The Health Minister is welcoming new minimum pricing laws for alcohol which take effect today.
Stephen Donnelly says the minimum price is directly proportionate to the amount of pure alcohol in the drink.
There will be a minimum cost based on grams of alcohol, with one gram costing at least 10 cent.
Alcohol Action Ireland CEO, Sheila Gilheaney says it's a positive move that tackles problem and under-age boozing.
"We know that it is a target measure which targets those of us who are drinking at very high levels, in particular young people who have had access to very cheap and very strong alcohol.
"This is something that has been fuelling a large amount of alcohol harm in Ireland."
