Certainly, chest pain can be a result of nicotine overdose. They even warn you about that with nicotine patches and gum. Or, for that matter, smoking. Does anyone remember when we were kids and started smoking and got "smoke sick"? Yuck - after all these years, I still remember that feeling.But to blame it on "e-cigarettes are bad" is irresponsible, in my opinion. And I'm a nurse.
The skin irritation - wow. Who knows? A PG sensitivity perhaps? Skin irritation generally comes, as others have said, from direct contact.
This is frustrating. I'm all for monitoring and all that but come on. How is VAPING dangerous while all the other nicotine replacement products laudable?
