The men were not accused of selling alcohol, just drinking it.
Hojatoleslam Hassan Shariati, chief of the Khorasan provincial Justice Department told a news conference that the death sentence had been approved by the Supreme Court. All death sentences must go to the Supreme Court in Tehran for confirmation.
If the men are indeed hanged, it is believed it will be the first time in the Islamic Republic that anyone has been executed for drinking alcohol.
In 2007, a Tehran court sentenced a man to death after his fourth conviction for drinking, but the sentenced was not confirmed.
Drug use has always been very high in Iran and alcohol use is reportedly soaring. The daily Sharq has reported that police records show that 26 percent of those stopped for driving violations test positive or either drug or alcohol use.
