The Book of Rack the Healer by Zach Hughes was pretty wild.
It’s ‘New wave’ sci-fi from the 1970’s, and revolves around these mutated humans in a deeply poisonous and radioactive world where it’s forbidden to dig into the earth.
The humans have evolved a carapice and internal air sacks that they fill to hold their breath before leaving their safe organic dome homes that change color depending on their mood. Some of the domes have women in them that don’t seem capable of complex thought, and live purely through sensory input, are telepathic, and are basically constantly edging themselves all day.
It’s a drug fueled fever dream, for sure.
That sounds a bit like “The Prince in Waiting” by John Christopher (more famous for “The Tripods”), it’s a trilogy also set in the distant future after a nuclear war, where all machines have been outlawed and humans exist alongside dwarfs and mutants. Over the course of the trilogy, the protagonists (living in fairly alright areas) venture deeper into more and more radiated areas and encounter grotesque stuff.
I found my next read. Copy ordered.
I read Mother Load by Zach Huges decades ago. Not as strange as the one you describe but I still remember it.
