How does addiction work?

Andrew Huberman AI:

Addiction works through a core set of processes in our brain, regardless of whether it's to a substance or a behavior like gambling, sex, or even work. As Dr. Anna Lembke and I discussed, nature didn't evolve different mechanisms for different types of addiction. Instead, there's a generalizability in our brain circuitry. This means that once you've been severely addicted to a substance or behavior, it makes you more vulnerable to addiction to any substance or behavior. This is due to the pleasure-pain balance in our brain, which can be triggered by various things, leading to the same underlying addictive response.
