David Leslie Selman, who had schizophrenia and epilepsy, died after consuming a large amount of legal highs that adversely reacted with his prescription drugs. When he developed unusual behaviour, shaking and spasms at a public house, ambulance attendance was delayed by a miscommunication about whether the crew should stand down or stand back, and information about his condition was not passed on for reassessment of the resources needed. He later went into cardiac arrest before arriving at hospital and could not be revived; the inquest recorded multiple drug toxicity as the medical cause of death.
