A total of 50,304 cases were treated for problem alcohol use in Ireland between 2015 and 2021, according to the latest figures published by the Health Research Board (HRB).

The 2021 report on data from the National Drug Treatment Reporting System (NDTRS) shows a decrease in treated cases from 7,618 in 2015 to 6,859 in 2021, together with a slight drop in the proportion of new cases reported.

  • Almost two in every three cases reported in 2021 were classified as alcohol dependent.
  • Where alcohol treatment cases were using additional drugs, cannabis was the most common and cocaine the second most common additional drug recorded. 
  • In 2021, over one in five cases treated for alcohol were currently living with children aged 17 years or younger.

Dr Mairéad O’Driscoll, HRB Chief Executive, said, “Alcohol remains the main problem drug that people seek treatment for in Ireland. As the timeframe covered by the latest data spans the emergence of the COVID-19 pandemic and related restrictions, the HRB figures are all the more important to monitor the impact that lockdown may have had on problem alcohol use and treatment trends.”

Dr Suzi Lyons, Senior Researcher at the HRB, said, “While we have seen a decline in the number cases reported over the seven-year period, this must be viewed in the context of limited access to services due to COVID-19 restrictions. Even though the numbers have decreased, we are seeing that the trends remain consistent. For example, half of all cases treated started to drink alcohol by the age of 16 and two out of three cases who are new to treatment are already classified as alcohol dependent when they enter treatment. We are also continuing to see cases mixing alcohol with other drugs with almost one in four reporting problem use of other drugs. This is a concern as mixing drugs can impact recovery and increase risk of overdose.” 

Key findings 2021

Level of problem alcohol use

  • In 2021, the median age at which cases first started drinking alcohol was 16 years, unchanged from previous years. 
  • Almost two in every three cases were classified as alcohol dependent.  
  • In 2021, 62% of new cases were classified as alcohol dependent, compared to 57% in 2015.  
  • The proportion of previously treated cases classified as alcohol dependent increased from 67% in 2015 to 70% in 2021.

Commenting on the trends across male and female cases, Dr Suzi Lyons says: “Women seeking treatment for problem alcohol use are consuming a median number of 15 standard drinks on a typical drinking day, with spirits and wine being the preferred alcohol. For men, that figure is 20 standard drinks, with beer followed closely by spirits as the alcohol of choice. When we consider that HSE low-risk guidelines5 suggest a weekly limit for alcohol of 11 standard drinks over a week for women and 17 for men, these patterns will clearly have a significant impact on health and well-being.” 

Socio-demographics

  • In 2021, the median age of treated cases was 42 years, a small increase from 41 in previous years
  • The majority of cases in 2021 were male (63%). 
  • The proportion of cases aged 17 years or younger increased slightly from 1.4% in 2015 to 1.6% in 2021.
  • The proportion of cases who identified as Irish Traveller ethnicity was 1.9% in 2015 and 2.4% in 2021.
  • Almost half of cases in 2021 were unemployed. 
  • In 2021, 8% of cases were homeless – a slight increase from 7.5% in 2015. 
  • In 2021, one in five of cases treated for alcohol were currently living with children aged 17 years or younger. A further fifth of all cases had children aged 17 years or younger who were not currently living with them.

Polydrug use 

  • Polydrug use was reported by almost one-quarter of those treated for problem alcohol use in 2021. This was an increase from under one-fifth in 2015.
  • Cannabis was the most common additional drug used. The proportion of cases reporting cannabis use declined from 60% in 2015 to 55% in 2021. 
  • Cocaine was the second most common additional drug recorded. This increased from 33% in 2015 to 54% in 2021. 
  • 47% of female cases and 57% of male cases reported with cocaine as an additional problem in 2021.
