Addiction is a complex, multifaceted phenomenon that has been described variously as a disease, disorder, syndrome, obsessive-compulsive behaviour, learned behaviour, or spiritual malady. Modern scientific understanding emphasises addiction as a chronic brain disorder shaped by neurobiological changes, learning, and social context. This article examines each conceptualisation and presents an integrated definition that aligns with current neuroscience, psychological, and public health evidence.
No single label fully captures addiction’s complexity; each highlights certain truths while overlooking others.
From a medical perspective, disease is the closest match. Addiction involves persistent neurobiological changes in reward, stress, and self-control circuits, increases relapse risk over years, and shows substantial genetic vulnerability (~50–60%) (NIDA, 2018; Heilig et al., 2021). Treatments improve outcomes but rarely “cure” the condition. This framing is used by the American Society of Addiction Medicine (ASAM), NIDA, WHO ICD-11, and DSM-5-TR (as “Substance Use Disorder”) (NIDA, 2018).
Disorder is also scientifically accurate and slightly less medicalised. DSM-5’s “Substance Use Disorder” captures behavioural, psychological, and biological criteria and recognises functioning and harm rather than framing addiction strictly as a lifelong disease (Heather, n.d.; Heilig et al., 2021).
Addiction may be described as a syndrome because it is a cluster of symptoms with behavioural and physiological manifestations, without a single causative factor. However, the term is too generic for practical use outside clinical texts (Blithikioti et al., 2025).
Addiction involves learning, habit formation, and compulsion through reinforcement of rewarding behaviours (Hyman, 2005; Hausotter, 2013). Yet describing it solely as learned behaviour ignores genetic predisposition, neuroadaptation, withdrawal, and social factors.
Some mutual-aid traditions characterise addiction as a spiritual malady. While this may be meaningful for individuals, it is not scientifically explanatory: addiction can be adequately explained via biological, psychological, and social mechanisms (Lewis, 2017).
The most accurate contemporary description of addiction is:
“A chronic, relapsing disorder of brain circuits involved in reward, stress, and self-control, shaped by learning, environment, and social context”.
This definition encompasses:
In short, addiction is best understood as a bio-psycho-social condition that is treatable and sometimes reversible, rather than a deterministic, lifelong curse.
Repeated substance use alters structural and functional brain circuits involved in reward, stress, motivation, memory, and self-control (Nwonu et al., 2022; NIDA, 2018). These changes can persist long after use stops, explaining why addiction is more than a matter of “bad habits” or weak will (NIDA, 2025).
Addiction is often chronic and relapsing. Even after long periods of abstinence, cues and stressors can trigger relapse (Meurk et al., 2014; SAMHSA, 2023). Key regions implicated include the basal ganglia (habit formation), extended amygdala (stress), and prefrontal cortex (decision-making) (Kirby et al., 2024). Nevertheless, many individuals achieve stable remission, highlighting heterogeneity in clinical outcomes (Heilig et al., 2021).
Addiction exploits neural mechanisms of learning and memory: rewarding behaviours are repeated and consolidated into habits, with cues triggering compulsive responses even when the substance’s reward diminishes (Hausotter, 2013; Lewis, 2017). This intertwines biological disorder and learned behaviour.
Some scientists caution that framing addiction strictly as a brain disease is simplistic:
Thus, while the disease model is powerful, it does not fully represent addiction’s heterogeneity or socio-psychological dimensions.
Addiction is treatable, not simply curable. Interventions combining pharmacological and behavioural approaches, alongside social support, can foster long-term recovery (Liu & Li, 2018; Heilig et al., 2021). Like other chronic conditions, management — rather than elimination — is often the realistic goal (NIDA, 2018). Neural circuits can gradually readjust, particularly when environmental and personal factors support recovery.
Addiction is a learned, compulsive brain disorder with chronic potential, shaped by neurobiological, psychological, social, and environmental factors. Recognising addiction as both a disorder and a behavioural learning condition avoids extremes: it is neither an unchangeable fate nor merely a moral failing. This integrated perspective supports nuanced understanding, compassionate care, and effective treatment strategies.

Well, hello and good morning, afternoon, and evening readers. I truly hope you’re swimming in the pleasantries of life rather than keeping your head above water in the unpleasant swamp. HOPE = Hold On Pain Ends. And there’s generally a learning or personal growth that comes after the storm of every painful experience, even if it’s simply greater empathy and compassion for others.
Today’s the day to learn or remember the fallacies of the human mind. I am not as smart as I look, haha. Have you heard of heuristics before? In cognitive psychology, a heuristic is a mental “shortcut” that allows people to solve problems and make judgments quickly and efficiently. They can be very helpful in many situations, but they can also lead to cognitive biases, errors in thinking, and even perhaps without the mental shortcut, our thinking is often filled to the brim with cognitive distortions, assumptions and fallacies (faults). Awareness raising is probably the first step to identify our own cognitive traps and also identify them in others. Cognitive errors are natural – we all have them. Below are some cognitive distortions/errors to be aware of when we reflect on our interactions with people, during personal reflection, and when making meaningful decisions or judgements.
Again, personalisation is an egocentric error in cognition. “Of course it has to do with me”, we think. It makes sense that we personalise things. We are the star of our own show, our own narrative. If you personalise something, it means we’ve directly influenced it – we are the primary cause. This may elicit internal pain, shame or guilt, so what’s the pay-off? Personalisation is a cognitive error that offers us the illusion of control e.g., “If we caused it then we will learn how to not cause it again, and maybe even undo what we have caused”. If you think about it, personalising something is something children do. Remember, there are infinite variables in any situation to take full credit of the outcome. That being said, it is responsible and mature to reflect objectively on the influence of our behaviour and what we can learn about our shortcomings.
Blame deserves it’s own blog post but in short, it can be defined as a defence mechanism to protect the self from feeling some unwanted emotion or thinking something unacceptable in relation to the “self”. Blaming provides a way of devaluing others, an the pay-off or reinforcement the blamer receives is a sense of superiority. It protects our ego from feeling responsible for something, and protects us from feeling guilt or shame. Perfectionists are very good at blaming others, and themselves. Even if you genuinely think faulting someone or something is valid, remember that no one is perfect. Recognise that you are human and others are fallible humans. As they say in recovery, “there is a bit of bad in the best of us and a bit of good in the worst of us“. We may have internalised from society and culture that we couldn’t make mistakes (because we receive “punishment” for making mistakes) but we must move beyond that now. As adults, we need to get real. Validate your experience because it may be very disappointing when we don’t meet others or our own expectations. We must nurture and care for the wounded child. Lets attend and befriend to our shortcomings and accept we are not superhuman. Learn to expect you will make mistakes. Failure is kind of an illusion, isn’t it? Or maybe a social construct? “Failure” is really learning – replace ‘failure’ with the word ‘feedback’. Would a cat or dog blame them self for a “mistake”? In the minds of animals, there’s no such concept as failure or a mistake.

Hello readers! A few of the cognitive styles below were mentioned in my last post. As humans, we have a tendency to forget things so a bit of revision can be useful.
Many people have cognitive processes that result in overall unhelpful thinking styles that they tend to apply globally across situations and which may result in emotional distress (such as depression or anxiety) or unhelpful behaviours (such as anger or avoidance). Some of the most problematic thinking styles are listed in the extract below.
Mental Filter: This thinking styles involves a “filtering in” and “filtering out” process – a sort of “tunnel vision”, focusing on only one part of a situation and ignoring the rest. Usually this means looking at the negative parts of a situation and forgetting the positive parts, and the whole picture is coloured by what may be a single negative detail.
Jumping to Conclusions: I’m sure you’ve heard people say on television, “Don’t jump to conclusions” or “The truth is we just don’t know yet”. We jump to conclusions when we assume that we know what someone else is thinking (mind reading) and when we make predictions about what is going to happen in the future (predictive thinking).
Personalisation: This involves blaming yourself for everything that goes wrong or could go wrong, even when you may only be partly responsible or not responsible at all. You might be taking 100% responsibility for the occurrence of external events.
Catastrophising: Catastrophising occurs when we “blow things out of proportion” and we view the situation as terrible, awful, dreadful, and horrible, even though the reality is that the problem itself is quite small. A helpful restructuring of this cognition is to ask yourself if the situation will still be awful, terrible, or dreadful in a month. There may be ongoing consequences or stress involved if you lose a job or a relationship ends, so validate the experience you are having but also take a look at the big picture. What’s the worst that could happen? Why is the worst so “bad”? And if you are being realistic about the issue, reach out for some help if you can.
Black & White Thinking: This thinking style involves seeing only one extreme or the other. You are either wrong or right, good or bad and so on. There are no in-betweens or shades of grey.
Should-ing and Must-ing: Sometimes by saying “I should…” or “I must…” you can put unreasonable demands or pressure on yourself and others. Although these statements are not always unhelpful (e.g. “I should not get drunk and drive home”), they can sometimes create unrealistic expectations.
Overgeneralisation: When we overgeneralise, we take one instance in the past or present, and impose it on all current or future situations. If we say “You always…” or “Everyone…”, or “I never…” then we are probably overgeneralising.
Labelling: We label ourselves and others when we make global statements based on behaviour in specific situations. We might use this label even though there are many more examples that aren’t consistent with that label.
Emotional Reasoning: This thinking style involves basing your view of situations or yourself on the way you are feeling. For example, the only evidence that something bad is going to happen is that you feel like something bad is going to happen. I live with anxiety and it can be debilitating at times. I use my “wiser thinking” or “rational thinking” to evaluate whether I am operating from an emotional mindset. You might ask yourself: “What’s the evidence?”, “Does the past necessarily predict the future?”, “Am I angry or fearful right now because that might be clouding my judgement?”. It can be helpful to talk to someone who isn’t caught in your emotional headspace, or perhaps wait for the emotion to subside to think about the situation again.
Magnification and Minimisation: In this thinking style, you magnify the positive attributes of other people and minimise your own positive attributes. It’s as though you’re explaining away your own positive characteristics.
