GLASGOW has suffered an "unpredecented" wave of drugs deaths thanks to Street Valium, experts said today.

NHS, police and council figures joined forces to make a rare warning over the pills, which are sometimes called Street Blues.

It is believed that almost 20 people in council-supported homeless accommodation have died after taking the drugs since early December alone.

Officials said the drug - often when mixed with other substances - may be behind a dramatic rise in fatal and non-fatal overdoses in the city.

Early data, they said, showed an overall 43 per cent rise in the number of people who died of drugs overdoses in Glasgow from January to October last year compared with the same period in 2017.

That comes on top of early informal projections that Scotland's annual toll of drugs deaths for 2018 will easily top 1000, perhaps 1100, yet another record high. Experts already believe this is a public health emergency.

There has also been an increase in the number of people being treated for non-fatal overdoses at hospitals and by crisis services across the city.

Reported use of Naloxone, a drug that can reverse the effects of an opiate overdose which is supplied to drug users and trained relatives and friends – have also increased.

Experts and service providers also fear that a recent spate of deaths among people in settled homelessness accommodation are also linked to Blues – however, full toxicology results are not yet available.

These people were also known to have complex health and social problems.

Frontline services continue to warn known drug users about the risk posed by the pills – especially if taken with other illegal substances like heroin and prescribed opiates, such as Methadone.

But dealers are flooding Scotland with it, producing it quickly and in vast quantities and selling it for pennies to vulnerable people.

Saket Priyadarshi, Associate Medical Director, NHS Greater Glasgow & Clyde Addiction Services, said he feared street blues were currently a factor in the vast majority of fatal drug overdoses in the city.

He added: “I have been very concerned about the use of street blues for some time now.

"When people buy street blues, they do not know what is in the pills. The quality and dosage can be very variable.

"People might think they are taking diazepam but it may be other much more potent benzodiazepines such as Etizolam.

"The use of this drug in particular is associated with severe harm - from non-fatal overdoses and presentations to emergency departments to fatalities. It is particularly dangerous when used in combination with other drugs like heroin and even prescribed methadone.

“Although final toxicology is not yet available on the recent deaths in Glasgow, all the evidence suggests that the use of street blues is associated with the worrying trend of increasing drug related deaths.”

Susanne Millar, Chair of Glasgow’s Alcohol & Drug Partnership, described a number of drug deaths among people in settled homeless accommodation as “unprecedented”.

She said: “Glasgow is currently experiencing a an unprecedented number of fatal and non-fatal overdoses believed to be linked to the use of street Valium, although we won’t know conclusively until we have all the toxicology.

“People are dicing with death by taking this drug, particularly if it is mixed with alcohol and other drugs. Warnings have been issued to people by homelessness and addictions services but sadly dealers are targeting the most vulnerable.

“A number of deaths have taken place among residents of settled homeless accommodation which is tragic and very unusual. Support is being offered to frontline staff who are being confronted by human tragedies when going to check on service users.”

Ms Millar confirmed this issue will be discussed at the City’s Alcohol and Drug Partnership meeting this week.

Last month, a drugs gang was jailed for producing at least £1.6million worth of street valium on an industrial scale in a garage in Paisley. The court heard that Police Scotland raided the garage and seized a pill press capable of producing 250,000 tablets an hour.

Chief Inspector Michael Duddy, Police Scotland Greater Glasgow Division, Partnerships & Resourcing said: "Police Scotland in Glasgow continues to work with health and social care partners as part of the Glasgow City Alcohol and Drug Partnership to monitor and respond to drug trends including incidences of suspected drug related deaths in order to inform care, treatment and police activity."

Drug users are being urged to beware of street Valium and to seek advice on overdose prevention from addictions services. Their families and friends are encouraged to obtain training on the use of, and supplies of, naloxone.
