That's a strange technicality to get hung up on. "Hallucinogens" are perhaps a broad class of psychotropic drugs, of which dissociative anesthetics are a part. A laptop is still a computer.
From Wikipedia's definition:
"A hallucinogen is a psychoactive agent that often or ordinarily causes
hallucinations, perceptual anomalies, and other substantial subjective
changes in thought, emotion, and consciousness that are not typically
experienced to such degrees with other drug classifications."
The traditional dissociatives definitely would classify as changing your thoughts and consciousness.
This is extremely broad, in that case cigarettes are hallucinogens. Nicotine is a psychoactive substance, it absolutely alters though patterns and consciousness.
>often or ordinarily causes hallucinations, perceptual anomalies, and other substantial subjective changes in thought, emotion, and consciousness that are not typically experienced to such degrees with other drug classifications
I think you left out an important part of the stated definition, this also says "and" rather than "or". I think that "dissociative" is a more accurate classification the the compounds' primary effects seen at the majority of doses.
I mention in another comment in this thread why I think it is a poor classification, please refer to that message for my argument.
