When humans were young, long before phones, v**es, and alcohol, there was dopamine, the chemical that helped humans survive. When our ancestors found food, warmth, or safety, dopamine rewarded them. It kept our species alive. Now we live in a world where everything is instant; food is everywhere, and we’re always connected.
Our brains have been built for survival, and we are still chasing rewards (just bigger and faster ones). That’s why things like social media, ni****ne, and alcohol can feel so powerful; they spike dopamine way higher than just surviving
Over time, those constant dopamine rushes can change the brain. Ni****ne, for example, bonds to dopamine receptors and increases release. With repeated use, the brain adapts, creating more dopamine receptors to then excite later, which can make normal activities feel less exciting and create cravings instead. Addiction isn’t a personal flaw(it’s about 55% genetic); it’s what happens when a survival system meets a modern world. Like Keith Humphreys says in an article titled ”Why our brains are wired for addiction: What the science says,” published by Stanford Medicine, “We have an old brain in a new environment.”
