you ask an interesting question. when used as directed for smoking cessation nicotine replacements (such as gum and patches) probably can be safely used for an indefinite period of time. however it's possible to abuse nicotine replacement products by exceeding the maximum dosage. in this case a person could cause him/herself harm over the long run. it's worth noting also that nicotine itself is kind of a 'bad actor. ' it can cause slow wound healing among many other physiological effects. it can deplete the body's vitamin c stores. anyone who uses tobacco products or uses nicotine replacement products should take a vitamin c supplement in my opinion. wishing you well!
can nicotine replacements be dangerous if taken for and extended period of time?
