The 18-year-old daughter of US President Barack Obama has been spotted smoking what many have suggested is a cannabis joint at a music festival.
Ms Obama, who set to attend Harvard next year, was at Lollapalooza in Chicago, Illinois where a video was captured of the first daughter smoking.
In the nine-second video, published by Radar Online, a young woman in the foreground danced and stuck her tongue out while Miss Obama could be seen in the background.
The US website claimed an eyewitness had smelled cannabis.
Cannabis is decriminalised in the state of Illinois and people are allowed to possess up to 10 grams of the drug.
Miss Obama missed Hillary Clinton's speech at the Democratic National Convention last month to go to the festival
Previous video had emerged of her "twerking" at the festival.
