in consciousness, the type of alteration it causes is more akin to sedation or the potential for blackouts rather than the enriched sensory experiences characteristic of hallucinogens. GHB use can result in depressant effects such as drowsiness or lethargy, rather than the perceptual distortions associated with hallucinogenic substances. Thus, its lack of perceptual alteration is a key reason it does not fit the hallucinogen category in the way that substances like LSD or psilocybin do.

Other effects mentioned, such as causing blackout states, inducing euphoria, or having stimulant properties, do not pertain to the core trait of perceptual alteration that defines hallucinogens.
