Man, 25, died at Royal Welsh showground after suspected drug overdose

Dewi Aeron Evans, aged 25, was found dead on 18 July at the Royal Welsh showground in Builth Wells following a suspected drug overdose. In a separate incident, a coroner determined that Jack Burton died from drug toxicity. The medical findings indicate that the act of quitting smoking caused the levels of clozapine in Burton's blood to reach toxic proportions, leading to his death. Both cases highlight fatal outcomes associated with pharmaceutical and substance toxicity.
