Jack Watts

A video has surfaced on on social media showing Port Adelaide's Jack Watts snorting what looks to be an illegal substance off a woman's breasts at an Oktoberfest event in Germany.

However, Watts' manager Paul Conors has since revealed the white powder to be a harmless 'peppermint' mix that is legally used throughout Germany, containing menthol, sugar and glucose.

“It’s not cocaine,” Connors told the Herald Sun.

“It’s clearly a legal tobacco based powder used widely at Oktoberfest.”

It is not known when the video was taken.
