It depends on what chewing gum you are referring to. If the chewing gum is peppermint (for example), it should be fine. But if it is a meat chewing gum, (let's say beef? Seldom) It is not okay. Although if you do not know, it should be fine as meat chewing gums are rare. You're welcome!
Chewing gum's flavor usually lasts longer and is harder to blow a bubble - hence the "chewing" name - you're supposed to chew it. Also, bubble gum tends to have sugar in it, whereas chewing gum tends to be sugar-free.
