The teenage son of musician Nick Cave fell to his death after taking the hallucinogenic drug LSD, an inquest has heard.
Arthur Cave, 15, suffered a fatal brain injury after plunging from a cliff on to the underpass of Ovingdean Gap in Brighton, East Sussex, on July 14.
The student was taken to the Royal Sussex County Hospital but died that evening.
An inquest at Woodvale Crematorium in Brighton heard that Arthur was seen "staggering" on his own moments before he fell off the cliff.
Members of the public tried to resuscitate him after he was found lying on the ground without any shoes or socks on.
Nick Cave and his wife Susie briefly walked out of the courtroom as graphic details of his injuries were read from a post-mortem examination report.
The cause of death was from "multiple traumatic injuries due to a fall from a height", the hearing was told.
During the evidence of pathologist Dr Simi George, Brighton's senior coroner Veronica Hamilton-Deeley asked: "The history you had was that LSD was used?"
Dr George replied: "Yes."
Cave, 58, is an Australian musician and songwriter, best known as lead singer of Nick Cave and the Bad Seeds, an alternative rock group formed in Melbourne in 1983.
Following Arthur's death, Cave and his wife released a short statement through Sussex Police saying: "He was our beautiful, happy, loving boy."
