Smoking Cessation

Quitting smoking can support your health in both the short term and the long term. Some changes may begin soon after stopping, while other benefits build gradually.

Changes can begin quickly after quitting. Pulse rate may start returning to normal after around 20 minutes, oxygen levels begin recovering after around 8 hours, and after 48 hours the lungs start clearing mucus while taste and smell may improve. Over the following weeks and months, circulation and lung function may also improve.

Smoking cessation may help to:

• reduce exposure to harmful substances in tobacco smoke;
• support breathing and circulation over time;
• reduce harm linked to second-hand smoke;
• support better long-term health;
• lower some smoking-related health risks over time.

Quitting does not mean every risk disappears immediately. But it can be an important step toward protecting your health.

Smoking is not only a habit. For many people, it is also linked to nicotine dependence.

Nicotine affects the brain’s reward system, and both the chemical addiction and the habits built around smoking can make quitting difficult. This is why stopping smoking is often not just a question of willpower.

Smoking can become connected to everyday moments such as:

• drinking coffee;
• taking a break;
• feeling stressed;
• driving;
• socialising;
• finishing a meal;
• trying to relax.

Because of this, people may want to quit tobacco but still find themselves reaching for a cigarette in familiar situations.

There is no single quit method that works for everyone. The right approach can depend on your smoking habits, your health, your triggers, and the support available to you.

Support for smoking cessation may include:

• a quit plan;
• support from a healthcare professional;
• counselling or behavioural support;
• nicotine replacement therapy;
• medication, when appropriate;
• help with cravings and triggers;
• support from friends, family, or community services.

Smoking cessation care can include screening, assessment, treatment, tools, and support resources for people who are trying to quit. Patients who smoke should be encouraged to quit and offered support during healthcare encounters.

For many people, quitting may feel more manageable when they are not trying to do it completely alone.

What is the best way to stop smoking?
There is no single method that works for everyone. A quit plan, healthcare support, counselling, nicotine replacement therapy, medication when appropriate, and support from others may all help.

Can nicotine replacement therapy help with quitting smoking?
Nicotine replacement therapy may help some people manage cravings while they work toward stopping smoking. It is best to discuss the right option with a healthcare professional.

Is quitting smoking only about willpower?
No. Smoking is often linked to nicotine dependence, daily routines, stress, and habits. Support and planning can make quitting feel more manageable.

What should I do when I get a craving?
It may help to wait a few minutes, move away from the trigger, drink water, take a short walk, do something with your hands, or contact someone supportive.

Cravings can be one of the hardest parts of stopping smoking. They can feel strong, especially when they are linked to daily routines or emotional triggers.

Nicotine cravings can be strong but often ease within minutes. It is recommended to know your triggers, make a plan, distract yourself when a craving appears, and remind yourself why you want to stop smoking.

When cravings appear, it may help to:

• wait a few minutes before acting on the urge;
• move away from the trigger;
• do something with your hands;
• take a short walk;
• drink water;
• contact someone supportive;
• remind yourself why quitting matters to you.

A craving does not mean you have failed. It is often part of the process.

Many people want to know what happens to the body after quitting smoking. The answer can vary from person to person, but some changes may begin earlier than people expect.

There are several possible changes after quitting, including improved oxygen levels, lower carbon monoxide levels, easier breathing after a few days, improved circulation after 2 to 12 weeks, and improved cough, wheezing, or breathing problems after 3 to 9 months.

Some short-term changes may include:

• cravings;
• mood changes;
• sleep changes;
• coughing or throat irritation;
• changes in appetite;
• tiredness or low energy.

Some longer-term changes may include:

• improved circulation;
• better breathing over time;
• improved lung function;
• lower risk of some smoking-related health problems;
• more confidence in staying smoke-free.

These changes do not happen in the same way for everyone. But they can help show why quitting is still worth taking seriously.

A quit plan gives you something practical to follow. It can help you prepare for cravings, avoid common triggers, and decide what kind of support you may need.

A quit plan may include:

• why you want to quit;
• your quit date;
• your strongest smoking triggers;
• what you will do when cravings appear;
• who you can ask for support;
• whether you want to discuss medication or nicotine replacement therapy;
• how you will respond if you smoke again.

A slip does not have to mean the whole process has failed. Many people need more than one attempt before they stop smoking for good.

Smoking is strongly linked to lung cancer risk, which is why smoking history is often discussed in relation to lung health and screening.

The National Cancer Institute explains that lung cancer screening can be an important opportunity to offer smoking cessation support. In one clinical trial involving people undergoing lung cancer screening, a programme combining intensive counselling and cessation medications helped more people quit than referral to a quitline alone.

This does not mean the same approach is right for everyone. But it shows why support around quitting can be especially important for people with lung health concerns or a history of smoking.

You may want to speak with a healthcare professional if:

• you smoke and are worried about your lung health;
• you have tried to quit before and found it difficult;
• cravings feel hard to manage;
• you are unsure whether nicotine replacement therapy is right for you;
• you are considering medication to help you quit;
• you have symptoms that worry you;
• you have questions about lung cancer screening.

Getting support early can make the next steps clearer.

Smoking cessation can feel like a big goal, but it often begins with small steps.

That may mean:

• delaying the first cigarette of the day;
• noticing your strongest triggers;
• replacing one smoking routine;
• setting a quit date;
• asking someone for support;
• speaking with a healthcare professional;
• tracking cravings and symptoms.

Small steps do not make the goal less serious. They can make it more realistic.

Smoking addiction can feel frustrating. Some people feel guilty, ashamed, or discouraged if they have tried to quit before.

But quitting smoking is not a character test. It is a health decision that may need planning, support, and time.

Smoking cessation can help you reduce exposure to tobacco, support your health over time, and feel more in control of your daily habits. The most important next step is not to do it perfectly. It is to keep moving toward support that helps you stay smoke-free.
