Is alcohol a stimulant that affects judgement drug that affects judgement hallucinogen that affects judgem?

It's a depressant: The first thing alcohol depresses are our frontal lobes, where our inhibitions live, so initially and in low doses alcohol "disinhibits" making people more likely to socialize, dance or whatever. However, in higher doses its effects are depressant, making people sleepy and ultimately can cause coma and death. It is neither a stimulant nor a hallucinogen in most people.
