A new study among Ireland's top GAA players has found high rates of binge drinking.
The survey of over 700 active inter-county camogie, football and hurling players found two-thirds had experienced alcohol-related harm within the last 12 months.
It found more players consume alcohol than the general public.
It also pointed to a a seasonal drinking pattern, with more being consumed in the off-season.
90% percent of players drink 6 or more drinks in a single session, compared with 55% of 24 to 35 year old's in general.
Dr Kieran Murray, the lead author of the study, says a quarter of respondents missed college while 1 in 10 described harm to home life.
One in every 50 had to visit the emergency department with an alcohol related issue.
