Eating Disorders DSM-5

Addiction fundamentally alters the brain’s reward and decision-making systems through well-documented neurobiological mechanisms. When substances like drugs (including alcohol and nicotine) are consumed, they trigger massive releases of dopamine in the brain’s reward circuit, particularly in areas like the nucleus accumbens and ventral tegmental area. With repeated exposure, the brain adapts by reducing natural dopamine production and decreasing the number of dopamine receptors, creating tolerance and requiring increasingly larger amounts of the substance to achieve the same effect. This neuroadaptation hijacks the brain’s natural reward system, making everyday activities less rewarding while the addictive substance becomes disproportionately important.

Over time, addiction also impairs the prefrontal cortex, the brain region responsible for executive functions like decision-making, impulse control, and weighing long-term consequences. This creates a neurological double-bind: the midbrain structures driving craving and drug-seeking behaviour become hyperactive, while the prefrontal systems that would normally regulate these impulses become weakened. Chronic substance use also disrupts stress response systems, making individuals more vulnerable to relapse during difficult periods. These changes help explain why addiction is recognised as a chronic brain disease rather than simply a matter of willpower – the neuroplastic changes can persist long after substance use stops, though the brain does have remarkable capacity for recovery with sustained abstinence and appropriate treatment.

The Challenge of Stopping

The challenge of stopping stems from the profound neurobiological changes addiction creates in the brain’s fundamental survival systems. The brain essentially learns to treat the addictive substance as necessary for survival, similar to food or water. When someone tries to quit, they face intense physical withdrawal symptoms as their neurochemistry struggles to return to homeostasis, combined with psychological cravings that can persist for months or years. The damaged prefrontal cortex makes it extremely difficult to override these powerful urges with rational decision-making, while stress, environmental cues, and emotional states can trigger automatic drug-seeking responses that feel almost involuntary. This creates a cycle where attempts to quit often lead to temporary success followed by relapse, which many interpret as personal failure rather than recognising it as part of the neurological reality of the condition.

Addiction appears progressive because tolerance drives escalating use over time, while the brain’s reward system becomes increasingly dysregulated. What begins as recreational use gradually shifts to compulsive use as natural dopamine production diminishes and neural pathways become more deeply entrenched. The condition typically follows a predictable pattern: initial experimentation leads to regular use, then to use despite negative consequences, and finally to compulsive use where the person continues despite severe impairment in major life areas. Additionally, chronic substance use often damages the brain regions responsible for insight and self-awareness, making it harder for individuals to recognise the severity of their condition. The progressive nature is also influenced by external factors – as addiction advances, people often lose social supports, employment, and housing, creating additional stressors that fuel continued use and make recovery more challenging.

Understanding addiction when you’re not “addicted” to alcohol or other drugs

The difficulty in understanding addiction, even among people with their own compulsive behaviors, stems from several key differences in how these conditions manifest and are perceived. While behaviors like sugar consumption, social media use, or shopping can indeed activate similar dopamine pathways, they typically don’t create the same level of neurobiological hijacking that occurs with substances like alcohol, opioids, or stimulants. Addictive drugs often produce dopamine surges 2-10 times greater than natural rewards, creating more profound and lasting changes to brain structure and function. Additionally, many behavioral compulsions allow people to maintain relatively normal functioning in major life areas, whereas substance addiction typically leads to progressive deterioration across multiple domains – relationships, work, health, and legal standing.

The social and cognitive factors also create barriers to understanding. Most people can relate to losing control occasionally – eating too much dessert or spending too much time scrolling their phone – but these experiences usually involve temporary lapses that can be corrected relatively easily through willpower or environmental changes. This creates a false sense of equivalency where people think “I can stop eating cookies when I want to, so why can’t they just stop drinking?” They don’t grasp that addiction involves a qualitatively different level of brain change where the substance has become neurobiologically essential, not just psychologically preferred. There’s also often a moral lens applied to addiction that doesn’t exist for other compulsive behaviours – society tends to view overconsumption of legal, socially acceptable things as personal quirks or minor character flaws, while addiction to illegal substances or excessive alcohol use carries heavy stigma and assumptions about moral failing, making it harder to see as a medical condition requiring treatment rather than simply better self-control.

A Word On Nicotine (Tobacco Products)

Yes, nicotine absolutely does release large amounts of dopamine, making it highly addictive despite being legal and socially accepted in many contexts. Nicotine causes an increase in dopamine levels in the brain’s reward pathways, creating feelings of satisfaction and pleasure.Research shows that nicotine, like opioids and cocaine, can cause dopamine to flood the reward pathway up to 10 times more than natural rewards.

This helps explain why nicotine addiction can be so powerful and difficult to overcome, even though people often view smoking or vaping as less serious than other forms of substance addiction. Repeated activation of dopamine neurons in the ventral tegmental area by nicotine leads not only to reinforcement but also to craving and lack of self-control over intake. The addiction develops through the same basic mechanisms as other substances – as people continue to smoke, the number of nicotine receptors in the brain increases, requiring more of the substance to achieve the same dopamine response.

What makes nicotine particularly insidious is its legal status and social acceptance, which can make people underestimate its addictive potential. The rapid delivery of nicotine to the brain (within 10-20 seconds when smoked) creates an almost immediate reward that strongly reinforces the behaviour. This is why many people who successfully quit other substances still struggle with nicotine, and why nicotine addiction often serves as a gateway that primes the brain’s reward system for addiction to other substances.

Shame is a complex and powerful (“contracting” and belittling) emotion that can have a significant impact on our mental health and how we navigate the world and interact with people. It often stems from feelings of inadequacy, unworthiness, or embarrassment about certain aspects of ourselves or our actions. This may not mean much to you right now … but that is all bullshit. I have worked with many people experiencing extreme toxic shame, and they are intrinsically beautiful people. Understanding the root causes of toxic shame is an essential first step in creating a healthy relationship with it. It’s crucial to recognize that experiencing shame is a universal human experience, and it does not define your worth as a person. Oftentimes, our shame is a projection of what we believe other people think about us, or it is an internalised belief (script, attitude etc.) that we learned from painful and scary life experiences. I want to preface the following by acknowledging that shame can be healthy. Without shame, we may develop unhealthy levels of egotism, narcissism, arrogance, and superiority.

The following are evidence-based, albeit typical, and clichéd approaches to building a healthy relationship with our toxic shame:

Challenge Negative Thoughts

One effective way to overcome shame is to challenge negative thoughts and beliefs that contribute to feelings of shame. This can feel exhausting! To be constantly vigilantly of our thinking, hence, noticing and letting thoughts stream through the mind will be necessary here. In 12-step fellowships, they would suggest to “let the go” and “hand them over”. For example, saying to yourself “This is not for me right now and I’ll hand it over to the universe just for now”. We do not always have the energy to challenge our negative thoughts. You can ‘compartmentalise them’, or say, “not right now”, or even say “thank you for making me aware of this and I may reflect on this when I have more time”. Challenging negative thoughts involves identifying and questioning the critical inner voice that fuels self-criticism and self-doubt. By practicing self-compassion and cultivating a more positive self-image, you can begin to counteract the destructive effects of shame.

Practice Self-Compassion

Self-compassion (and kindness) is a key component of overcoming shame. Treat yourself with the same kindness and understanding that you would offer to a friend facing similar struggles. Underpinning our shame is a profound fear that we will be rejected i.e., lose a job, be ignored by friends, lack confidence to make meaningful connections and intimacy. Acknowledge your imperfections without harsh judgment and remind yourself that it’s okay to be imperfect. We don’t often see others’ imperfections, and when we do, we think theirs are tolerable or not that bad compared to ours. Developing self-compassion can help us build resilience in the face of shame and cultivate a healthier relationship with yourself. I say again, every client I have worked with has shown me their absolute beautifulness by talking about their imperfections and showing me their self.

Seek Support

It’s essential to reach out for support when dealing with shame. This can be terrifying – paralysing even – and many people have reached out in the past and the outcome has made us feel even worse. Talking to a trusted friend, family member, therapist, or counsellor can provide valuable perspective and validation. Sharing your feelings of shame with others can help you feel less isolated and alone in your struggles. Additionally, professional help can offer guidance and strategies for coping with shame in a healthy way.

Cultivate Self-Acceptance

Practicing self-acceptance involves embracing all aspects of yourself, including those that may trigger feelings of shame. Recognize that nobody is perfect, and everyone makes mistakes. By accepting your vulnerabilities and imperfections, you can reduce the power that shame holds over you. Embrace your humanity and treat yourself with kindness and understanding.

Engage in Positive Activities

Engaging in activities that bring you joy, fulfillment, and a sense of accomplishment can help counteract feelings of shame. Pursue hobbies, interests, or goals that boost your self-esteem and remind you of your strengths and capabilities. Surround yourself with supportive people who uplift you and encourage your personal growth.

Practice Mindfulness

Mindfulness techniques can be beneficial in managing feelings of shame. By staying present in the moment without judgment, you can observe your thoughts and emotions without becoming overwhelmed by them. Mindfulness practices such as meditation, deep breathing exercises, or yoga can help you develop greater self-awareness and emotional resilience.

These strategies, actions, and ways of thinking will take practice, practice, and more practice. It is not easy. Based on my own experience, I needed a group of people on my path who I could rely on and practice with many times over, and then I started practising on my own. I still connect with the people living my recovery. I take breaks from them when I need to, but I always reconnect because loneliness will breed more shame.

I would infer that you may be depleted in some area of your life. Generally, when I am having any of these experiences I can recognise that my basic needs, and possibly even transformative, needs are not met. My basic needs are food and water, adequate sleep, shelter and safety, social connection (belonging), and esteem needs (e.g., self-respect, self-worth, self-competence, mastery and achievement, integrity, sense of freedom and independence etc.). Perhaps only when all my deficiency needs are met, and I’m experiencing dissatisfaction with my growth needs, do I feel Restless, Irritable, and Discontent in this area of my life – however I assume some would argue that if I am feeling that way when attending to my growth needs, then I may have slipped back to Esteem Needs. You can look up Maslow’s Hierarchy of Needs for a visual representation if you like, using a search engine. Below is a GIF that I created to educate people on how we can buffer ourselves to vulnerabilities. It’s very telling to go into the body when we haven’t eat for a while, may be we’re running on caffeine, and you can feel the restlessness in the body. We have to fuel up when we’re hungry to buffer ourselves from becoming irritable and restless. If you’re feeling discontent with life, I would suggest a social activity, play time with friends, working on a project of some kind, or getting involved in your community.
