There is less than two weeks to go until it is made illegal to smoke in a car when children are present.
Back in February MPs approved the regulations, which will enter into force on October 1.
In the run-up to next month, ex-smoker Pete Marland, leader of Milton Keynes Council, is encouraging smokers to give up for good.
He said: “The government passed this legislation to protect children from the dangers of smoke in the confined space of a car.
“Children who grow up around smokers are more likely to have breathing problems, get chest infections and have asthma, which as well as costing the NHS millions every year, ruins lives.
“However better than not smoking in a car, giving up for Stoptober can change your life, improve your health and save you money.
“The help is there if you need it and as an ex-smoker myself, it can be done.”
The change in law hopes to go a long way towards protecting vulnerable children from the effects of tobacco smoke exposure which can trigger asthma attacks and other respiratory disorders.
According to the British Lung Foundation around 430,000 children are exposed to second hand smoke in their family car every week.
A British Lung Foundation survey in 2011 found that 86% of children said that they wanted action to be taken to protect them from cigarette smoke when they are in the car.
