Malia Obama at the festival.

Malia Obama has been accused of smoking dagga after a video of her puffing on a suspicious cigarette was released on a tabloid site

The Daily Mail reports that the president's eldest daughter was seen inhaling from the cigarette during the Lollapalooza music festival in Chicago.

The brief clip was published by Radar, which quoted an eyewitness as saying the 18-year-old was smoking marijuana.

Marijuana was recently decriminalised in Illinois - the state where she allegedly smoked. Decriminalisation means smoking marijuana is still illegal, but the punishment and penalties are lenient, the Daily Mail said.

We take a look at reactions on Twitter.
