Just 79 individuals have been issued with fines for smoking in restricted areas after one year of the smoking ban in enclosed public places in Wales.
On the anniversary of the ban the Welsh Assembly released figures that showed 84% of the Welsh population were in support of the ban, compared to 71% before the legalisation was introduced.
Dr Tony Jewell, chief medical officer for Wales, said: "The widespread public acceptance of and support for the legislation reflects the impact of the Assembly Government's campaign to raise public awareness of the health risks of exposure to second-hand tobacco smoke."
"The high rates of compliance are also due to the extensive work done by local authorities to inform and support businesses," he added.
Any premises failing to stop smoking taking place can be fined up to £2,500, while individuals face a spot-fine of £50 for smoking, which will rise to £200 if it goes to court.
