Eating a bag of cookies that had been left behind on a CFL train on Monday afternoon led to some unexpected consequences for the train's cleaning crew, as they turned out to be 'magic' cookies.

The event unfolded around midday on Monday when the cleaning crew discovered what they believed to be normal cookies left behind by a passenger on the train operated by Luxembourg's national train service.

The three cleaners decided to eat the cookies and soon started exhibiting somewhat unusual behaviour, and one of them blacked out. As the train had already left the Luxembourg Gare station at this point and the cause of their strange behaviour was unknown, the train was stopped and evacuated at the next station (Roodt-sur-Syre, to the East). The concern was that something aboard the train had affected the cleaning crew, and could affect other passengers. Police arrived at the scene and checked the train, but could not find the cause of cleaners' strange behaviour.

It was at this point that the cleaning crew told police that they had found and eaten some left behind cookies, which turned out to contain cannabis.
