> similar cultural affection to hallucinogens, pot or even pure methamphetamines would be less harmful
As someone who lived in a region with heavy meth use, I can tell you that I would much rather deal with drunk people than meth heads. Also, your sentences before this one don't make any sense, "alcohol as a solvent is very similar to many inhalants as a drug" what does that even mean?
> Imagine a sci-fi story where you encounter human settlement that consumes solvent
In your sci-fi story you forgot to mention that this solvent people drink also tastes very good, produces a sense of euphoria, lowers social inhibitions and reduces stress.
> Women wearing high-heels is be another very odd cultural artifact
No, same as your sci-fi story it would not. The reasons behind high heels are sad and ridiculous, but rather obvious. High heels make you look taller, give more definition to your legs and make you look a bit helpless and fragile. All of this is in tune with making females look more attractive in a male dominated society.
