Hi, I quit smoking 11 months ago, and have been chewing 2 mg nicorette gum x10 pieces per day ever since.I am 49 yrs old male, was never a heavy smoker, and I work out regularly. I have been reading literature on long term effects of nicotine, such as increased BP, harm to dental, jaw etc. so far I feel great, with none of those symptoms. My question is should I worry and quit nicotine gum as well?
