Almost 44,000 people used a government-funded stop-smoking service during the past year.
The Quit Group, a charitable trust set up to run quit smoking programmes, said it was thrilled with the record number of people coming to the trust to stop smoking.
Executive director Helen Glasgow said quitting smoking not only had immediate health benefits, it increased people's quality of life and their life expectancies.
She said the use of the service reflected changing attitudes to smoking brought about by the bans on tobacco advertising and sponsorship and the restrictions on smoking indoors put in place in recent years.
Graphic health warnings on cigarette packets were also having an impact.
"In January, 10% of Quitline clients said they got the Quitline number from the packets, rising to 30% last month."
The trust last month introduced the Txt2Quit service targeting younger smokers - around 400 people have already used that service.
Ms Glasgow said a combined front across the health sector on tobacco control and stopping smoking was resulting in the national smoking rate falling to its lowest level since monitoring of tobacco use began more than 30 years ago, (19.9% for smokers aged 15 years and over).
