Yes, roughly as well as the best support a health service can give you — and no better. In the strongest test of it, 620 smokers in London were randomly assigned either to Allen Carr's seminar or to the NHS specialist stop-smoking service with behavioural support and medication. At 26 weeks, 19.4% of the Easyway group were still not smoking, against 14.8% on the NHS service, abstinence confirmed by a breath test. The difference wasn't statistically distinguishable from chance.
That is a genuinely good result for a book-and-a-seminar with no medication in it. It is also considerably less than the "twice as effective" line the method is usually sold with. Both halves matter.
What the method actually claims
Carr's argument is that willpower is the wrong tool because the smoker has been sold a false premise. The cigarette isn't a pleasure you're giving up; it's the relief of a discomfort the previous cigarette created. Take away the belief that you're sacrificing something, and there is nothing left to resist.
You will notice this is not a technique. There is no coping strategy, no substitution, no gum. It is an attempt to change what you believe, on the theory that behaviour follows.
That premise is the one we build on too, so read the rest of this with that in mind.
The two trials, and why they disagree
Dublin, 2019. 300 smokers, randomised to the Easyway seminar or to Quit.ie, Ireland's online cessation service. At twelve months, 22% versus 11%, an odds ratio of 2.26 with a confidence interval of 1.22 to 4.21. Roughly double.
London, 2020. 620 smokers, randomised to the Easyway seminar or to a specialist service delivering behavioural support and pharmacotherapy to the national standard. At 26 weeks, 19.4% versus 14.8%, carbon-monoxide verified, analysed by intention to treat. No clear difference.
The two results aren't in conflict. They're answering different questions, and the comparator is the whole answer. Against a website, the seminar wins comfortably. Against a trained counsellor plus medication, it draws.
Which is worth sitting with if you've seen the headline. "Nearly twice as effective" is true — of the trial against the website. Applied to the trial against the specialist service, it isn't. This is the same pattern we describe in how to read a success rate: the number is real, and the comparison it came from is the part that gets dropped.
The London trial was funded by Allen Carr's Easyway International. It was pre-registered, single-blind and overseen by an independent steering committee, which is close to what you would want when a method's owner pays for the research.
What the wider review says
The 2023 systematic review is the sober summary. Six studies, two of them randomised, quit rates between 19% and 51%, every study raising bias concerns, largest sample 620. Its conclusion is that the seminar "may be an effective intervention" and deserves better research. That's a fair reading of where things stand.
Three things the trials don't cover
The book on its own has never been tested this way. Both RCTs studied the live seminar — four and a half to six hours in a room with a facilitator, plus follow-up. That is not what most people mean when they say they tried Allen Carr. If you read the book on a train and it didn't stick, you didn't fail the version that was tested.
It's a single session. Beliefs assembled over a decade get one afternoon. For some people that's exactly enough, which is why the results are as good as they are. For others the idea lands and then daily life quietly puts everything back.
It's mostly cigarettes, mostly Ireland and the UK. No trial of the method has been run in India, and none of them tested it on vapes, hookah or heated tobacco.
What holds up
The mechanism holds up. The 2026 review of quit-smoking apps found, at high certainty, that apps built on psychological and behavioural theory beat apps built on tracking and standard prompts — 1.69 times the seven-day abstinence at three months. Working on what someone believes outperforms counting what they do. Carr got there decades before the evidence did.
The best trial puts the method level with the gold standard. That is a strong result for an approach with no medication in it, and a more useful thing to know than the promise of effortlessness that usually gets printed on the cover.
Where Nicoxit takes it
Same premise, different delivery.
Seven days instead of one afternoon. A belief examined on Tuesday and then tested against Thursday's actual craving settles differently from one dismantled in a single sitting. 31 modules, about 15 minutes a day, 22 exercises and 7 tools — a course, not a tracker, and one that ends.
You keep smoking during the programme. The first instruction is: don't quit yet. That's Carr's instinct exactly — you don't quit and then work out why, you work out why and quitting has less to push against. The nine borrowed beliefs are our version of the same map, and whether the cigarette really relaxes you is the one most people start with.
In your phone, at Indian prices, for what Indians actually use — cigarettes, vapes, hookah and IQOS, each handled as its own thing rather than converted into cigarettes-per-day.
Grounded in MBCT, ACT and implementation intentions, cited openly rather than implied. Day 1 free, tools free, community free. No streak that punishes you for slipping.
His method has two randomised trials behind it, and one of them is good. We'd rather publish our own numbers in time than lean on his.
Carr was right about the mechanism. The room was never the magic.

Frequently asked questions
Does Allen Carr's Easyway actually work?
Two randomised trials say it works about as well as intensive professional support. A 620-person London trial found 19.4% abstinent at 26 weeks with breath-test verification, against 14.8% for the NHS specialist service — not a statistically clear difference. An earlier Dublin trial found 22% against 11% for an online service at twelve months.
What is Allen Carr's success rate?
Published studies report quit rates between 19% and 51% depending on design and follow-up. The two randomised trials, which are the most reliable, report 19.4% at six months and 22% at twelve. Higher figures generally come from surveys of seminar attendees rather than randomised comparisons.
Is Allen Carr better than nicotine patches or gum?
The trial that tested this compared the seminar against behavioural support combined with medication and found no clear difference. So: comparable, on current evidence, not better.
Does the book work as well as the seminar?
Unknown. Both randomised trials tested the live seminar with follow-up support, not the book alone. There's no equivalent trial of reading it by yourself.
Can you really quit without willpower?
The method's claim is that if you stop believing the cigarette gives you something, there's nothing left to resist. The evidence supports the approach working about as well as conventional support — which suggests the belief work is doing something real, not that quitting becomes effortless.
