The research was conducted by the Tobacco-Free Research Institute Ireland.
Smoking rates among teenagers in Ireland have begun to rise, following almost 20 years of decline
The figures are based on a survey of smoking consumption rates among around 3,500 pupils aged 15-16 years old.
Research by TFRI shows teenage smoking levels had decreased from 41% in 1995 to 13.1% by 2015.
That increased, however, to14.% in 2019.
The data also showed those who used an e-cigarette were 50 percent more likely to smoke.
Prof. Luke Clancy is Director General of the Tobacco-Free Research Institute Ireland and Adjunct Professor at the Technological University of Dublin.
He joined Eoin Beatty on Tuesday's edition of Kildare Today:
