1 in 5 of Irish adults is classified as a hazardous drinker, according to the 2019 Drinkaware Index report, which is published today.
The report reveals that 19% of people exceed binge-drinking levels on a typical drinking occasion and that 74% believe drinking to excess is just 'part of Irish culture'.
The study also shows worrying drinking trends among the under 25s.
On average, the current generation of under-25s had their first alcoholic drink at 14.3 years, compared to the national average of 15.5 years.
A third of under 25s admit to binge drinking on a weekly basis, while more than a quarter acknowledge that their drinking habits could cause future health problems.
Commenting, Sheena Horgan, CEO of Drinkaware, said: 'The Drinkaware Index research highlights that a significant number of Irish adults are drinking at a level that may be putting their health at risk. Of particular concern is that these drinking habits appear even more embedded among younger people, with 64% of under-25s stating that they often drink as a coping mechanism.'
