Does herion a hallucinogen?

Hallucinogen is a general term for drugs that cause one to have hallucinations or, more broadly, those that drastically alter one's perception (which is technically is not considered hallucination)....

PCP is sometimes considered an hallucinogen because it has some of the same effects. However, it does not fit easily into any one drug
