The survey also found that three-?quarters of 18 to 24 year olds regret their drunken behaviour, including not knowing how they got home, having a one-night stand or ending up in hospital.
The survey was conducted to launch Drinkaware’s latest Why Let Good Times Go Bad? campaign, being run with the backing of 40 drinks companies.
More than 7,000 supermarkets and off-licences will use in-store signs to provide “tips for smarter drinking”.
The campaign will also be branded on 13 million drinks packs, and posters will appear in phone boxes and train stations.
Drinkaware chief executive Chris Sorek said: “We know most young adults drink, but the fact that so many get into situations they regret means we should nudge them to change their behaviour.”
