Credit:EBU EBU said it came to the conclusion after it reviewed all the available footage of the TV broadcast on Saturday night and saw the negative results of Maneskin singer Damiano Davidâs voluntarily drug test. Rumours had swirled on social media â and were raised at a Eurovision news conference â that David had snorted cocaine when he was seen leaning awkwardly over a table during the live TV broadcast. David immediately rejected the claim, saying he never uses drugs and that he was leaning over because his guitarist had broken a glass.
