Restaurants in China caught adding opium to food to hook customers

35 restaurants across China have been found illegally using opium as seasoning in their food, Chinese state officials say.

Five restaurants are being prosecuted over the findings, whilst 30 more are under investigation, according to the China Food and Drug Administration.

It is unclear how the opium came to enter the food, however, previous cases in China have seen chefs try to ‘hook’ customers on their food through use of the narcotic which can cause serious addiction.

At least they aren't trying to serve up cat or dog.
