Children preparing for their confirmation will be asked to make a commitment not to vape before they're 18.
The Confirmation Pledge has been updated to include vapes and cigarettes.
The promise not to use e-cigarettes will be added to abstaining from drinking alcohol or doing drugs.
Bishop Michael Router, of the Irish Bishops' Drugs Initiative is a native of Virginia in Co Cavan.
Speaking on this morning's Joe Finnegan Show, The Bishop of Armagh said protecting children's health is the core aim of 'The Pledge'.
Bishop Router explained: "Central to the mission of the Irish Bishop’s Drugs Initiative is the conviction that prevention and early intervention are as vital as treatment and recovery. Education and formation, especially of young people, are essential if we are to respond meaningfully to substance misuse.
"In this context, I warmly welcome the rewording of the Confirmation Pledge to explicitly include vaping and cigarette smoking, alongside alcohol and illicit drugs. This development reflects a thoughtful and prayerful response to the lived realities of young people today.
"Vaping has become widespread and is often presented in ways that obscure its risks and normalise dependency. By naming these realities clearly, the Church affirms her commitment to truth and to the wellbeing of young people."
