Why Does Fentanyl Feel So Good? (The Neuroscience of a 2mg Trap)

Why is the human brain wired to feel a wave of pure bliss from a synthetic molecule the size of two grains of salt — and why does that exact mechanism turn into the deadliest drug trap in modern history? In this 2D animated science documentary, we trace the evolutionary origin of the mu-opioid receptor, how opioids silence GABA inhibitory neurons to trigger a dopamine tsunami, why tolerance and withdrawal rewire your baseline for happiness, and why illicit fentanyl conquered the global drug supply. ⏱️ CHAPTERS / TIMESTAMPS: 00:00 - 01.
