TRANSCRIPT:

DR. ANDREW HUBERMAN: Welcome to the Huberman Lab Podcast, where we discuss science and science-based tools for everyday life. I’m Andrew Huberman, and I’m a professor of neurobiology and ophthalmology at Stanford School of Medicine. Today, I have the pleasure of introducing Dr. Anna Lembke.

Dr. Lembke is a psychiatrist and the chief of the Addiction Medicine Dual Diagnosis Clinic at Stanford University School of Medicine. She’s a psychiatrist who treats patients struggling with addiction. She has successfully treated patients dealing with drug addiction, alcohol addiction, and behavioral addictions, such as gambling and sex addiction, as well as other types of addiction.

In fact, during our discussion, I learned that there are a huge range of behaviors and substances to which people can become addicted to, and that there is a common biological underpinning of all those addictions. I also learned that there’s a common path to the treatment and recovery from essentially all addictions. Dr. Lembke explained that to me and explained how to think about and conceptualize our own addictions, as well as the addictions of other people who are struggling to get treatment, move through treatment, and stay sober from their addictions.

In addition to treating patients, Dr. Lembke is an author and was featured in the 2020 Netflix documentary, The Social Dilemma. I’m excited to tell you that she has a new book coming out called Dopamine Nation, Finding Balance in the Age of Indulgence. The book comes out August 24th and is an absolutely fascinating read into addiction and ways to treat various types of addiction.

I’ve read the book cover to cover, and all I’ll tell you is that at the very first chapter and throughout, you are going to be absolutely blown away. The stories about her patients are extremely engaging. It brings forward the real struggle of addiction and the incredible I think it’s fair to say heroic battles that people fight in order to get through addictions of various kinds. And all of that is woven through with story, with science, and ways that make it very accessible to anyone, whether or not you have a science background or not.

I can’t recommend it highly enough. So again, the book is Dopamine Nation, Finding Balance in the Age of Indulgence. It comes out August 24th of this year, 2021, and you can pre-order that book by going to Amazon. We will provide a link to that in the show caption.

And now for my discussion with Dr. Anna Lembke.

What is Dopamine?

DR. ANDREW HUBERMAN: All right. Great to have you here.

DR. ANNA LEMBKE: Thank you for having me. I’m excited to be here.

DR. ANDREW HUBERMAN: Yeah, I have a lot of questions for you. I and many listeners of this podcast are obsessed with dopamine. And what is dopamine? How does it work? We all hear that dopamine is this molecule associated with pleasure. I think the term dopamine hits like I’m getting a dopamine hit from this from Instagram or from likes or from praise or from whatever is now commonly heard. What is dopamine? And what are maybe some things about dopamine that most people don’t know and probably that I don’t know either.

DR. ANNA LEMBKE: So dopamine is a neurotransmitter. And neurotransmitters are those molecules that bridge the gap between two neurons. So they essentially allow one neuron, the presynaptic neuron, to communicate with the postsynaptic neuron. Dopamine is intimately associated with the experience of reward, but also with movement, which I think is really interesting because movement and reward are linked, right? If you think about, you know, early humans, you had to move in order to go seek out the water or the meat or whatever it was. And even in the most primitive organisms, dopamine is released when food is sensed in the environment, for example, C. elegans, a very primitive worm.

So dopamine is this really powerful, important molecule in the brain that helps us experience pleasure. It’s not the only neurotransmitter involved in pleasure, but it’s a really, really important one. And if you want to think about something that most people don’t know about dopamine, which I think is really interesting, is that we are always releasing dopamine at a kind of tonic baseline rate. And it’s really the deviation from that baseline rather than like hits of dopamine in a vacuum that make a difference. So when we experience pleasure, our dopamine release goes above baseline. And likewise, dopamine can go below that tonic baseline. And then we experience a kind of pain.

DR. ANDREW HUBERMAN: Interesting. So is it fair to say that one’s baseline levels of dopamine, how frequently we are releasing dopamine in the absence of some, I don’t know, drug or food or experience, just sitting being is that associated with how happy somebody is their kind of baseline of happiness or level of depression?

DR. ANNA LEMBKE: There is evidence that shows that people who are depressed may indeed have lower tonic levels of dopamine. So that’s a really reasonable thought. And there’s some evidence to suggest that that may be true. The other thing that we know, and this is really kind of what the book is about, is that if we expose ourselves chronically to substances or behaviors that repeatedly release large amounts of dopamine in our brain’s reward pathway, that we can change our tonic baseline and actually lower it over time as our brain tries to compensate for all of that dopamine, which is more really than we were designed to experience.

DR. ANDREW HUBERMAN: Interesting. And is it the case that our baseline levels of dopamine are set by our genetics, by our heredity?
