Nearly one in four of us is still a smoker.
Most smokers light up daily and around 4pc occasionally.
The high rates of smoking have emerged in the 2015 annual report on the Tobacco Free Ireland Action Plan.
"Smoking is the greatest single cause of preventable illness and premature death in Ireland, killing over 5,600 people a year,” said Health Promotion Minister, Marcella Corcoran Kennedy.
“Smoking prevalence in Ireland remains unacceptably high.”
The action plan was launched in 2013 and aims to have no more than 5pc smoking by 2025.
The report pointed to moves to reduce smoking including outlawing smoking in cars if there is a child on board.
It also includes the development of legislation to provide for standardised packaging of tobacco products and the further development of support available by the HSE to help smokers quit.
