Not saying nothing bad about anything and I don’t it to seem that way. Yes everything was the same. It was 6mg. im not even saying it was the juice. It could have gone bad I’m not sure.
bad juice will taste off but it's not anymore dangerous than newly mixed ejuce.
I don't think your trying to make vaping look bad, it's a legitimate question.
there is a lung disease called EVALI that came about as a result of people vaping CBD oil, which had non-water soluble products in it that was in fact dangerous.
but regular nicotine ejuice products don't have those types of ingredients (everything in ejuice is water soluble), and won't harm your lungs, at least not such as your describing your issues to be.
What your describing doesn't seem related to what your vaping... I don't think an allergic reaction to new juice would cause chest pain etc.
It does sound like you have some underlying health issues, and I'm glad you've made an appointment with your physician.
I wish you the best going forward..
