LIMERICK was among the counties with the lowest number of people being treated for alcohol abuse between 2009 and 2013, according to a new report from the Health Research Board. Waterford, Donegal, Sligo, Leitrim and Carlow had the highest numbers of people presenting for treatment. These counties reported more than 240 cases per 100,000 of the population aged 15 to 64 between 2009 and 2013. Numbers for the same period were lowest in Limerick, Roscommon, Clare, Mayo and Meath, with less than 75 cases per 100,000 of the population. The research found that half of the people who presented for treatment started drinking aged 15 or younger. The figures also showed that almost one in five people treated for alcohol abuse in 2013 used at least one other drug.
