Seán Canney TD, Minister of State for International and Road Transport, Logistics, Rail and Ports, has welcomed the Government’s decision to classify Hexahydrocannabinol (HHC) as a Schedule 1 controlled drug under the Misuse of Drugs Act 1977.

The move means that the import, export, production, possession, sale, and supply of HHC is now illegal in Ireland.

Minister Canney said: “The decision to ban HHC is a vital and timely measure to protect public health—particularly the mental health of our young people. The evidence from University Hospital Galway and elsewhere is deeply concerning, and it’s clear that swift action was needed.”

“I commend my Government colleagues for responding decisively to the threat posed by synthetic cannabinoids like HHC, and I fully support the additional enforcement powers now given to An Garda Síochána in tackling the supply of these dangerous substances.”

HHC, a semi-synthetic cannabinoid with similar effects to cannabis, has been linked to psychotic episodes and hospitalisations since it was first detected in Ireland in 2022.

A notable study conducted by clinicians at University Hospital Galway found that HHC was the second most commonly detected drug among patients presenting with psychosis, accounting for nearly a third of first-time psychotic episodes over a 21-month period.

The classification of HHC comes as part of a wider response to synthetic drugs. It is one of 14 substances, including synthetic opioids and cannabinoids, now newly controlled following alerts by both the European Union and United Nations on their serious risk to public health.

Minister Canney added: “We must take a comprehensive, health-led approach to drug misuse—one that includes strong enforcement, effective treatment services, and practical supports for families and communities.”

“I urge anyone concerned about drug use to visit www.drugs.ie or contact the HSE Drugs and Alcohol Helpline for confidential, expert advice.”
