The “insidious mischief” of legal highs caused the accidental death of a festival goer, a coroner has found.

Jonathan Graham, 33, had consumed 5-EAPB, also named Benzo Fury, at the Brownstock Festival in Stow Maries on August 31 last year.

Coroner Caroline Beasley-Murray said she was aware there were several other deaths involving the drug.

At the time of Mr Graham’s death, 5-EAPB was a legal high but it is now under a temporary control order.

Mrs Beasley-Murray ruled he had died as the result of an accident.
