Louella Fletcher-Michie died at Bestival in 2017

As reported in the Daily Echo, Louella Fletcher-Michie, 24, took class A substance 2-CP at the Dorset festival on September 10 2017. She died in woodland an hour before her 25th birthday.

It is alleged she was given drugs by her boyfriend Ceon Broughton, 29.

Broughton, of Enfield, north London, denies manslaughter by gross negligence and supplying the drug.

During evidence given by Professor Charles Deakin, a consultant in cardiac anaesthesia and intensive care, jurors at Winchester Crown Court were told of the experiences of others who had taken the drug.

Stephen Kamlish QC, defending, said a report described it as "long-lasting and like LSD".

He added: "Some people have found it to be intense and challenging, particularly when taken in high doses."

One user in the report stated: "The experience was not fun.

"Around the ninth hour I began to feel bummed out by the duration of it. I just wanted to sleep."

Another stated: "Trees around me were frightening, took on the characteristics of demons and giant dinosaur creatures" while a third said: "This drug is physically and psychologically draining, I realised how intense and unforgiving 2-CP is."

Mr Kamlish has previously told the trial "no-one has ever been known to die from taking this drug (2-CP) or taking an overdose".

The court previously heard Miss Fletcher-Michie, the daughter of Holby City star John Michie, was found dead by a security steward in the woodland, 400 metres from the festival's hospital tent, at about 1am.

Prof Deakin told the court he believed Miss Fletcher-Michie had a "very good chance of survival" had she received medical help at an early enough stage.

Detective Sergeant David Wise, of Dorset Police, said during his evidence that sniffer dogs alerted officers to 225 people entering the festival site. Of those, 36 per cent gave positive results for drugs. No 2-CP was recovered.

The trial continues.
