People in Iran drink 60 million litres of alcohol a year, despite it being banned in the country, according to data collected by a committee from the Ministry of Labour and Social Affairs.
The findings reveal a "crisis-like development," Rusbeh Karduni, head of the committee, told news agency ISNA on Saturday.
Both the sales and consumption of alcohol are banned in the Islamic republic. Punishment can range from heavy fines to lashings for repeat offenders.
But a recent report from the ministry found that these deterrents have little effect. The Iranian black market is filled with a wide range of alcoholic drinks, albeit at bloated prices. Many opt instead for brewing their own illegal spirits or wine at home.
