Schiphol airport police have warned travellers not to eat bars of chocolate named Noir de Noir which are believed to be circulating at the airport. Police were alerted when a tramp became unwell after eating the chocolate and reported having visions. Investigations have shown that the chocolate was contaminated with psilocine, the same hallucinogen found in psychadelic mushrooms.

“We suspect the chocolate was left behind by a passenger who decided not to take it on board,” said a spokesman. The chocolate’s packaging is black, brown and gold with the text Noir de Noir.
