Legal action should have been taken against restaurants found lacing food with opium to hook customers because not only does it represent a clear fraud on the consumer, it represents a significant health issue. Restaurants must be able to stand on their own merits. Not only should there be penalties, they must be significant.
Restaurants should be punished severerly for lacing their food with opium to keep more customers. Lacing their food with opium is harmful for the restaurant's customers, because the customers develop a chemical addiction that changes their brain's chemical structure. This method is a dishonest means to drawing more customers, and completely unethical.
I have never heard of any restaurant that does that. But if this is true, it should be a highly illegal activity. Children could be consuming the food with this substance, and that could be devastating for their future overall health, including their mental health. Legal action is an understatement in this case.
The restaurant owner caught lacing their noodles with opium should have been given a more harsh punishment than a simple 10-day detention. It is sickening to think that he purposely tried to get his patrons addicted to a powerful narcotic in order to make more profit. He endangered their lives and the lives of their loved ones by these actions. He should have been prosecuted like any other drug dealer in China.
