Stopping smoking is one of the most effective things you can do to improve your health, but that does not mean it is easy. Nicotine dependence is powerful, smoking becomes tied to everyday routines, and withdrawal can make the first few weeks feel demanding.
You do not have to rely on willpower alone. NHS stop-smoking services, pharmacies and GP practices can provide practical support and help you choose treatments for cravings. Options now include nicotine replacement therapy, nicotine vapes and nicotine-free medicines such as varenicline and cytisine.
A previous unsuccessful attempt does not mean you cannot quit. Many people need several attempts, and each one can teach you something useful about your triggers, treatment needs and the situations in which you need more support.
This article provides general information and does not replace individual advice from a doctor, pharmacist, midwife or stop-smoking adviser.
Why is it so difficult to stop smoking?
Nicotine reaches the brain quickly and affects chemical pathways linked to reward, attention and mood. With regular smoking, the brain adapts to the presence of nicotine. When the nicotine level falls, withdrawal symptoms and cravings appear.
Smoking also becomes part of daily routines. You may associate cigarettes with:
- waking up or drinking coffee;
- taking a break from work;
- driving or waiting for transport;
- finishing a meal;
- drinking alcohol;
- socialising with other smokers;
- coping with boredom, anxiety or stress.
This means quitting involves both physical nicotine withdrawal and changing well-established habits. Stop-smoking treatment works best when it addresses both.
Nicotine is the substance that causes dependence, but it is not responsible for most of the disease caused by cigarettes. The greatest harm comes from inhaling smoke containing tar, carbon monoxide and many other toxic chemicals produced when tobacco burns.
This is why regulated nicotine replacement products can be used to help someone stop smoking. They provide nicotine without exposing the lungs to tobacco smoke.
What NHS help is available to quit smoking?
Local Stop Smoking Services offer free specialist support. Services may be provided through a council, NHS organisation, pharmacy, GP practice or community provider, depending on where you live.
A trained adviser can help you:
- make a realistic quit plan;
- choose an appropriate quit date;
- understand your smoking triggers;
- select nicotine replacement, vaping or medication;
- use stop-smoking products correctly;
- manage cravings and withdrawal;
- review progress and respond to setbacks.
Appointments may be available in person, by telephone or by video. Some services offer individual appointments, while others also provide group support.
NHS guidance says people using professional support are substantially more likely to stop successfully than those trying without help. The service is not there to lecture you or demand a perfect attempt. Advisers are used to helping people who feel uncertain, have tried before or are not yet sure which approach will suit them.
Finding a service in England
You can use the NHS tool to find a local Stop Smoking Service. It is sensible to contact the service before travelling because referral arrangements and appointment locations vary.
Other options include:
- asking a community pharmacist about stop-smoking support;
- asking your GP practice what is available locally;
- calling the National Smokefree Helpline for England on 0300 123 1044;
- using the free NHS Quit Smoking app;
- creating an online NHS Personal Quit Plan.
The National Smokefree Helpline is currently open Monday to Friday from 9am to 8pm and at weekends from 11am to 4pm. Opening times can change, so check the NHS website if you cannot get through.
Support in Scotland, Wales and Northern Ireland
Stop-smoking services are organised differently in each UK nation:
- Quit Your Way Scotland offers advice and links to local pharmacy and specialist services.
- Help Me Quit Wales provides free support, medication and a quit-smoking app.
- Northern Ireland stop-smoking information explains how to access local support through pharmacies and other services.
A pharmacist can be a convenient starting point if you do not want to wait for a GP appointment. Our guide to when to see a pharmacist instead of a GP explains the wider support pharmacies can provide.
How to make a quit plan
A quit plan turns a general intention into a set of practical decisions. It does not need to be elaborate, but it should cover your main triggers and what you will use instead of smoking.
Choose a quit date
Pick a date that gives you enough time to arrange treatment without allowing the plan to drift indefinitely. Avoid choosing a particularly stressful day if possible, but do not wait for life to become completely calm.
Some medicines are started before the quit date. A pharmacist, GP or adviser can explain the timing.
Notice when and why you smoke
For several days, note when you smoke and what was happening immediately beforehand. You may find that some cigarettes are driven mainly by nicotine withdrawal while others are strongly connected to habit, stress or social situations.
Useful questions include:
- Which cigarette would be hardest to give up?
- Do I smoke more with alcohol or particular people?
- Which situations make me reach for a cigarette automatically?
- What happened during previous quit attempts?
- Was my treatment strong enough and used for long enough?
Change the routine
Plan a specific alternative for predictable triggers. After a meal, you might immediately wash the dishes or go for a short walk. During a work break, move to a place where smoking is not allowed. Keep fast-acting nicotine replacement within reach rather than waiting until a craving becomes overwhelming.
Remove cigarettes, tobacco, lighters and ashtrays from your home, car and usual bags. Keeping an emergency cigarette often makes smoking more likely because it leaves the decision open during every craving.
Tell supportive people
Ask friends and family not to offer cigarettes or smoke around you during the early weeks. Explain whether you would prefer encouragement, distraction or some space when a craving arrives.
If you live with another smoker, quitting together may help, but your plan should not depend entirely on whether they remain smoke-free.
Nicotine withdrawal and cravings
Withdrawal can begin within hours of the last cigarette. Symptoms are usually strongest during the first week, particularly the first few days, and then gradually become easier. Some triggers and occasional cravings can continue for longer.
Possible withdrawal symptoms include:
- strong urges to smoke;
- irritability, restlessness or anxiety;
- difficulty concentrating;
- low mood;
- sleep disturbance or vivid dreams;
- headaches;
- increased appetite;
- constipation;
- coughing more for a short time.
A temporary increase in coughing can happen as mucus begins to clear and the airways recover. However, a persistent cough, coughing up blood, chest pain or worsening breathlessness should be medically assessed rather than assumed to be part of quitting. See our guide to coughs in adults and warning signs.
Handling an individual craving
Cravings rise and fall. They often feel as though they will continue indefinitely, but the most intense part commonly passes within a few minutes.
During a craving, try to:
- use your fast-acting nicotine replacement as directed;
- delay acting for a few minutes;
- change location or activity;
- drink water slowly;
- take several steady breaths;
- remind yourself why you chose to quit;
- contact someone supportive.
Keeping your hands or mouth occupied may help, but willpower strategies work better when withdrawal is also being treated properly.
Nicotine replacement therapy
Nicotine replacement therapy, or NRT, provides nicotine without the tar, carbon monoxide and other toxic substances in cigarette smoke. It reduces withdrawal and makes cravings easier to manage.
NRT is available as:
- skin patches;
- chewing gum;
- lozenges or small tablets;
- mouth spray;
- nasal spray;
- an inhalator;
- oral strips.
You can buy NRT from pharmacies, supermarkets and other retailers. It may also be provided or prescribed through a stop-smoking service, pharmacy or GP practice. Whether a product is free, subsidised or subject to a prescription charge depends on the service and where you live.
Combining slow-acting and fast-acting NRT
A common and effective approach is to use a patch for steady nicotine delivery alongside a fast-acting product for sudden cravings.
For example, a patch may control background withdrawal throughout the day, while gum, lozenges or mouth spray can be used when a strong urge appears. Using both is often more effective than relying on one product.
Many unsuccessful NRT attempts happen because the dose was too low, the product was used inconsistently or treatment was stopped too soon. NHS guidance generally recommends using stop-smoking products for around 12 weeks or for as long as they are needed to prevent a return to smoking.
A pharmacist or adviser can help if you are unsure about strength, side effects or technique. Gum, for example, is not used in exactly the same way as ordinary chewing gum.
Is nicotine replacement safe?
For most adults who smoke, NRT is much safer than continuing to smoke. People who are pregnant or have particular medical concerns should discuss the most suitable product with a pharmacist, GP, midwife or stop-smoking adviser.
Nicotine pouches are not licensed in the UK as stop-smoking treatments. Their longer-term safety and effectiveness for quitting are less well established than licensed NRT.
You can read more in the NHS guide to nicotine replacement therapy.
Prescription and nicotine-free medicines
Medicines that do not contain nicotine can reduce cravings, ease withdrawal or make smoking less rewarding. They are not suitable for everyone and require an assessment of medical history, other medicines and possible side effects.
Varenicline
Varenicline is available again in the UK after a period when supplies were disrupted. It works on nicotine receptors in the brain, reducing cravings and making cigarettes less satisfying if someone smokes.
Treatment usually begins before the planned quit date. Possible side effects include nausea, sleep disturbance, unusual dreams, headache and digestive symptoms.
Tell the prescriber about kidney problems, pregnancy, breastfeeding and any significant changes in mood. Do not share the medicine with another person.
Cytisine or cytisinicline
Cytisine—also referred to as cytisinicline in NICE guidance and medicine information—is a newer option in the UK, although it has been used in some other countries for many years.
It acts on similar nicotine pathways to varenicline, helping reduce cravings and the rewarding effect of smoking. Treatment follows a specific dosing schedule and should be used exactly as directed.
Possible side effects include nausea, sleep problems, dry mouth, headache and digestive symptoms. A prescriber or pharmacist will check whether it is suitable alongside your other medicines and health conditions.
Bupropion
Bupropion, also known by the brand name Zyban, changes the activity of certain chemical messengers in the brain and can reduce withdrawal symptoms.
It is not suitable for everyone, including some people with a history of seizures or particular eating disorders. It can also interact with other medicines, so a proper prescribing assessment is essential.
Combining treatments
Current NHS guidance encourages discussing combinations rather than assuming one product must be used alone. For some people, a nicotine-free medicine combined with NRT or a nicotine vape offers the strongest support.
The appropriate combination depends on the medicine, medical history, pregnancy status and individual preference. Ask a stop-smoking adviser, pharmacist or GP rather than combining prescription treatments independently.
Can vaping help you stop smoking?
A nicotine vape can help an adult smoker stop because it provides nicotine without burning tobacco. It also replaces some of the hand-to-mouth routine and inhalation pattern associated with cigarettes.
Vaping is not completely harmless, and its long-term effects continue to be studied. However, the NHS considers it substantially less harmful than smoking. The central comparison for an adult smoker is between vaping and continuing to inhale tobacco smoke—not between vaping and breathing clean air.
For the greatest health benefit, switch completely rather than continuing to smoke regularly alongside vaping. Even a small number of cigarettes still exposes you to toxic smoke.
Choose a nicotine strength that controls cravings. If the vape is too weak or used too infrequently, cigarettes may remain more satisfying and relapse becomes more likely. A stop-smoking adviser can support you even if you buy your own device.
Some local areas participate in schemes that provide eligible adult smokers with a free vape starter kit and behavioural support. Availability and criteria differ, so check with your local service.
Vaping is intended here as a quitting tool for adults who smoke. Children, young people and people who do not smoke should not start vaping. Our separate guide to vaping health effects will explore the risks in more detail.
Do you have to stop vaping immediately?
The first priority is to stop smoking and remain smoke-free. Do not rush to stop vaping if doing so is likely to send you back to cigarettes.
Once you feel secure in not smoking, you can consider gradually reducing nicotine strength or vaping frequency. Some people need to vape for longer than others. A slower reduction is generally preferable to returning to tobacco.
Quitting during pregnancy and with health conditions
Pregnancy and breastfeeding
Stopping smoking at any point in pregnancy benefits both the pregnant person and the baby. It reduces exposure to carbon monoxide and lowers the risks of complications, stillbirth, premature birth and low birth weight.
NRT can be used during pregnancy when it is needed to support quitting, but speak to a midwife, pharmacist, GP or specialist adviser about product choice. Varenicline and bupropion are not recommended during pregnancy, and varenicline is not usually recommended while breastfeeding.
If vaping is what enables a pregnant person to stop smoking, the NHS advises that it is much safer than continuing to smoke. Licensed NRT is generally the preferred first option because more is known about it and it can be prescribed.
Do not avoid asking for help because you feel embarrassed about continuing to smoke. Maternity stop-smoking services are designed to provide support rather than blame.
Heart and lung conditions
Stopping smoking is especially valuable for people with asthma, COPD, heart disease or cardiovascular risk. A clinician or pharmacist can help choose a suitable treatment if you have concerns about medication or nicotine.
People with COPD may notice changes in cough and mucus as they stop. Quitting cannot reverse all existing lung damage, but it can slow further decline and reduce future risk. See our guide to COPD symptoms and treatment.
Smoking also increases the likelihood of heart attack and stroke. Our guide to reducing heart attack and stroke risk covers other important steps.
Mental health
Some people smoke to manage anxiety, low mood, trauma symptoms or the side effects of mental health medication. Nicotine may seem calming because a cigarette temporarily relieves withdrawal that has developed since the previous cigarette.
Withdrawal can temporarily increase irritability or anxiety, but after this early period, stopping smoking is generally associated with improved mood and reduced stress compared with continuing to smoke.
If you use medication for a mental health condition, tell the prescriber when you stop smoking. Tobacco smoke—not nicotine itself—changes how the body processes some medicines. Doses may need monitoring or adjustment after quitting.
Ask for additional support if low mood becomes severe or you develop thoughts of self-harm. Our guide to accessing mental health services in the UK explains routine and urgent routes.
What if you smoke after your quit date?
Smoking one cigarette does not have to become a complete return to smoking. A lapse is useful information: it shows where the quit plan needs strengthening.
If you smoke:
- stop again as soon as possible rather than waiting for another date;
- continue using your stop-smoking treatment unless advised otherwise;
- remove any remaining cigarettes;
- identify what triggered the lapse;
- contact your adviser or pharmacist;
- adjust the plan for the same situation next time.
Try to avoid the thought that you have “ruined” the attempt. The health benefit comes from what you do next, not from maintaining a perfect record.
If you have repeatedly relapsed while using the same method, consider changing treatment. You may need stronger nicotine replacement, a combination of products, a prescription medicine or more frequent behavioural support.
Cutting down before quitting
Stopping completely gives the greatest health benefit, but some people prefer to reduce gradually before a planned quit date. NRT can sometimes support this approach.
Cutting down without a plan may not reduce harm as much as expected because people can compensate by inhaling more deeply from each cigarette. Agree a clear route towards stopping rather than allowing gradual reduction to continue indefinitely.
What happens to your body after quitting?
Recovery begins soon after the last cigarette. According to NHS guidance:
- After around 20 minutes: your pulse begins returning towards normal.
- After eight hours: carbon monoxide in the blood has fallen substantially and oxygen levels are recovering.
- After 48 hours: carbon monoxide has fallen to a non-smoker level, the lungs begin clearing mucus and taste and smell improve.
- After 72 hours: bronchial tubes begin to relax and breathing may feel easier.
- After two to 12 weeks: circulation improves.
- After three to nine months: cough, wheezing and breathing problems often improve as lung function recovers.
- After one year: the risk of heart attack is around half that of someone who continues to smoke.
- After 10 years: the risk of dying from lung cancer is around half that of a continuing smoker.
These are broad averages rather than deadlines. Some people cough more temporarily, and those with an existing condition may recover differently.
Quitting also reduces the effect of second-hand smoke on children, partners and other people around you. Homes and cars become easier to keep free from smoke, and the financial savings begin immediately.
You can explore the current timeline in the NHS guide to what happens after quitting.
Frequently asked questions about quitting smoking
What is the most effective way to stop smoking?
Combining behavioural support with an effective stop-smoking product gives a better chance than relying on willpower alone. Depending on the person, this might involve combination NRT, a nicotine vape, a nicotine-free medicine or an approved combination.
Can I get nicotine patches free from the NHS?
Local Stop Smoking Services may provide free or subsidised NRT, vapes or medication. What is offered varies by area. Prescribed items may be subject to the usual prescription-charge rules unless you qualify for free prescriptions.
Is nicotine replacement safer than smoking?
Yes. NRT provides nicotine without the tar, carbon monoxide and many toxic chemicals created by burning tobacco. For most smokers, it is much safer than continuing to smoke.
Can I use a patch and nicotine gum together?
Yes, this is a common approach. The patch provides steady nicotine while gum or another fast-acting product deals with sudden cravings. Ask a pharmacist or adviser about suitable strengths and correct use.
Is vaping better than nicotine patches?
Both can be effective. Some people prefer the familiar physical routine of vaping, while others prefer licensed NRT. The best option is one that controls cravings, is suitable for your health and helps you stop smoking completely.
Is vaping completely safe?
No. Vaping is not risk-free, but the NHS considers it much less harmful than smoking. It is recommended as a quitting option for adult smokers, not for children or people who do not smoke.
Will I gain weight when I stop smoking?
Some people gain some weight because nicotine affects appetite and metabolism, and food may temporarily replace the hand-to-mouth habit. The health benefits of quitting are much greater than the risks of modest weight gain. Regular meals, activity appropriate to your health and non-food responses to cravings may help.
How long do nicotine cravings last?
An individual craving often peaks and passes within several minutes, although cravings can return frequently during the first days. They generally become less intense and less frequent over the following weeks.
How long should I use stop-smoking products?
NHS guidance commonly recommends at least 12 weeks, and longer if needed to prevent relapse. Do not stop treatment simply because a few days have gone well.
Can I stop smoking if everyone around me smokes?
Yes, but you may need stronger boundaries and more support. Ask people not to offer cigarettes or smoke around you, avoid high-risk situations initially and keep treatment available when social triggers cannot be avoided.
Is it worth quitting after many years?
Yes. Stopping benefits health at any age and after any length of smoking. It reduces future risks and can improve circulation, breathing and response to medical treatment.
What should I do first?
Contact your local Stop Smoking Service, a pharmacist or your GP practice. Discuss previous attempts, choose a treatment and set a realistic quit date. You do not need to wait until you feel completely confident before asking for help.
