The Biology of Desire: Why Addiction is Not a Disease
Share
In The Biology of Desire, neuroscientist Marc Lewis challenges the traditional view of addiction as a disease. Instead, he argues that addiction is a learned behavior based on changes in the brain’s wiring due to repeated substance use. The book offers a scientific yet hopeful perspective, showing that addiction can be unlearned through neuroplasticity—the brain’s ability to change and adapt.
At Today’s Sober Women, we love that Lewis offers a fresh take on recovery, one that focuses on personal agency and brain change. This book shows that healing is possible by rewiring the brain and breaking free from destructive patterns.
Key Principle #1: Addiction is Not a Disease
Lewis argues that addiction is not a disease but a learned behavior. Understanding how the brain adapts to substance use helps us see that addiction can be overcome by unlearning those behaviors.
Key Principle #2: Neuroplasticity
The book emphasizes neuroplasticity, the brain’s ability to change and create new, healthier patterns, offering hope for recovery through conscious efforts to rewire the brain.
Key Principle #3: The Power of Habit
Lewis delves into the habit loops that form in addiction, helping readers understand the mechanisms behind cravings and how to break free from them.
Key Principle #4: Personal Agency in Recovery
One of the most empowering aspects of this book is its focus on personal agency—the idea that we are not powerless over addiction, and that we can actively reshape our brains to support recovery.
Key Takeaway: Addiction is a learned behavior, not a permanent condition. Today, reflect on how you can actively work to change the patterns that keep you stuck and embrace the power of neuroplasticity.
