Police say a funeral in the German city of Rostock ended on an involuntary drug high when mourners were accidentally served hash cake. That must have been a fun funeral!

An employee of the restaurant, where the mourners met, brought the pastry without knowing the exact ingredient list. The cake was made by the18-year-old daughter of the woman, who regularly bakes cakes for events, said a police spokesman from Rostock on Tuesday. She also helped her mom prepare cakes for the memorial service, but the mother took the wrong cake from the freezer without consulting her daughter.

Afer eating the cake, 13 guests experienced symptoms such as nausea or dizziness and needed medical treament.

“Police learned about the incident later in the evening when participants came to the police station to file a complaint,” a spokesman said. The 18-year-old, who had kept the cake in the freezer for her own use, was found guilty of negligent and dangerous bodily harm in 13 cases, disturbance and a violation of the Narcotics Act.
