The first of the plain cigarette packets have hit shelves around the country.
Tobacco products bearing the new standardised packaging are now available in some Irish retail outlets.
From September, all cigarettes and all other tobacco products will have to be sold in plain or standardised packaging by law.
This comes following the Public Health (Standardised Packaging of Tobacco) Act 2015.
All cigarette boxes will be in the same plain neutral colour, with health warnings printed on the package.
Minister Catherine Byrne has welcomed the news that the boxes are now available in some stores.
"Our aim is to decrease the appeal of tobacco products, to increase the effectiveness of health warnings and to reduce the chances of consumers being misled about the harmful effects of smoking," she said.
"This packaging makes it plain that cigarettes are bad for your health."
The standardised packaging is just one of a number of measures outlined in the 'Tobacco Free Ireland' programme.
