In this episode of the Huberman Lab, Dr. Anna Lembke explores the neurobiology of addiction through the lens of dopamine, a key neurotransmitter involved in pleasure and reward. She explains how dopamine levels fluctuate above and below baseline during pleasurable activities, and how repeated exposure to dopamine-spiking behaviors can lead to addiction, anxiety, and depression-like symptoms.
The discussion covers practical approaches to overcoming addiction, including the importance of a 30-day abstinence period for resetting the brain's dopamine system. Dr. Lembke and Huberman examine various treatment methods, from psychedelic-assisted therapy to specific strategies for managing technological addictions like social media use, while considering the biological principles underlying addiction recovery.

[restricted term], a crucial neurotransmitter, bridges the gap between neurons to enable communication related to pleasure and reward. The neurotransmitter operates on a baseline rate, with deviations above this baseline creating pleasure and drops below it resulting in pain. This baseline level, influenced by both genetics and experiences, can be modified over time through chronic exposure to substances or behaviors that release large amounts of [restricted term].
When engaging in pleasurable activities, the brain releases [restricted term], followed by an immediate attempt to maintain equilibrium by decreasing [restricted term] receptors and transmission. According to Anna Lembke's research, repeatedly seeking these [restricted term]-spiking behaviors without adequate recovery time can lead to a deficit state, manifesting as anxiety, irritability, and depression-like symptoms. In severe cases of addiction, the brain may become unable to restore its natural [restricted term] balance, resulting in a chronic state of pain and deficiency.
A 30-day abstinence period is crucial for resetting the brain's [restricted term] system. While the first two weeks typically bring significant discomfort and cravings, by weeks three and four, most individuals experience mood stabilization and improved well-being. However, even in positive situations, relapse remains a risk as [restricted term] spikes from positive events can unexpectedly trigger cravings and potential substance reuse.
Psychedelic-assisted therapy has shown promise in treating addiction and trauma in controlled clinical settings. However, Andrew Huberman expresses skepticism about using extreme chemical experiences like MDMA to treat drug addiction, suggesting it might contradict [restricted term] biology principles. For technological addictions, particularly social media, Lembke emphasizes the need for different treatment approaches, recommending intentional boundaries and physical barriers to prevent harmful usage patterns.
1-Page Summary
[restricted term] plays a crucial role in our understanding of neurobiology, as it influences our experiences of pleasure, pain, and motivation.
This neurotransmitter serves as a crucial component for neural communication. [restricted term] bridges the gap between neurons, enabling the presynaptic neuron to send messages to the postsynaptic neuron.
[restricted term] is released at a tonic baseline rate, and it's the deviation from this baseline that determines whether an individual experiences pleasure or pain. When the level of [restricted term] release rises above the baseline, pleasure is felt; conversely, when the release dips below the baseline, pain is felt. Individuals who suffer from depression may experience lower tonic levels of [restricted term].
The baseline [restricted term] level appears to be established early on, influenced by genetics. However, experiences, including chronic exposure to substances or behaviors that release sizeable [restricted term] amounts, can modify and lower the baseline level over time. These changes can have significant effects on temperament and susceptibilities such as addiction risk.

Dopamine's Role in Neurobiology: Pleasure, Pain, and Motivation
Understanding addiction involves exploring how pleasure, pain, and the brain's [restricted term] system interact.
Pleasure and pain have a unique relationship in the brain, sharing the same neural space. When one engages in pleasurable behaviors, such as watching YouTube videos, a release of [restricted term] occurs in the brain. This spike of [restricted term] is immediately met by the brain's attempt to maintain equilibrium, typically by decreasing the number of [restricted term] receptors and the transmission of [restricted term].
The brain's effort to down-regulate [restricted term] receptors and transmission is a response to maintain homeostasis after a surge of pleasure. The same mechanism applies even to the anticipation of drug use, which can cause a mini spike of [restricted term], setting the stage for pleasurable experiences.
However, repeatedly seeking pleasurable, [restricted term]-spiking behaviors without sufficient recovery time can lead to a [restricted term] deficit. This deficit can manifest as anxiety, irritability, insomnia, and dysphoria—a state similar to clinical depression. Such symptoms are often accompanied by a mental preoccupation with recapturing the high to regain balance.
Repeated overindulgence in high-reward behaviors or substances could disrupt the brain's ability to restore its [restricted term] equilibrium, fixating it in a chronic state of pain and [restricted term] deficiency.
In such a deficit state, the brain struggles to regain homeostasis, contributing to a lack of joy and other depressive symptoms. According to Lembke, individuals with severe addiction might experience a permanently shifted "balance" toward pain, where the brain’s homeostatic abilities are impaired, even with sustained ab ...
Mechanisms Underlying Addiction and Dopamine Reward System
Understanding neurobiological balance is crucial in mastering control over one's impulses and potentially addictive behaviors. A 30-day abstinence period is key to resetting the brain’s [restricted term] system.
It takes approximately 30 days of abstinence for the brain to reset reward pathways and regenerate [restricted term] transmission. By avoiding high-[restricted term] substances or behaviors during this time, the brain can rebuild its own [restricted term] levels and restore balance.
Patients typically feel worse during the first two weeks of abstinence, plagued by significant discomfort and cravings due to the absence of the accustomed high-[restricted term] substances or behaviors.
After the initial two weeks of hardship, however, the brain and mood begin to stabilize. By week four, most individuals start to feel much better than they did prior to stopping the substance use. From days 21 through 30, [restricted term] begins to be released normally again, responding to ordinary stimuli such as the taste of a good cup of coffee, rather than exclusively to addictive behaviors.
Despite advances, recovery is always at risk, and even positive situations can inadvertently cause setbacks.
The [restricted term] assoc ...
Overcoming Addiction and Resetting the Dopamine System
An exploration into the use of psychedelics for treating addiction reveals both potential breakthroughs and risks, while also touching on the challenges of managing technological addictions.
Psychedelic-assisted therapy has shown promise in treating addictions and trauma, with studies suggesting transformative effects in controlled clinical environments.
Clinical studies have indicated that, under controlled conditions, psychedelic experiences can be transformational for those addicted to substances like alcohol. Individuals given high doses of psilocybin or MDMA in these studies, paired with regular psychotherapy, can gain new positive perspectives on their lives. These profound experiences often lead to spiritual or values-based realizations, prompting patients to reconnect with their families and reconsider destructive habits, such as excessive drinking.
Andrew Huberman expresses skepticism about the approach of using extreme chemical experiences like MDMA to treat drug addiction. He suggests it might contradict [restricted term] biology principles and potentially exacerbate addictions. Additionally, there is concern about the long-term impact of such short-term interventions given addiction's chronic nature.
Outside the controlled environment of clinical settings, there is a real risk of disastrous outcomes from self-administered psychedelics. Individuals may seek spiritual awakening through practices like microdosing, risking harm without therapeutic guidance. Furthermore, the public might misconstrue these treatments as universally safe and not recognize the importance of a controlled setting for their use.
Technological addictions, particularly to soci ...
