>>21088179Back when you were a flatworm and a small chinchilla like quadruped eating plants for food, the plants did a gain of function to create a molecule that would kill the herbivores trying to eat it. The way the plant shaped its attack is by working extra to create certain molecules that serve the plant in that when the herbivores eat it, it would do all sorts of damage.
https://www.youtube.com/watch?v=B-EmeQg40wEThis created a feedback loop of evolution where the animal would evolve a resistance to the plant poison, and the plant would walk in its shaped vector molecular attack to other kinds. This converged over the centuries to be Gaba inhibitors in your neurons because, paradoxically, now that your furry body is rubbing over my plant body, I might as well shed my seeds on you and make you fired up with energy to take the seeds a great distance which is the plant's best interest. This walked in from the plant trying to kill you to instead, if you're going to eat me you might as well get a big burst of energy and take my sees far away.
And so the molecule was shaped intentionally over the millions of years, by the plant and the quadriped eating it, to press your dopamine pleasure and fight or flight super-man button. The plant is telling you, incorrectly, that you have plunged your dick into sweet sexy lady, and that it's time to go a great distance and get resources for baby.
This circuit, which is why you were created, to create more of you, is a self-reward circuit, and plants learned to press it, not for your benefit, but for theirs.
And so the reason alcohol is addictive, is because doing those things that lead to more of your genetic material ending up in the gene pool is purposefully made addictive by the 97th century nanotechnology, it's why you're here in the first place asking the question, you are a survivor of survivors. So you should do whatever you did to get more of it. aka addiction.
