The smoking ban helped many smokers give up the habit, a survey has revealed.
Some 37% of ex-smokers believe that the ban, which applies to public areas including pubs, restaurants and train stations, helped them give up tobacco.
That said, the survey, which was carried out by Pfizer, went on to reveal that Britain is still home to approximately 10 million smokers, with a quarter of these people admitting that they are happy to go outside for a cigarette - even if the weather is extremely unsavoury.
The survey of 6,300 people discovered that a fifth of smokers have sought medical assistance in trying to give up.
It was conducted to celebrate the fifth anniversary of the implementation of the smoking ban. It came into effect in July 2007.
Prior to then, smokers could light up in public places, including bars and clubs. The ban was brought in to protect the health of other patrons and staff members as second-hand smoke is deemed to be every bit as dangerous as first-hand smoke.
