How to Quit Smoking
Evidence-based guides to quitting smoking: picking a quit date, managing cravings, getting through the first week, and handling a slip. No lectures.
Quitting smoking is hard, and not because of a lack of willpower: regular nicotine changes how the brain's reward and receptor systems work, and years of smoking tie cigarettes to your daily routines. Knowing how that works makes the process easier to plan for.
These articles cover the practical side: what to expect day by day, which strategies actually reduce cravings, how to handle the urge that hits at exactly the wrong moment, and what to do when you slip. No moralizing about why you should quit — you already know. This is about how.
What the research says about quitting
Most people who quit for good don't do it on the first try, and many take more attempts than the numbers usually quoted: a Canadian cohort study estimated about 30 attempts on average before a year off cigarettes, though many people need far fewer. Every attempt is practice at spotting your own triggers.
Going it alone is the hardest route: a review of studies of people quitting with no help found that only about 3–5% were still off cigarettes 6 to 12 months later. Support changes the odds. In Cochrane reviews, nicotine replacement therapy (NRT) raised quit rates by about 50–60%, combining a patch with a fast-acting form worked better than one form alone, and varenicline more than doubled quit rates against placebo. Free help from a local stop smoking service combines medicines with support.
The first week
The NHS says withdrawal is usually strongest in the first week, especially the first 3 days: nicotine clears from your system, receptors that adapted to it take time to settle, and cravings are most intense. Physically, you may experience irritability, difficulty concentrating, increased appetite, headaches, and disrupted sleep. This is your nervous system recalibrating — not evidence that you can't do it.
Symptoms then ease, and the NHS says they last three to four weeks on average. What lasts longer is the habit layer: the cigarette tied to coffee, the after-meal smoke, the stress response you've practised for years. Behavioural support works on this layer, and it adds to the effect of medicines.
Cravings
The NHS says a craving usually lasts only a few minutes, and up to 15 minutes at most, and it passes whether you smoke or not. Knowing this — and having a plan for those minutes — changes the dynamic. The 4 D's (Delay, Drink water, Deep breathe, Do something else) are simple enough to remember under stress. Apps, gum, or a short walk can all bridge the gap.
Over time, cravings come less often. As withdrawal passes, the ones that remain tend to be set off by particular places, people and moods rather than being constant background noise.
Medication and NRT
Nicotine replacement therapy — patches, gum, lozenges, inhalers — reduces withdrawal by providing a controlled, slower nicotine dose without the more than 7,000 chemicals in tobacco smoke. If you are pregnant or have a heart condition, ask a pharmacist or GP which product suits you. It's a bridge, not a forever solution.
Prescription options — varenicline (formerly sold as Champix) and bupropion — work through different mechanisms. Varenicline partly activates nicotine receptors while blunting the reward from smoking. Both raise quit rates against placebo, and in the Cochrane review varenicline helped more people quit than bupropion or a single form of NRT. Neither is recommended by the NHS in pregnancy.
