Gwynedd and Powys saw an increase in the rate of adult smokers last year, new figures show, but the rate fell in Ceredigion.

Office for National Statistics figures recorded the lowest proportion of smokers in the UK to date, with e-cigarettes playing a "major role" in the decline.

The ONS data shows 15 per cent of people aged over 18 in Gwynedd were smokers in 2021, up slightly from 14.5 per cent the year before. However, it was a fall from 18.7 per cent five years ago.

Last year, a further 26 per cent of adults in the area were ex-smokers while 59 per cent had never smoked.

Men in Gwynedd smoked more than women with 17.2 per cent taking up cigarettes, while 12.9 per cent of women smoked.

In Powys, 15.5 per cent of adults were smokers in 2021, up from 14.2 per cent the year before. It was also an increase from 15.4 per cent five years ago.

Last year, a further 26 per cent of adults in the area were ex-smokers while 58.6 per cent had never smoked.

Men in Powys smoked more than women with 16.6 per cent taking up cigarettes, while 14.3 per cent of women smoked.

In Ceredigion, however, the ONS data shows 16.6 per cent of people were smokers in 2021, down slightly from 16.9 per cent. However, it was a marginal increase from 16.5 per cent five years ago.

Last year, a further 26.2 per cent of adults in the area were ex-smokers while 57.2 per cent had never smoked.

Men in Ceredigion smoked more than women with 20.5 per cent taking up cigarettes, while 12.8 per cent of women smoked.

Hazel Cheeseman, deputy chief executive of Action on Smoking and Health, welcomed the overall fall in smoking levels, but said the government must not become "complacent".

Ms Cheeseman added that without a new tobacco plan from the government, "the vision of being smoke free by 2030" will not be met.

Nationally, 14.1 per cent of adults in Wales were smokers with those aged from 45 to 54 (18.3 per cent) making up the highest proportion of smokers.

Across the UK, 13.3 per cent of adults smoked cigarettes in 2021, down from 14.0 per cent last year and a significant fall from 20.2 per cent a decade ago.

The ONS said the increase in people taking up e-cigarettes has played a "major role" in the fall with a separate survey finding 7.7 per cent of those aged 16 and over in Great Britain last year used an e-cigarette daily or occasionally.

It was an increase from 2020, when 6.2 per cent of people reported daily or occasional e-cigarette use.

The survey found that the proportion of vapers was highest among current cigarette smokers (24.6 per cent) and ex-cigarette smokers (14.8 per cent), with only 1.7 per cent of people who have never smoked reporting that they vaped.
