Class C drug Benzodiazepine — known on the street as ‘blues’ — caused a total of 10 deaths in 2013, compared to three people who died of deadly substance heroin.

The statistics were revealed by the General Register Office for Scotland and showed that Renfrewshire has one of the highest numbers of deaths per 1,000 of population, coming in fourth place below the likes of Glasgow and West Dumbartonshire.

Valium is used by 1.5 million people in the whole of Britain to treat wide-ranging problems including anxiety, panic attacks, insomnia, muscle spasms, restless legs syndrome and alcohol withdrawal.

And it was the drug responsible for the most deaths in Renfrewshire, followed by methadone, which caused seven deaths, and alcohol, which caused five.

However the stats said that more than one drug could be counted for each death — such as mixing the drug with alcohol or other substances.

The survey did not include deaths in Renfrewshire caused by popularly used legal highs, such as ‘Meow Meow’ and ‘Mary Jane.’ In April this year, The Gazette reported how a pretty bride-to-be was robbed of the chance to marry the love of her life after downing a suspected lethal drug cocktail at a Renfrew house party.

The lifeless body of tragic Helen Henderson was found on Sunday, April 13, after the party. It’s thought Helen took Meow Meow and Ketamine which also resulted in four other revellers being hospitalised.

Rangers-daft Helen, 19, fiancé Calum Smith, 23, and other pals had been partying at their flat in the burgh town’s Paisley Road over the course of the weekend.

It’s understood the group were drowning their sorrows after their beloved Ibrox side were sent crashing out of the Scottish Cup by Dundee United.

This week police chiefs issued a drugs warning after another teenager from Glasgow fell ill and died following a house party.

Although it is still unclear at this time what the cause of death was, it has been suggested that she may have taken some form of ecstasy-type drug.

Chief Superindendent Ciorstan Shearer of Police Scotland said: “My sympathies are with the girl’s family and we have specially trained officers providing assistance and support to them at this sad time.

“The 16-year-old girl returned home feeling unwell at around 5am and she died within her home several hours later.

“As it has been suggested that she may have taken some form of ecstasy-type drug, it is vital that we trace the other people who were also at the party to ensure that they are safe and well.

“Police Scotland is working with its partner agencies, including health officials, in connection with this risk.”
