HHC Vapes: Addiction Crisis Prompts Urgent Ban
A synthetic drug found in some vapes and edibles is causing serious mental health problems in young people. Authorities are moving to ban Hexahydrocannabinol (HHC), following a surge in addiction cases and psychosis-like symptoms.
Growing Concerns Over HHC Use
Figures reveal that 169 young individuals sought treatment for HHC-related issues within the last year and a half. The substance, sold in vape shops, mimics the effects of THC, the active compound in cannabis, and is readily available across the country.
John, an 18-year-old, shared his harrowing experience with HHC, describing the terrifying voices and psychotic episodes he endured. The easy accessibility of the vapes exacerbated his addiction and mental health struggles.
Joe, another user, reflected on how HHC usage turned his world upside down, leading to psychosis and profound changes in his personality. He now suffers daily effects, but feels fortunate to have sought treatment before his condition worsened.
“I heard voices screaming in my head, it was absolutely terrifying. I thought it would never go away.”
—John, Former HHC User
The College of Psychiatrists of Ireland is strongly advocating for a ban on HHC. A recent study indicated a 40% increase in adolescent substance abuse cases since 2020 (Research Report).
Mental Health Impacts and Expert Warnings
Sara Cassidy, Head of Clinical Services at Aiséirí Addiction Treatment Centre, noted a sharp increase in HHC addiction cases. She highlighted the potential for enduring symptoms, especially in young people with developing brains, even after ceasing use.
Professor Bobby Smyth, a Consultant Child and Adolescent Psychiatrist, has been urging the government to ban HHC for a year. He questions how this drug, which barely existed three years ago, gained such widespread availability.
Government Response and Future Outlook
The Department of Health is preparing to add HHC to the list of prohibited substances, making its sale or supply illegal. This move comes in response to growing concerns over the drug’s harmful effects on young people.
Joe hopes the ban will prevent others from suffering the same fate. John expressed his desire for the products to be removed from shops to spare others the ordeal he endured.

The imminent ban on HHC represents a crucial step in protecting young people. However, experts like Professor Smyth stress the importance of learning from this situation to prevent similar issues in the future.
