In this report, the Health Research Board presents the results of a study that aimed to estimate the prevalence of problematic opioid use in Ireland from 2015 to 2019 using a four-source capture-recapture method.
In total, there were an estimated 19,875 problematic opioid users in Ireland in 2019
The majority of problematic opioid users were male (72.3%)
There were 11,729 problematic opioid users in Co Dublin in 2019
More than two-thirds (72.93) of problematic opioid users were in the older 35–64-year-old age group.
The prevalence of problematic opioid use among younger age groups (15–24-year-olds
and 25–34-year-olds) appears to be in decline
