A Stanford psychiatrist says the same brain circuits that hook people on opioids are now hooked on phones, food, and shopping — and she has a plan to break the cycle.
Story Snapshot
- Dr. Anna Lembke, a Stanford addiction medicine specialist, lays out how modern life overloads the brain’s reward system.
- She argues that near-constant access to pleasure — through screens, food, and substances — pushes many people into compulsive patterns.
- Her framework ties clinical addiction science to everyday habits millions of Americans recognize in themselves or their kids.
- Medical bodies still debate how far the label “addiction” should stretch beyond drugs, alcohol, and gambling.
A Stanford Doctor’s Front-Row View of Addiction
Dr. Anna Lembke holds several titles at Stanford University School of Medicine. She serves as Medical Director of Addiction Medicine, Program Director of the Stanford Addiction Medicine Fellowship, and Chief of the Stanford Addiction Medicine Dual Diagnosis Clinic. She treats patients struggling with opioids, alcohol, and what she calls “digital drugs” — compulsive use of phones and apps that trap people in a trancelike state.
Lembke built her reputation on a simple but unsettling idea. The brain does not separate a drug high from a dopamine rush triggered by a notification, a sugary snack, or a winning bet. Each one presses the same reward buttons. When people chase those rushes nonstop, the brain adjusts by dulling its own pleasure response, leaving them needing more just to feel normal.
Why Pleasure Now Comes With a Price
Lembke’s bestselling book, Dopamine Nation, explains why constant access to pleasure can backfire. She describes the brain as running on a balance scale. Pleasure tips it one way, pain tips it back. Overindulge today, and the brain overcorrects tomorrow, leaving people anxious, irritable, or empty once the high fades.
That cycle, she says, explains more than drug abuse. It explains why teenagers melt down when parents take their phones, why adults doomscroll past midnight, and why some people cannot stop refreshing social media even when it makes them miserable. The behavior looks different, but the underlying brain mechanism works the same way in each case.
Where Doctors Draw the Line on “Addiction”
Not every compulsive habit counts as a clinical addiction, and medical groups disagree on where to draw that line. The American Psychiatric Association’s diagnostic manual places gambling disorder alongside substance addictions but still lists internet gaming disorder as a condition needing more research before full recognition. The World Health Organization’s disease classification recognizes both gambling and gaming disorders, but it does not treat every heavy digital habit as a medical addiction.
That distinction matters for families trying to make sense of a loved one’s behavior. A teenager glued to a game controller is not automatically diagnosable, even if the habit worries parents. Researchers say more study is needed before conditions like compulsive shopping or nonstop social media use get the same formal status as gambling or substance disorders.
Practical Steps Toward Breaking the Cycle
Lembke does not just diagnose the problem; she offers a way out. She recommends periods of total abstinence from the compulsive behavior, often lasting about a month, to let the brain’s reward system reset and rebuild its natural capacity for pleasure. She calls this approach a dopamine fast, and she has outlined it in public talks and teaching sessions aimed at everyday people, not just patients in treatment.
Incredible but true. When co-dependent people finally give up attempting to control addict family members the addicts almost always start their recovery/quittimg process. Dr Anna Lembke MD is an expert in dopamine and addiction @StanfordMed

She also pushes people to sit with discomfort instead of numbing it immediately. Cravings, boredom, and anxiety fade on their own if given time, she says, but constant distraction never lets that happen. For many Americans exhausted by headlines, inflation worries, and a culture that profits from grabbing their attention, her message lands as a rare, practical call to take back control of one’s own mind.
