I have not had a problem with
vaping, but I am using zero nicotine juice.
I tried to stop smoking using the patch. I was following the program and had even stepped down to a lower mg patch. My skin started turning red in the place where the patch was. When I removed the patch there would be a red square in the exact shape of the patch. I was also experiencing the itchy skin. I called nicoderm support and they told me to stop using it. I was disappointed, I wanted to follow the program though, but they said the only recommendation they could give me was to discontinue use of their product. I had used it for a long time without issue, but then I started reacting to it. What happened is the nicotine had built up in my system to the point I started having a reaction to it, some sort of nicotine poisoning.
If it can happen with the patch, I would say a similar reaction could happen with other products that contain nicotine.
