A teenage girl died after taking double the amount of MDMA as her friends because she was “determined to have a good night” at The O2, an inquest has heard.
Emily Lyon, 17, took 0.5 grams of MDMA before she fell ill at the Red Bull Culture Clash event in North Greenwich on June 17 last year.
Emily, who lived in Broom Road, Teddington, and her group of friends arranged to buy two grams of the drug from another pupil at Esher College.
Giving evidence at the inquest today at Inner South London Coroners Court, Detective Constable Scott Albert said: “She wanted to have a good night that night, exams had come to an end, they [her friends] made it clear that she was determined to have a good night that night.”
The friends split the Class A drugs on the way to the event, and Emily then took a further 0.25 grams of powdered MDMA before entering the area.
The inquest heard she was worried the first dose would not give her a ‘buzz’ and it would get confiscated by security guards, who had drug dogs.
Shortly after taking the second, fatal dose, she complained she was feeling ill, and was struggling to stand and speak.
Paramedics were called to the venue after friends raised the alarm, but she died at 12.50am the next morning at Queen Elizabeth Hospital in Woolwich.
Det Con Albert said: “She was finding it difficult to stand and communicate, [she was] extremely hot.
“Emily had told him [a friend] she felt very ill because of the second dose and he suggested to her that she just has some water.
“He looks back on that and thinks that if he had got medical attention earlier would that have had a different outcome.”
The court was told that Emily had experimented with the drug once before.
Assistant Coroner Philip Barlow recorded a conclusion of a drug-related death, specifically MDMA or ecstasy.
Friends had paid tribute to the A-level student, who was studying at Esher College when she died, saying she was a "great friend" and a "loving daughter".
Her father, Steve Lyon, warned others of the "tragic consequences" of taking "recreational substances" after her death.
Five other people, including a 16-year-old boy, were taken to hospital after reportedly taking illegal drugs the same night.
Mr Lyon said: "We are absolutely devastated at what has happened and we're struggling to come to terms with it.
"Emily was a wonderful, vibrant young lady. She was a loving daughter and a caring sister, who was much adored by her vast circle of friends.
"It can be seen how these so called 'recreational substances' can result in such tragic consequences for so many people. Those who take them can pay the ultimate price."
The teenager who supplied MDMA to Emily and her friends avoided jail earlier this month.
Luke Villars, 18, of High Drive in New Malden, admitted four counts of supplying a Class A drug but was given a year in prison suspended for two years at Woolwich Crown Court on February 9.
