Alcohol-free and low-alcohol drinks are more likely to be bought by heavy drinkers than lighter ones, a study suggests.

Research from the University of Sheffield found one third of adults have had an alcohol-free or low volume drink in the last year.

But the report found those who drank alcohol at "risky" levels were more likely to consume them regularly.

The study, by the university's addictions research group (SARG), analysed household purchasing data and found that 96% of households which bought the so-called "no/lo" drinks also bought alcoholic ones.

It also suggested the availability of no/lo beers in pubs, bars and restaurants had increased, with 74% of outlets selling them in 2023.
