The HSE Emerging Drug Trends lab has identified meclonazepam in two separate products being sold as counterfeit benzodiazepines (alprazolam) in the Dublin region.
Meclonazepam is a potent new psychoactive substance ‘NPS’ or ‘designer’ benzodiazepine.
It has been associated with adverse health effects including severe sedation or fatality.
It’s safer not use to use, but if you choose to use create a rescue plan, avoid using alone and get medical help immediately.
