Smoke-free living
It is never too late to stop. Your body starts to benefit within days.
Why it matters
Smoking is the leading cause of chronic lung disease. Stopping is the single most effective thing a smoker can do for their lungs, at any age.
What happens after you stop
Within days, carbon monoxide levels in the blood fall. Over the following weeks and months, many people notice that they cough less and find it easier to be active. The risk of serious disease keeps falling over the years.
Support that works
- Free stop-smoking services roughly triple your chances of quitting compared with willpower alone.
- Nicotine replacement and prescription medicines can ease cravings. Ask a doctor or pharmacist which is right for you.
- A plan: set a quit date, tell friends and family, and identify your triggers.
In the US you can call 1-800-QUIT-NOW for free help. Other countries have similar free services; see our resources page.
