When to see a doctor
See a doctor urgently if:
- If you have chest pain, severe shortness of breath, or are coughing up blood
Book a routine appointment if:
- If you want to quit smoking, talk to your healthcare provider. They can give you advice and refer you to support services.
- If you have a cough that does not get better after a few weeks
- If you notice changes in your voice or find it hard to swallow
Diagnosis
Smoking cessation itself is not a diagnosis, but your healthcare provider may ask you about your smoking history and how many cigarettes you smoke each day. They may also check your lungs and overall health.
Tests that may be done
- A carbon monoxide breath test to see how much smoke you are exposed to
- Lung function tests if you have symptoms like shortness of breath
- A medical history and physical exam
What to expect at your appointment
Your healthcare provider will have a friendly conversation about your smoking and your desire to quit. They may ask about your past attempts and offer support options tailored to you.
Treatment
Treatment for smoking cessation involves a combination of support, behavioral changes, and sometimes medicines to help with withdrawal and cravings. The goal is to help you quit for good.
Self-care at home
- Set a quit date and tell friends and family so they can support you
- Remove all cigarettes, ashtrays, and lighters from your home and car
- Find healthy ways to handle stress, such as walking, deep breathing, or calling a friend
- Avoid situations where you usually smoke, like bars or coffee breaks with smokers
Medical treatments
Medical treatments for smoking cessation include nicotine replacement therapies (like patches, gum, or lozenges) and non-nicotine prescription medicines that help reduce cravings and withdrawal symptoms. Your healthcare provider can help you choose what is right for you. Always follow their advice and never take more than the recommended dose.
When is surgery considered?
If you need surgery, quitting smoking before the operation can improve your recovery and reduce the risk of complications. Talk to your surgeon or healthcare team about a plan to quit.
Living with this condition
Living smoke-free means building new habits. Keep your hands and mind busy with activities like knitting, drawing, or playing games. Drink plenty of water and chew sugar-free gum when you feel a craving.
Lifestyle tips
- Avoid alcohol and other triggers that make you want to smoke
- Exercise regularly – even a short walk helps reduce cravings
- Get enough sleep to help manage stress
- Reward yourself for milestones like one week or one month smoke-free
Diet and exercise
Eating a balanced diet with fruits, vegetables, and whole grains can help manage weight gain that sometimes happens when quitting. Light to moderate exercise, such as walking or cycling for 30 minutes most days, improves mood and reduces cravings.
Mental health and emotional wellbeing
Quitting smoking can be emotionally challenging. You may feel irritable, anxious, or down. These feelings are normal and usually get better within a few weeks. If you have thoughts of harming yourself, please reach out to a crisis helpline immediately.
Prevention
The best way to prevent smoking addiction is to never start smoking. If you have already started, quitting as early as possible reduces the harm. Many people who start smoking as teenagers later regret it.
Vaccines
There is no vaccine that prevents smoking addiction. However, staying up to date with vaccines like the flu shot and pneumonia vaccine is important for people who have smoked, because their lungs are more vulnerable to infections.
Screening programmes
Routine screening for tobacco use is often done by healthcare providers during checkups. If you smoke, they will ask about it and offer help to quit.
Complications
If left untreated
- Lung cancer and other cancers of the mouth, throat, bladder, and pancreas
- Chronic obstructive pulmonary disease (COPD) – a long-term lung condition that makes breathing hard
- Heart disease, stroke, and high blood pressure
- Early death
Long-term outlook
The good news is that it is never too late to quit. Within hours of stopping, your body begins to heal. Your risk of cancer, heart disease, and many other problems goes down over time. Many people who quit smoking live longer and healthier lives. Every attempt to quit brings you closer to success.
