A 'miracle' teenager who battled cancer and needed Britain's fastest ever liver transplant as a child died after taking a lethal cocktail of cocaine and ecstasy.

Sherie-Lea James, 15, from Basildon, suffered a cardiac arrest after taking the Class A drugs in a 29-year-old man's flat - hours after telling her mother she was 'loving life'.

The tragic teenager had been at a party in the one-bed flat in the deprived South Ockendon area of Essex with a friend when she became unwell in the early hours of September 1, 2016.

Paramedics and police rushed to the house after the alarm was raised and took her to hospital.

Doctors at Basildon University Hospital tried to resuscitate her but Sherie-Lea could not be saved and her friend was also hospitalised.

Today Essex Coroner's Court, in Chelmsford, heard that she had taken the drugs voluntary and died of MDMA intoxication together with cocaine.

DCI Stephen Jennings, who led an investigation into her death said two men were arrested, and police are currently considering charges of 'unlawful supply'.

He revealed those charges currently are 'with the CPS'

Her mother Sam says her daughter 'hated drugs' and cannot understand why she died

Speaking about the drugs in her system he said: 'The levels of the MDMA were considerably higher but that with the combination of the cocaine was the cause of death.'

Sherie-Lea battled liver cancer as a baby and is survived by three siblings.

When The Billericay School pupil was just 20 months old doctors discovered that she had a liver tumour that weighed six pounds.

Following a year of chemotherapy she had the country's fastest liver transplant lasting just 45 minutes in July 2002.

At the time of her death devastated mum Sam was planning a dream trip away to America following her GCSEs.

She wept throughout the brief hearing as she sat next to her son.

Eleanor McGann, area coroner, said: 'This is very sad, she was a young girl who thought she was just enjoying herself

'Sadly there are many young people who take these drugs thinking it is just fun and in the end it has absolutely tragic consequences.

'I hope other young people will think about the consequences of taking these illegal drugs

'They are not just fun they are horribly dangerous, if a young person is stopped from taking drugs like this again perhaps Sherie-Lea's death might have had some use.'

Mrs McGann told the devastated family it was clear Sherie-Lea was clearly loved and recorded a conclusion that her death was drug related.
