Question: What is it called when you chew on things other than food? clothes, foam?

Answer: If you just chew, it's called a bad habit. \n\nIf you also eat it, it's called PICA and it is "the persistent eating of non-nutritive substances (such as paint, string, hair, animal droppings, insects, soil) for over a month. The behavior must be developmentally inappropriate and not part of a culturally sanctioned practice."\n\nI hope this helps.
