A HEARTBROKEN mum of a student killed by laughing gas has called on ministers to make it a class A drug.
Sharon Cook, 54, lost 24-year-old daughter Ellen after she became hooked on the party drug.
Ellen, a business student from Gerrards Cross, Bucks, became gravely ill in February last year and died in hospital the following dayUnknown
Her devastated mum spoke of the moment she was called by medics.
Sharon told The Sun: “I got a phone call saying that she died of a heart attack and a stroke.
“They told me it was because of nitrous oxide.
“I had no idea she was addicted.”
Ellen, a business student from Gerrards Cross, Bucks, became gravely ill in February last year and died in hospital the following day.
Mum-of-two Sharon, who works as a delivery driver, called on the Government to tighten sentences.
She said: “It is illegal now, but it’s too late for Ellen. More needs to be done.
“Nitrous oxide can kill you. It should be a class A drug.
“If you are caught selling it you should be locked up. Don’t mess with it. It’s not worth your life.”
A full inquest into Ellen’s death will be held this month.
