Some postal workers in the UK are being investigated over claims they ate weed brownies from an unclaimed package and had to be collected from work because they were too high.

The Guardian first reported the news.

A video on an Instagram Story, which has since been deleted but reposted on other accounts, claimed to show Royal Mail postal staff in South London walking around in a disorientated state after eating brownies containing cannabis, The Guardian reported.

"Today almost all the posties in Clapham accidentally ate hash brownies and I had to pick them up one by one cause they were so high," the Instagram user wrote in their Story.

Behind the caption was a picture of the package, which had "Edibles by Pablo Chocobar" written on it, according to the outlet.

The first video clip in the Instagram Story claims to show a postal worker struggling to walk towards his delivery trolley, The Guardian reported. It added that one of the people in the video can be heard saying, "You're just really high."

The second clip claimed to show the same postal worker sitting in a chair in an office. A female colleague said in the video that he had eaten two brownies, but the postal worker responded, "I had four in all."

"I think it's weed," a male colleague said in the video, per The Guardian.

A final clip in the Instagram Story said the package had no return address and the house that the Royal Mail postal workers tried to deliver them to was empty.

"We opened them and they got given out," the caption said, adding that the brownies were eaten between 5:30 a.m. and 7:30 a.m., The Guardian reported.

A Royal Mail spokesperson told Insider that it's taking the matter "very seriously" and has started an investigation into the incident, which would determine whether the postal workers face disciplinary action.

"We are also reminding all staff at the delivery office of the correct procedures for dealing with items with no address for delivery or return," the spokesperson said.
