Donna Nicholson says she quit smoking because of the effects passive smoke could have on her children's health.
Fresh, the North East's regional office dedicated to tackling smoking, have welcomed the Government's latest campaign against passive smoking.
Director Ailsa Rutter said: "Smoking at the back door or winding down the window a little bit in your car just isn't enough to protect children from the really damaging effects of breathing in second-hand smoke.
"Eighty-five percent of second-hand smoke is invisible. It's odourless, it lingers for up to three hours and you really need very fast flowing air for it to come out of the car window."
New figures show that 13,000 children in the North East were admitted to hospital with smoking related problems last year.
The news comes as the Government launches its latest anti-smoking campaign warning people of the dangers of passive smoking.
TV and online adverts in England will outline the risk to children of people lighting up in cars and homes.
Today is No Smoking Day and health experts are encouraging people to quit by highlighting the cost of cigarettes.
The anti-smoking charity FRESH says the average smoker would save £2500 a year by giving up.

Events are taking place across the North East to mark No Smoking Day.
It is the 30th year that the day has been held and aims to help people stop smoking.
One of those who has been persuaded to stop is Derek Athey from Darlington.
He has put the hundreds of pounds he saved on cigarettes towards helping him pass his HGV licence and quit the habit a year ago when he was diagnosed with arterial disease in his legs, caused by his smoking.
The Northumberland Stop Smoking Service has warned that there are still many older smokers in the region putting their lives at risk, years after the smoking ban was introduced.
The warning comes as the Government released a hard-hitting advert which shows a tumour growing out of a cigarette.
The North East has seen the fastest rate of people quitting, but the service says more people need to follow suit.
Bob Cunningham and his family has had their first smokefree Christmas in more than 20 years after he gave up the habit.
He said that he is now fitter, can taste sugar and salt better, and has hundreds more pounds to spend on his family.
He is one of more than 5,000 people who have benefited from NHS Northumbria Healthcare's Stop Smoking services.
NHS Northumberland says smokers are four-times more likely to give up smoking if they access one of their free services.
It comes as the Government releases a new hard-hitting advert to deter people from smoking. The advert shows a smoker's cigarette growing a tumour.
A campaign to rid Middlesbrough of discarded cigarette litter will be launched in the town later today.
The initiative follows a string of complaints from residents to Cllr Habib Rehman who has said he wants to appeal to members of the public to consider other residents and the environment, and to dispose of their waste responsibly.
The campaign will be launched at Teesside University with Streetscene staff who will distribute cigarette stub pouches to students.
The team will also offer information and advice on the environmental effects of dropping cigarette litter, and the following day leaflets will be distributed in the ward on smoking-related environmental and health issues.
