There's been a 171% increase in the number of young people being treated for cocaine use in Ireland.
The latest HRB report also found substance related hospitalisations are on the rise among 15-24 year olds.
The data collected from the Health Research Board between 2011 and 2019, looked at alcohol and drug use among adolescents.
Cannabis remains the most common drug, but ecstasy and cocaine use among young people in Ireland was the second highest in Europe.
Although drug-related problems are on the rise, it seems people are starting to drink alcohol at an older age.
In 2002 the average age people had their first drink was 15.6 years.
That has increased to 16.6 years in 2019.
However one-in-three people aged between 15 and 24 have an alcohol use disorder, with Ireland ranking 7th in Europe for reports of being drunk.
