About No Smoking Day
No Smoking Day was first celebrated on Ash Wednesday 1984. It is an annual health awareness day that occurs the second Wednesday of March within the United Kingdom.
Smoking is the single greatest preventable cause of death in the world today. There are more than one billion smokers worldwide- and it kills up to half the people who smoke.
No matter how long you've smoked for, no matter how many cigarettes you smoke a day, your health will start to improve as soon as you quit.
Some health benefits are immediate, some are longer-term, but what matters is that it's never too late.
