After the lead singer of Italy's contest-winning band was accused of doing drugs prior to the performance, the EBU posted a message clearing David of wrongdoing:
“Following allegations of drug use in the Green Room of the Eurovision Song Contest Grand Final on Saturday 22 May, the European Broadcasting Union (EBU), as requested by the Italian delegation, has conducted a thorough review of the facts, including checking all available footage. A drug test was also voluntarily undertaken earlier today by the lead singer of the band Måneskin which has returned a negative result seen by the EBU."
"No drug use took place in the Green Room and we consider the matter closed."
