HHC now classified as Illegal Drug

New classification strengthens enforcement powers

Hexahydrocannabinol (HHC) are now classified as a Schedule controlled drug in a deicison that makes it illegal to import, export, produce, possess, sell, or supply products containing the chemical in Ireland.

The Minister for Health, Jennifer Carroll MacNeill TD, alongside Ministers Jennifer Murnane O’Connor TD and Mary Butler TD, made the announcement today regarding the a semi-synthetic cannabinoid with effects similar to cannabis.

It has been available in various forms such as vape pens, oils, edibles, and tinctures, often marketed to young people in appealing packaging.

Since its first detection in Ireland in 2022, HHC has been linked to hospitalisations and psychosis. A recent study at University Hospital Galway found it was the second most common drug among patients presenting with psychosis over a 21-month period.

The latest move is part of a broader classification of 14 new substances, including synthetic opioids and cannabinoids, identified by both the EU and UN as significant threats to public health.

The new classification strengthens enforcement powers for An Garda Síochána to tackle illicit drug trade.

Minister Carroll MacNeill criticised the marketing of HHC to young people and emphasised the need for legal tools to address emerging drug threats quickly.

Minister Murnane O’Connor meanwhile highlighted the drug's impact on public health and called for stronger education and prevention initiatives.

Minister Butler lastly noted that HHC was implicated in one-third of first-time psychosis cases in Galway, underlining its severe mental health risks.

The Department of Health is also expanding treatment services and public awareness efforts, reinforcing a health-led approach to drug use and prioritising protection, prevention, and recovery support for those affected.
