Almost half of Irish smokers have tried to quit in the past year, with just 10% doing so successfully.
According to the latest Healthy Ireland Survey, almost half of those who were successful in quitting did so through willpower alone, with around a third using e-cigarettes as an aid.
The study also found that the recruitment of new smokers remains high with 20% of under-25s currently smoking, with women more likely than men to take up the habit.
Drinkers living in more affluent areas are more likely than those living in more deprived areas to consume alcohol at least once a week.
However the research also found that the extent of binge drinking among those in more deprived areas was higher.
Binge drinking rates were also higher among men and under-25s.
The Healthy Ireland Survey is the second of its kind and was launched this morning by Minister of State for Health Promotion, Marcella Corcoran Kennedy.
