No Smoking Day is one of the UK's biggest annual health awareness campaigns. Every year over a million smokers will use No Smoking Day to try to quit.
No Smoking Day always falls on the 2nd Wednesday of every March.
Stopping smoking might be one of the hardest things you’ll ever do but it is also one of the best – and you don’t have to face the battle alone.
There's lots of free support on offer and by using the support that's right for you, you'll be boosting your chance of quitting for good.
Why quit?
Everybody has their own personal reason for wanting to give up smoking.
Some people give up as part of a larger lifestyle change - to be healthier, to get fit, or to save money.
For some, it’s more about how their smoking affects the people around them – their family, friends, and little ones.
Whatever your reason, thinking carefully about your motivation and keeping a reminder in key places can be really helpful for keeping you going through the tough times.
Financial benefits
Quitting smoking doesn’t have to be about losing something - it's about getting something back too.
Currently a packet of 20 cigarettes costs around £8, so quitting will give a 20-a-day smoker an extra £56 a week.
You'll also save money in other ways. Life, home and car insurance can all be cheaper when you’re a non-smoker.
What’s in a cigarette?
Each cigarette contains around 4,000 chemicals, as well as nicotine, many of which are known to be toxic.
Here are a few of the nasties you'll be inhaling in every drag:
- Acetone widely used as a solvent, for example in nail polish remover
- Ammonia found in cleaning fluids
- Arsenic a deadly poison, used in insecticides
- Benzene used as a solvent in fuel and chemical production
- Cadmium a highly poisonous metal used in batteries
- Carbon monoxide (CO) an odourless, tasteless and poisonous gas; makes breathing more difficult as it combines with the blood that carries oxygen around the body. Up to 15 per cent of a smoker's blood may be carrying CO instead of oxygen, making the heart work harder, and potentially leading to coronary heart disease and circulation problems.
- Cyanide a deadly poison
- Formaldehyde used to preserve dead bodies
- Shellac becomes a wood varnish when mixed with a form of alcohol
- Tar a mixture of chemicals (including formaldehyde, arsenic and cyanide). About 70 per cent of the tar is left in smokers' lungs, causing a range of serious lung conditions
So, how about trying to give up smoking just for one day? You may find that it's not as hard as you though it might be 
Quit smoking 17 days.
