An “unforgettable son” who collapsed and died on Brighton beach after taking ecstasy had undiagnosed fatty liver disease.

Lee Rebbeck, 18, of Laburnum Avenue, Hove, died shortly after collapsing outside Shooshh nightclub in Kings Road Arches, Brighton, in the early hours of Friday, August 18.

The former Blatchington Mill sixth-form student, who worked part time at the Co-op supermarket in Hangleton Road, Hove, was celebrating A-Level results with friends.

Paramedics tried to resuscitate Lee after he was discovered unconscious on the beach at about 4.30am, but he later died of cardiac arrest.

An inquest into his death heard how Lee, who planned to enrol on a civil engineering course at Northbrook College in Worthing in September, bought a gram of the class A drug MDMA, otherwise known as ecstasy, on the night of his death.

Paramedic Paul Windsor, who treated Lee at the scene that night, said he was “suspicious” Lee had taken MDMA after he recorded a body temperature of 40.8C.

Doctor Mark Howard, a pathologist at the Royal Sussex County Hospital in Brighton, said an autopsy revealed the teenager had a severe case of fatty liver disease and his liver was twice the size expected for a man of his age.

Doctor Howard said: “The problem is that the liver detoxifies things, but when it is filled with fatty cells then it is reasonable to say that Lee's ability to break down things like MDMA would have been difficult.

“The levels of MDMA Lee took are associated with sudden cardiac arrest and death but there is a chance he would not have died if his liver could break the drug down.”

Lee had previously been admitted to hospital with abdominal pains in 2013 and 2012 - but any liver condition that may have been present was not picked up.

Statements from friends revealed Lee first experimented with MDMA at a music festival in Spain in 2013.

Lee's father Simon, 50, who told The Argus Lee was an “unforgettable son” in August, said: “Lee knew drugs were my pet hate but it is too late now.”

Mother Mandy, 54, added: “I only hope his death sparks awareness to others about the dangers of drug use.”

Recording a verdict of misadventure, coroner Veronica Hamilton-Deeley said: “Lee's cause of death was cardiac arrest caused by toxicity of MDMA in an individual who had previously undiagnosed fatty liver disease.

“As ever, every time illegal drugs like MDMA are consumed it is like playing Russian roulette with your life.”
