If you're in crisis right now, this page is the wrong place. In Ireland and the UK, Samaritans is 116 123 — free, 24 hours. If you're at immediate risk, go to A&E or call 999 or 112. If you are physically dependent on alcohol, read the safety warning below before you stop drinking.
The single most useful fact about addiction treatment is that effective treatments exist, they are medications as well as therapies, and most people who would benefit are never offered them.
The second most useful fact is that willpower is not on the list — not because people lack it, but because it isn't the mechanism the condition runs on.
What the diagnosis actually is
Substance use disorder is diagnosed on a set of eleven criteria covering four areas: impaired control, social impairment, risky use, and pharmacological features (tolerance and withdrawal). Severity is graded by how many are present — two to three is mild, four to five moderate, six or more severe.
Two things worth pulling out of that structure.
Tolerance and withdrawal are only two of the eleven. You do not need to be physically dependent to have a substance use disorder, which is why "I don't get withdrawal" isn't the reassurance people take it for.
And the impaired-control criteria are the heart of it — using more or longer than intended, repeated unsuccessful efforts to cut down, craving, continuing despite knowing the harm. That cluster describes a control problem, not a preference. Someone repeatedly trying to stop and failing is meeting a diagnostic criterion, not demonstrating a character flaw.
Why the willpower framing does damage
It isn't just unkind, it's inaccurate in a way that has consequences.
Repeated substance use produces durable changes in the brain circuits handling reward, motivation, stress and inhibitory control. The practical upshot is that the drive to use becomes progressively less like wanting something and more like relieving something — and it persists after the pleasure has gone, which is precisely what people describe and precisely what makes no sense under a willpower model.
The framing matters because of what follows from it. If addiction is a moral failure, the intervention is shame, and shame drives concealment. If it's a treatable condition, the intervention is treatment — and the evidence below is about treatment.
None of that removes agency, and people in recovery are usually the first to say so. It relocates where the effort is useful: not in resisting harder, but in getting to something that works.
Opioid use disorder: the clearest evidence in the field
This is where the numbers are strongest, and they are striking.
Treatment with agonist medication — methadone or buprenorphine — is associated with an estimated reduction in mortality of around 50%. Retention on either medication is linked to substantially decreased risk of both all-cause and overdose death.
On staying in treatment, people receiving methadone are more than four times as likely to remain in treatment as those on placebo, with twelve-month retention ranging from 37% to 91% depending on the setting. Extended-release naltrexone performs much worse in the real world — one figure puts adherence at 10.5% at six months.
And the finding that most contradicts intuition: all studies of tapering and discontinuation show very high rates of relapse. Coming off the medication, even successfully and gradually, is the point at which risk returns.
That reframes a common objection. Agonist treatment is often described — including by people receiving it — as "still being on something." What the mortality data says is that being on it is the thing keeping people alive, and that treating it as a temporary staging post towards abstinence is not supported by the evidence. It is closer to how we think about medication for any other chronic condition.
Alcohol: the medications almost nobody is offered
Three medications have a real evidence base in alcohol use disorder, and the striking thing is how rarely they come up:
- Naltrexone — reduces heavy drinking and craving. Notably, it can be used with a goal of reduced drinking rather than only total abstinence, which suits a lot of people better.
- Acamprosate — supports maintenance of abstinence once someone has stopped.
- Disulfiram — works by making drinking acutely unpleasant, and is effective under supervision.
Alongside those: CBT, motivational approaches, contingency management, and mutual-aid groups including the twelve-step programmes, which have better evidence than their reputation among sceptics suggests.
If you have tried to cut down repeatedly and not managed it, "have you considered medication" is a reasonable question to put to a GP — and one many people have never been asked.
A genuine safety warning, and the most important paragraph here
If you are physically dependent on alcohol, do not stop abruptly without medical advice. Alcohol withdrawal is one of the few withdrawals that can kill. It can cause seizures and delirium tremens, and it needs medical supervision — often with medication to cover the withdrawal itself.
Signs that this applies to you: shaking, sweating, nausea, anxiety or a racing heart in the morning or when you haven't drunk for a while, or needing a drink to steady yourself. If any of that is familiar, the safe route is a doctor before you stop, not willpower and a weekend.
The same applies to benzodiazepines. Abrupt cessation is dangerous.
Nicotine, briefly
Worth including because it's the most lethal of the lot at population level and the treatments are genuinely good. Varenicline and nicotine replacement both work, combination NRT outperforms single-product NRT, and behavioural support on top of medication improves the odds further. Most quit attempts are made unaided, which is also the approach with the lowest success rate.
What co-occurs, and why it matters
Substance use disorders travel with other conditions far more often than chance, and treating one while ignoring the other tends to fail.
PTSD is among the strongest associations, and self-medication is extremely common — the guideline position is worth knowing, including that benzodiazepines are strongly recommended against and that cannabis is too.
Anxiety and depression — the distinction between anxiety as a feeling and as a disorder matters here, because alcohol reliably lowers anxiety for hours and raises it for the following day, which is an almost perfect trap.
Chronic pain — the overlap with opioid use is obvious, and the pain guidelines now advise against starting opioids for chronic primary pain partly for this reason.
ADHD — associated with higher rates of substance use disorder, and often undiagnosed in adults. Why so many were missed.
And sleep. Disrupted sleep is both a driver and a consequence, and it is one of the most common relapse triggers. CBT-I has better evidence than anything you can buy, and it has been studied in people in recovery.
Where we sit — and this one is uncomfortable
Nothing Proco sells treats addiction. No supplement does, and there is nothing in our range that belongs anywhere in this article.
We want to be specific about two failure modes in our own category, because both are common.
"Detox" and "liver support" products. These are sold heavily to people who are drinking too much, and the offer is implicitly that you can offset the damage rather than reduce the drinking. There is no supplement that makes heavy drinking safe, and a product that reduces someone's worry without reducing their intake has made things worse, not better.
The more consequential version: a supplement marketed for withdrawal or "cutting down" is actively dangerous in alcohol dependence, for the reason in the safety warning above. This is a medical situation.
And our own products and alcohol. Several of them don't combine well with it — we've set out where they stand. More broadly, the "moderate drinking is protective" story has not held up, and the sleep effects are measurable and bad.
One thing worth knowing that is genuinely nutritional rather than a supplement pitch: heavy drinking depletes thiamine, and thiamine deficiency can cause serious, partly irreversible neurological damage. That is a reason for medical supervision — thiamine replacement is standard in alcohol withdrawal management — not a reason to buy a B-complex. Alcohol-related nerve damage works through the same territory.
If you're reading this about yourself
Two things that seem to help more than anything else at this stage.
Ask specifically about medication. For alcohol, name naltrexone or acamprosate. For opioids, ask about methadone or buprenorphine. These are standard treatments and asking for them by name shortens a conversation that otherwise tends to stall at advice.
And reduced drinking is a legitimate goal. Treatment is often presented as all-or-nothing, which stops people starting. Naltrexone in particular is used with reduction as the aim. If total abstinence feels impossible, that is not a reason to wait — it's a reason to say so at the appointment.
If it's someone else you're worried about: the thing that reliably doesn't work is shame, and the thing that does is staying in contact and being there when they're ready. Family support services exist independently of whether the person is in treatment.
This article is not medical advice and cannot diagnose a substance use disorder. Do not stop drinking abruptly if you may be physically dependent on alcohol, and do not stop a prescribed benzodiazepine or opioid abruptly — both can be dangerous. Treatment decisions belong with a clinician.
