The Better Health Smoke Free initiative highlights research showing the impact adult smokers have on younger people.

Some 4.9% of young teenagers who grow up with a smoking caregiver also smoke regularly, against just 1.2% for those whose caregiver doesn't smoke.

The NHS has released a film as part of the campaign showing health experts discussing the link between adults smoking and the chances of their children starting.

It shows a family GP, a child psychologist and smoking cessation experts Professor Nick Hopkinson and Dr Anthony Laverty from Imperial College London urging parents to quit for their new year resolution.

It's hoped the research on the link between children and adults smoking will give people extra willpower, said health minister Maggie Throup.

She said: "We know that many people make a quit attempt in January, and while there are so many good reasons to stop smoking for yourself, we hope that this new campaign - by highlighting the inter-generational smoking link with parents influencing their children - will be the added motivation many need to ditch the cigarettes for good this year.

"With so much help and support available for parents, carers and anyone looking to quit - including the NHS Quit Smoking app, support on Facebook, daily emails and texts, and an online Personal Quit Plan - you won't be alone in your new year's resolution."

The NHS gives the following tips for a smoker who has named their quit date:

• List your reasons to quit
• Tell people you're quitting
• If you have tried to quit before, remember what worked
• Use stop smoking aids
• Have a plan if you are tempted to smoke
• List your smoking triggers and how to avoid them
• Keep cravings at bay by keeping busy
• Exercise away the urge
• Join the Facebook group for support and advice
