The best way to quit smoking: what the evidence says.

Updated 29 September 20264 min readBy the UrgeLock team

There is no single trick, but the research is clear on what improves your odds: an aid, plus support, plus a plan for the hard minutes.

The short version
  • The best-evidenced route is a stop-smoking aid and behavioural support together, not willpower alone.
  • In a large Cochrane analysis, about 14 in 100 people using varenicline, cytisine or nicotine e-cigarettes quit long-term, against about 6 in 100 with no aid.
  • Using two forms of nicotine replacement at once (a patch plus gum, lozenge or spray) worked nearly as well, around 12 in 100. One form alone was around 9 in 100.
  • Behavioural support makes every one of these work better.

What works best

Cochrane, an independent group that reviews the research, analysed data on over 150,000 smokers (2023). Its findings, in plain terms:

  • Nicotine e-cigarettes, varenicline and cytisine helped the most people quit, roughly 14 in 100 long-term compared with about 6 in 100 using no aid.
  • Combination nicotine replacement (patch plus a fast-acting form) was nearly as effective, about 12 in 100. A single form, such as a patch alone, was lower, about 9 in 100.
  • Behavioural support matters. The review says these aids "work better when people are also receiving behavioural support to quit."

Availability differs by country. Varenicline has had shortages in several regions, and cytisine is not licensed in most countries outside central and Eastern Europe. For most people, combination nicotine replacement is the most accessible highly effective option. A doctor or pharmacist can tell you what is available and safe for you.

A simple plan

1. Decide why

Write your reasons: health, money, family, freedom. Put them where you will see them.

2. Set a quit date

Pick a date within a week or two, near enough to keep momentum and far enough to prepare. If you prefer to cut down first, still choose the day you stop completely. Avoid a stressful stretch.

3. Choose your aid

Talk to a doctor, pharmacist or stop-smoking service about nicotine replacement or other medicines. Ask about using two forms of nicotine replacement together.

4. Line up support

Support can be a free quitline, a text-message programme, a friend who knows your date, or a stop-smoking service. Call the quitline for your country: it is free and confidential.

Free, confidential helpUnited States: call 1-800-QUIT-NOW (1-800-784-8669). India: the National Tobacco Quitline, 1800-11-2356 (quittobacco.in). United Kingdom: NHS quit smoking support. Ireland: HSE quit smoking.

5. Plan for the hard minutes

Most slips happen in one tough minute: after a meal, under stress, with a coffee, when others light up. Learn your triggers and have a five-minute plan for each. Our guides to common triggers and stopping a craving show how.

6. Expect withdrawal, and do not let one slip restart everything

Symptoms are usually strongest in the first week and ease from there. See our withdrawal timeline. If you slip, note what set it off and go back to your plan.

Where UrgeLock fits

UrgeLock is the "support in your pocket" part of the plan, not a replacement for medicines or a quitline. Log for a day and it shows your triggers and riskiest hours; then it shows when your next urge is likely, and when one hits, one tap gives a guided action matched to the moment. You can pick your own quit day in the app, and from that day it becomes a smoke-free timer with a recovery timeline.

Common questions

Is it better to quit cold turkey or cut down?

Either can work, but most people do better with preparation, an aid and support than with willpower alone. If you cut down first, set a real quit date so cutting down has an end.

What is the most effective stop-smoking aid?

Cochrane found nicotine e-cigarettes, varenicline and cytisine helped the most people quit, followed by combination nicotine replacement. Which one is right depends on your health and where you live, so ask a doctor or pharmacist.

Does quitting with an app work?

Text-message programmes have good evidence behind them. For smartphone apps, a Cochrane review found no clear evidence of a benefit on their own, so treat an app as one part of a plan alongside support and, if you want them, medicines.

How many times do people try before quitting?

Many people need more than one attempt. Each attempt teaches you what your triggers are, so keep the notes and try again with a stronger plan.
