“Have a shot of tequila first, cheer up!” Shahriyar tells guests gathered at his luxury apartment in Tehran.

His girlfriend, Shima, said they party every weekend.

“Shahriyar has one rule: bring your booze! We drink until morning,” she told Reuters on a FaceTime call, as lights flashed to rap music in the background.

Despite the ban on alcohol and frequent police raids, drinking in Iran is widespread, especially among the wealthy. Because the Shiite-dominated Muslim state has no discotheques or nightclubs, it all takes place at home, behind closed doors.

Some of the alcohol is smuggled in, but many resourceful Iranians make their own.
