The Biology of Dopamine: Why We Can't Stop What Isn't Good for Us

You know it's not good for you. You do it anyway. Then you ask yourself why. Late-night scrolling when you promised you'd sleep. Sugar after dinner when you said you'd stop. The fight you picked that you didn't need to pick. We call it lack of willpower. But willpower isn't the problem. This is the biology behind the main episode this week with addiction policy expert Dr. Kevin Sabet. He shared what we've been getting wrong about marijuana and addiction. Now I'm taking you deeper into what's actually happening in your brain when you can't stop doing what you know is harming you. In this episode you'll hear more about: (01:00) Why "why am I doing this to myself" is a dopamine question. (02:30) The truth about dopamine — it's not just high or low. It's both. (03:00) How drama and interpersonal chaos become dopamine sources. (04:30) Why the more you push the lever, the less dopamine you get. (05:00) Dopamine isn't about pleasure. It's about remembering what's important. (07:00) How early attachment wires dopamine to connection — or to danger. (09:00) The definition of addiction: going somewhere other than safe human connection to feel okay. (10:30) The three biochemical imbalances common in addictive patterns. (11:00) How brain inflammation lowers dopamine and raises glutamate — the double whammy. (12:30) Why bribes actually work for dopamine-driven behaviors. The craving isn't a character flaw. It's a signal. When dopamine is low at baseline, your nervous system will find ways to get it. The question is whether we repair the biology or white-knuckle through life.
