Nicotine: The Molecule That Hacks Your Brain

How a plant molecule reaches your brain in seconds — and why it's so hard to quit.

About

In 1994, seven tobacco company CEOs swore before Congress that nicotine isn't addictive. Their own internal documents, three decades earlier, said the opposite.

This audiobook explains exactly what happens inside the brain when nicotine touches it: how it mimics a natural neurotransmitter, how it hijacks the reward circuit, and why the brain itself "rebuilds" around it until it simply needs the molecule to function normally.

It isn't only the story of an addiction that kills more than eight million people a year. It's also the story of a molecule with real, documented positive effects — on attention, on memory, even in clinical trials for Alzheimer's — that the tobacco industry learned to exploit scientifically, artificially boosting the speed and intensity with which it reaches the brain.
