HHC Drug Linked to Severe Psychosis Being Sold Openly in Irish Vape Shops Despite Ban – €2 Million Garda Raid Across Four Counties

Major Garda Operation Targets Illegal HHC Sales in Castlebar, Longford, Drogheda and Carlow

A high-ranking Garda has warned that a dangerous drug known to cause severe psychosis and other mental health issues is still being sold openly in some Irish shops, even though it is illegal.

This comes after the Garda National Drugs & Organised Crime Bureau (GNDOCB) carried out coordinated raids on vape shops and related premises, seizing illicit substances worth over €2 million. Searches targeted locations in Castlebar (Co Mayo), Longford, Drogheda (Co Louth), and Carlow on July 2 and July 8, 2026. Two men in their 30s were arrested.

Detective Superintendent Issues Strong Warning on Open Sales

Detective Superintendent Shane McCormack from the National Drugs Strategy Office described the situation as a serious concern. He confirmed that HHC products continue to be sold openly in certain shops despite being banned since July 2025 under the Misuse of Drugs Act.

“They’re illegal and they are sold openly in some shops and hence as we become aware of this, An Garda Síochána develops operations to engage with that problem,” McCormack told RTÉ Radio 1. Products are often labelled with descriptions suggesting a cannabis-like effect, such as “smooth buzz” or “light buzz,” making their illegal status clear to many buyers.

While some HHC is produced within Ireland, the majority is smuggled in from abroad. The recent raids recovered large quantities of cannabis-infused jellies, cannabis oil-infused vapes, and “reefer” cigarettes containing HHC and THC.

HHC Risks: Why This Semi-Synthetic Cannabinoid Is So Dangerous

Hexahydrocannabinol (HHC) is a semi-synthetic cannabinoid that was previously marketed as a legal alternative to cannabis. It was added to Schedule 1 of the Misuse of Drugs Act in July 2025 due to growing public health fears.

Key concerns include:

• Psychosis and Mental Health Crises: Multiple Irish case studies link HHC to psychotic episodes, including delusions, auditory hallucinations, paranoia, and detachment from reality. In some hospital data, HHC has ranked as the second most common substance associated with psychosis presentations.
• High Usage Rates: Surveys show significant lifetime use, with many people obtaining products easily from high street vape shops.
• Other Side Effects: Users have reported anxiety, panic attacks, dizziness, dissociation, depression, and withdrawal symptoms. Young people are particularly vulnerable.

Health authorities, including the College of Psychiatrists of Ireland, have highlighted cases where users required extended inpatient treatment. The unpredictability of unregulated products increases the risks.

Ongoing Enforcement and Public Health Response

Garda operations continue nationwide to tackle the illegal sale of HHC and similar substances. The €2 million seizure demonstrates the scale of the problem and the commitment to disrupting supply chains involving both domestic distribution and international smuggling.

Despite the ban, some retailers appear to be continuing sales, prompting further targeted raids. Authorities urge the public to report suspected illegal activity.

What to Do If You Have Used HHC or Need Help

If you or a loved one are experiencing mental health issues after using HHC or similar products, seek medical help immediately. Contact your GP, local mental health services, or the HSE Drugs and Alcohol Helpline on 1800 459 459.

To report illegal sales or suspicious activity, call Gardaí on 1800 666 111 or use Crimestoppers anonymously.

Parents, educators, and retailers all have a role to play in protecting young people from these harmful products.
