Tributes to Bradley Cockel after Witham drug death
A 19-year-old man who died on Saturday after he is thought to have taken drugs was "sensible" and had the "brightest of futures", his family has said.
Bradley Cockel, from Braintree, Essex, was found dead in a flat in Witham.
Police believe he had taken a "poorly produced" type of LSD along with two other men who were taken to hospital.
A post-mortem examination proved inconclusive and four people have been arrested in connection with the investigation, police said.
Essex Police said further tests would be carried out to determine the cause of Mr Cockel's death.
Mr Cockel's parents said they hoped their son's death would "serve as a lesson to anyone who thinks it is safe to experiment with drugs".
'Not worth it'
The men are believed to have taken 2C-E, a white crystal powder which can have a hallucinogenic effect.
Police said the drug had been produced by criminals with "no regard for the lives of their customers".
Mr Cockel's parents added: "If anyone could see or feel the pain that our family is suffering, and will continue to suffer, then they would realise that it is a risk that is not worth taking."
They described Mr Cockel as a "loving and beautiful son and brother" who worked hard in the family business.
The two other men who were taken to Broomfield Hospital were later released.
