Addiction or habit? What science says about when to seek help (and why it's so hard)

For a while now you have been telling yourself every night: “This is the last one.” The last drink too many, the last joint to get to sleep, the last bet “to win it back”. The next morning brings a strange mixture of guilt and alibis: “it's not that bad”, “I've got it under control”, “I'll quit when work goes better”. And, at the same time, a quiet fear you don't even know how to name: what if this no longer depends on me?

Scenes like this are the starting point for many of the people who end up booking an appointment at a psychology practice. They almost never arrive saying “I have an addiction”. They arrive with a much humbler and much harder question: “is this thing that's happening to me a habit or an addiction?” And behind the question, always, the fear of judgement: from those around them, from the healthcare system and from their own mirror.

Habit or addiction? Science sees it as a continuum

The question “habit or addiction” starts from an idea that clinical psychology abandoned years ago: that there is a qualitative leap between “someone who is in control” and “someone who is addicted”. The DSM-5, the reference diagnostic manual, reframed this in 2013: it merged the old categories of “abuse” and “dependence” into a single substance use disorder, described by 11 criteria (loss of control, growing salience, continuing despite the consequences, tolerance, discomfort when not using…) and degrees of severity: mild (2–3 criteria), moderate (4–5) and severe (6 or more)1.

The practical implication is enormous: an addiction is not something you either have or don't have, but a point on a gradient. You don't need to “hit rock bottom” or fit the stereotype for what is happening to you to deserve professional attention. Even with few criteria there is already a problem that responds well to therapy, and the longer it waits, the heavier it becomes. The same framework applies to behaviours without substances, such as gambling, recognised as an addictive disorder within the manual itself1.

And the loss of control is not a moral issue. The landmark review by Volkow, Koob and McLellan in the New England Journal of Medicine describes addiction as a chronic brain disease, with measurable changes in the reward, stress and self-control circuits2. This takes away no one's agency; what it takes away is blame. It is not a lack of willpower: the brain changes, and that is precisely why therapy, which also changes the brain, works.

Why is it so hard to ask for help: shame as a real barrier

If asking for help were only a rational decision, everyone would do it early. The data say the opposite. In a representative sample of more than 34,000 adults in the United States, people with an alcohol use disorder who perceived more stigma towards alcoholism were less than half as likely to seek treatment (OR = 0.37)3. Shame is not an incidental discomfort: it is, literally, a barrier to accessing help.

And the wait is long. The WHO World Mental Health Surveys, with data from 15 countries including Spain, found that only between 0.9% and 18.6% of people with a substance use disorder sought treatment during the first year of the problem, and that the median delay before the first contact with care reaches 6–14 years in several countries4. Meanwhile, the problem is anything but rare: in the last major wave of the NESARC, alcohol use disorder affected 1 in 8 adults over a 12-month period, and the vast majority never received professional help5.

That is why the way we talk about it matters to us. We don't say “addict” or “junkie”: we say a person with an addiction, because the problem is something that happens to you, not something you are. This is not a cosmetic detail: words that label a health problem as a moral failing are part of the reason people wait years before knocking on a door.

Motivation is not a requirement to start: it is built

There is a very widespread idea that holds many people back: “I'm not convinced enough yet; when I'm sure, I'll seek help”. Research says exactly the opposite. The stages of change model of Prochaska and DiClemente showed that change is a process with phases (precontemplation, contemplation, preparation, action and maintenance) and that ambivalence (wanting it and not wanting it at the same time) is a normal and expected stage, not an excuse or a symptom of failure6.

In fact, one of the interventions with the most accumulated evidence, motivational interviewing, starts exactly here: instead of confronting or persuading, it explores your own ambivalence until change stops being an external order and becomes your own decision. The meta-analysis by Hettema, Steele and Miller (72 clinical trials) found significant effects in the vast majority of studies reviewed, often with few sessions7.

Translated to the consulting room: you don't need to come 100% convinced. You can come with doubts, with motivation and with fear all at once. Working on those doubts is not a prerequisite for therapy; it is the beginning of therapy.

What actually works (and, in most cases, without admission)

The field of psychological treatment for addictions is not a matter of opinion: there are solid meta-analyses on what works. Cognitive behavioural therapy (CBT) (identifying triggers, training alternative responses, preventing relapses) has shown significant effects in a meta-analysis of 53 randomised trials with adults with alcohol or drug use disorders8. Contingency management (incentive systems that reinforce abstinence) is one of the most powerful interventions ever measured in this field9. And even brief interventions, structured conversations of less than an hour, measurably reduce alcohol consumption, according to a Cochrane review of 69 trials with more than 33,000 participants10.

The most surprising finding, however, is another one: for most people, outpatient treatment is as effective as inpatient treatment. A review in Psychiatric Services on intensive outpatient programmes rated the level of evidence as high, with results comparable to residential treatment in multiple randomised trials11. In other words: being admitted is not the only route nor, in itself, the best one. Being able to keep living your life while you do therapy, and practising the change exactly where it is at stake for you, is often an advantage, not a lighter version.

And this does not apply only to substances. In problem gambling, a systematic review of 25 studies found that CBT significantly reduces gambling behaviour, with effects that last up to 24 months after finishing therapy12. The same foundations apply to newer behavioural addictions, such as gaming disorder.

Relapses are part of the process, not of failure

Marlatt's cognitive behavioural model of relapse prevention, a classic in the psychology of addiction, understands relapse not as an event that erases everything, but as a process that begins long before use: high-risk situations, coping strategies that fail, craving, and what it calls the abstinence violation effect, that spiral of “I've already failed, so what's the point” that turns a slip into a fall13. Working on this in therapy changes the script: a slip stops being a verdict and becomes information for adjusting the plan.

The most honest comparison was made by McLellan and his team in JAMA: addiction resembles chronic illnesses such as type 2 diabetes, hypertension or asthma; also in heritability, in treatment adherence and in relapse rates, which sit in the classic 40–60% range when treatment is interrupted14. Nobody says that a person with hypertension has “failed” if their blood pressure spikes when they stop their medication: the plan gets adjusted. With an addiction, the same. Relapsing does not mean that therapy has not worked or that you are not cut out for this; it means the process continues.

And what if the person struggling is someone at home?

An addiction never affects just one person: it reorganises the routines, the silences and the arguments of the whole family. Partners who keep watch, parents who monitor the bank account, children who learn not to bring friends home. And almost always the same feeling of helplessness: “we tell them, we tell them, and they won't take the step”.

Here research brings concrete and hopeful news: the CRAFT programme (Community Reinforcement and Family Training) trains family members and partners in communication, reinforcement of non-using behaviour and self-care, without “intervention”-style confrontation, and in the landmark trial it achieved that around 2 in 3 families (64%) got the unmotivated person to start treatment15. In other words: even if your child, your partner or your sibling doesn't want to come, you can come, and what you learn can genuinely shift the situation.

A compassionate look in the other direction is also worthwhile. Khantzian's self-medication hypothesis, a classic in psychiatry, reminds us that behind many addictions there is not a search for partying but untreated pain: anxiety, insomnia, depression, the aftermath of trauma16. The substance “works” in the short term as an emotional regulator, until it stops working and starts charging interest. That is why therapy that only looks at use falls short: you have to work on what the use was soothing.

What we work on, in practice

Brought into the consulting room, all of this stops being theory. We work in an outpatient format (individual sessions, in person in Girona or online) and adapt the plan to each person: no two processes are alike, and no two reasons behind a pattern of use are alike. The focuses that come up most often are these:

• Understanding the function of use: what it soothes, what it avoids, what it compensates for. Without that map, quitting is switching off an alarm without looking at the fire.
• Triggers and high-risk situations: identifying the contexts, emotions and thoughts that open the door, and training alternative responses before they arrive.
• Managing craving and urges: concrete techniques for riding out the wave of desire without acting on it.
• What lies underneath: anxiety, depression, insomnia or traumatic experiences that use was numbing, treated within the same plan.
• Relapse prevention: a realistic plan for slips, one that turns them into information rather than a spiral of guilt.
• Relationships and family: repairing trust, setting healthy boundaries and, where needed, working with the partner or the parents, including when the person affected does not yet want to come.
