An inquiry into the deaths of 18 people who died in Scotland after using an apparently contaminated batch of heroin - believed to have been responsible for the deaths of at least 16 drug users in Dublin last year - will be held tomorrow.
A Fatal Accident Inquiry (FAI) will open at Glasgow Sheriff Court into the deaths of the men and women.
News of the heroin first came to light just over a year ago after a user was struck down by a mystery illness in England prompting a call for doctors to be on the lookout for similar cases.
More than 30 people across the UK and Ireland are believed to have died after taking the drug, and others had to be treated when they became seriously ill.
A special police unit was established to deal with the spate of deaths and medical experts from the United States were called in to help track down the cause of the mystery deaths.All of the victims developed a serious abscess after they had injected into muscle or accidentally outside a vein. Some of them died within hours of taking the drug.
Greater Glasgow Health Board said post-mortem examinations revealed all of the victims had died as a result of multiple organ failure.
At the time, a spokeswoman for the board said the most likely explanation for the outbreak was an unusual contaminant of a batch of heroin which, when mixed with citric acid, resulted in severe damage of the muscle or tissue where it had been injected into.
