A newly popular form of ecstasy is being blamed for the death of an Irishman in Spain this week.
Gamma hydroxybutyrate, also called GBH or liquid ecstasy has been the subject of serious health warnings after it became popular among those on the Europe's club circuit.
A 27-year-old Sligo man holidaying in the world's club capital, Ibiza, died after apparently taking the drug on Sunday night.
A post mortem was carried out on the man yesterday and Spanish authorities today said he died from kidney failure. Sources locally say the cause of death was "poisoning due to amphetamines and derivatives".
A toxicology report to establish whether the drugs found in the man's system were adulterated has yet to be completed.
He was admitted to hospital at around 4.15am on Monday morning and died 12.40pm that afternoon.
The Department of Foreign Affairs is keeping the man's family informed and is assisting in efforts to repatriate the his remains today.
He was one of 25 people treated at the Playa d'en Bossa resort after a batch of what is thought to have been a "contaminated" batch of GBH was circulated.
Eleven people are still being treated in hospital. The Spanish Ministry of the Interior has described the mount of admissions to hospital connected to the taking of GBH as "worrisome".
Scientists have warned, that the difference between a relatively safe dose and a potentially dangerous, even lethal dose, is quite small and therefore the risk involved is increased.
It is generally mixed in a drink and in small quantities can have a sedative effect - police in Britain believe it to have been used in date rapes. It is a depressant that acts on the central nervous system but is also variously described by medical experts as euphoriant and aphrodisiac
It can be particularly dangerous when mixed with alcohol and can lead to hallucinations, convulsions and coma.
