[00:00:00]The intellectual version of that is for anyone who wants to look it up is the work of two researchers Kent Barage and Terry Robinson at the University of Michigan. Their model is called incentive sensitization theory. They proved in animals and in humans that wanting and liking are two different systems in the brain.

[00:00:27]Wanting is the dopamine. Liking is something else entirely. A much smaller and quieter system using natural opioids.

[00:00:39]And here is the punchline. Addiction makes you want more while liking less.

[00:00:47]That's the trap. The craving gets louder while the satisfaction gets quieter. The hunger grows while the meal shrinks.

[00:00:59]That is true of cocaine. That is true of heroin. That is true of slot machines.

[00:01:05]That is true of Instagram. That is true of a man who can't stop checking his stock app at 3 in the morning. Same circuit, same trap, different costume.

[00:01:19]The director of the National Institute of Drug Abuse, Dr. Nora Vocal has been publishing peer-reviewed neuroscience for over 20 years showing this. The brain on food, the brain on cocaine, the brain on gambling. These PET scans look more similar than they look different. This is not a fringe view. This is the head of NIDA, the official position of the United States government's drug research arm.
