My parents believe that having plastic in your mouth can give you cancer or be harmful. They don't mean it's harmful because of the risk of choking but they think it can make you ill. For example the cap of a bottle. Clarification please?
I don't trust plastic. When heated I know it can leach out carcinogenic chemicals. It's full of them. I don't know if just putting a bottle cap in your mouth would do it but there are no benefits from doing that. Seems like the rise of cancer coincides with the rise of plastic materials.I wonder if your parents never drink out of a plastic bottle. My suggestion is don't heat food in plastic or pour hot liquids into a plastic container to drink.
