How to quit smoking: the plan with the best odds

Most people try to quit smoking on willpower alone, and most of those attempts don't last. That's not a character flaw. Nicotine is built to win against willpower. The good news: there's a combination that gives you much better odds, and it's free or cheap in most countries. Here's the plan.

The combination that works best

The strongest evidence is for two things together:

1. Support: a stop-smoking service, even a few short calls or sessions.
2. Something to take the edge off nicotine withdrawal: nicotine replacement, a prescribed stop-smoking medicine, or for many smokers, a vape.

In the UK, the NHS says people who use a stop-smoking service together with medication are up to three times more likely to quit than those going it alone. Services exist almost everywhere: Tabac Info Service 39 89 in France, your local NHS Stop Smoking Service in the UK, 1-800-QUIT-NOW in the US.

Step 1: Score how hooked you are

Two questions, known as the Heaviness of Smoking Index:

Cigarettes a day	Score	First cigarette after waking	Score
10 or fewer	0	After 60 minutes	0
11 to 20	1	31 to 60 minutes	1
21 to 30	2	6 to 30 minutes	2
31 or more	3	Within 5 minutes	3

Add them up. 0 to 1 is low dependence. 2 to 4 is moderate: nicotine replacement is strongly worth it. 5 to 6 is high: ask a pharmacist or the service about combining a patch with a fast-acting form like gum, a lozenge or a spray. They'll set the strength for you.

Step 2: Set a quit date, and stop on it

Pick a day within the next two weeks, ideally not your most stressful one. Cutting down first only helps if it has an end date. On the date, you stop completely. The night before, throw out every cigarette, lighter and ashtray, at home, in the car and in your bag.

Step 3: Map your automatic cigarettes

Most smokers have five or six cigarettes they don't really decide to have: first coffee, after meals, the drive, work breaks, with a drink, before bed. Write each one down with a replacement you can start in under two minutes:

• Coffee: switch to tea for the first two weeks, or drink it somewhere you never smoked.
• After meals: get up, brush your teeth, go for a short walk.
• Work breaks: take them, but with a colleague who doesn't smoke, or a walk round the block.
• Drinks: go out less for the first month, or hold a drink in your smoking hand.

Step 4: Get through the cravings

A craving usually peaks and passes within a few minutes. Give each one 15 minutes: stand up, cold water, move, use your fast-acting nicotine replacement if you have one. Irritability, restlessness, poor concentration and hunger are normal in the first weeks and usually ease over about a month.

Some weight gain is common. It's far less harmful than smoking, and you can deal with it once the cigarettes are gone.

Step 5: Count the money

A pack a day at EUR 12 is about EUR 4,380 a year. Work out your own number and pick something to spend a month's worth on at the end of week four.

If you slip

One cigarette isn't a relapse, but it's the start of one if you let it be. Ask what happened just before, change one thing, and get straight back on your plan. Don't buy a pack "to finish it".

Vaping as a way out

Vaping is much less harmful than smoking and many people use it to quit. If you go that way, switch completely rather than doing both, and plan to come off nicotine later. Our guide to quitting vaping covers that next step.

If you're pregnant, talk to your midwife or doctor: there's dedicated support, and it's never too late in a pregnancy to stop.
