The heartbroken mum of a 15-year-old girl who died after taking ecstasy has urged young people to think about the deadly consequences of drugs.
Leah Heyes collapsed in a car park after swallowing two grape-sized MDMA "bombs" in Northallerton, North Yorkshire, in May last year.
She was taken to hospital but later died.
Two teenagers were jailed at Teesside Crown Court on Monday for supplying class A drugs.
Mitchell Southern, 19, bought the MDMA crystals from dealer Connor Kirkwood, 18, before he prepared "bombs" of the drugs for Leah and a friend of hers.
Southern was sentenced to 12 months in a young offender institution (YOI), while Kirkwood was locked up for 21 months in a YOI.
Leah’s mum Kerry Roberts paid tribute to her daughter from Northallerton, North Yorkshire.
She said: "We miss Leah every day, her death left a huge hole in our lives that can never be filled.
"No sentence can ever change that, but what we do wish for is for young people to realise the deadly consequences of taking drugs.
"That adults are not just saying they are dangerous to spoil your fun, but that you truly understand how dangerous they are.
"You have your whole life ahead of you, please don't risk losing it.
"If Leah's death has not made you think twice, what will?"
Police investigating her death tried to question the large group of teenagers seen with her on the night she died, but only two provided statements, the court heard.
One of them, who took MDMA with Leah, said Southern made "bombs" from the ecstasy crystals he had bought with their £20 and handed them over, it was said.
The girl said Southern told them: "Yous are going to end up f***** up on this."
Victoria Lamballe, prosecuting, said Leah aspired to a career in health and beauty.
She added: "She was very much looking forward to becoming a big sister - her mother was three months' pregnant at the time Leah passed away."
Judge Jonathan Carroll said the case was "truly tragic" and Leah had "everything to live for".
He added: "This case is here for anybody and everybody who might think that - drugs destroy lives."
Southern, of Thirsk, North Yorkshire, admitted a single count of supplying class A drugs.
He pleaded guilty on the basis he was friends with Leah and he approached Kirkwood on her behalf, passing on her money to buy MDMA from him.
Kirkwood, of Dishforth, admitted supplying the MDMA and a separate charge relating to a £30 cocaine deal on the basis he was not there when Leah took the fatal dose.
Helen Chapman, defending Kirkwood, said: "He is sorry that he dealt drugs to that group of young people that night and that his actions led to the death of Leah."
Robert Mochrie, defending Southern, said: "Hopefully if there is any good to come from this, it is that those in the local community will be acutely aware of what happened and will chose to lead their lives without the use of recreational drugs."
