I mean yes but you also have to remember that in dune the powerful horny men are controlled by a galaxy spanning religious order of powerful horny women.

For making memes about Dune.
Who are actually being influenced by a time aware, unhorny worm man from the future
Dude. Leto II was definitely still horny as a worm man. If only for the fact he had the consciousness of every other past horny man within him.
The planet is actually made of psychedelics, not stimulants.
spice is both. it also lets you see the future, bend spacetime, and recover the memories of your ancestors. Among other things.
psychedelics also "let you" do it (and by that i mean make you feel like you can)
It only lets you bend spacetime in the David Lynch movie.
It's explicitly described as allowing spacetime bending in the books, maybe Villeneuve will talk more about it in the nexr movies
If you watch really closely in Dune P1, you can see another planet (presumably Selusa Secundus) through the center of the navigator ship. I don't know how it functions mechanically in his version, if they're navigating wormholes somehow or controlling them, but they have some form of wormhole mechanism shown in the series.

Spacefolder ships use the Holtzman effect to bend spacetime. Computers were used to find safe routes before the Butlerian Jihad. Without computers, guild navigators use their prescience to find safe routes. Spice doesn’t allow spacetime bending, just navigating through bent spacetime without a high fatality rate from flying into stars.
Spice is much more than a psychedelic or a stimulant, I would say it's more like if an Adderall pill and a microdosed LSD stamp had a kid
