The Queen's Windsor Farm Shop is selling cannabis-infused energy drinks that are flying off the shelves as customers buy in bulk.
The farm shop is selling an energy drink called Trip, made from the marijuana compound cannabidiol (CBD).
Trip comes in four flavours and has been extremely popular at Her Majesty's Windsor Farm Shop.
A source told The Sun: "The drinks are quite quirky but very unusual for a farm shop — especially one run by the Queen.
