Is it bad to chew nicotine gum all the time?

Is it really wise to constantly chew nicotine gum? On one hand, it may help curb nicotine cravings for those trying to quit smoking, but on the other, could it potentially lead to addiction or other health concerns? I'm curious about the potential long-term effects of regularly consuming nicotine gum, especially for those who are not actively trying to quit smoking. Is it SAFE to chew nicotine gum as a habit, or should it be limited to specific circumstances?
