I am not sure why you seem so angry or why you didn't get my analogy. If he goes to a Dr., any Dr. and says that something bad happens when he vapes and only when he vapes the Dr. is going to tell him to stop vaping and move on to the next patient. No Dr. is going to try to making vaping more enjoyable for someone.
Now if he is wheezing even when not vaping, that is a completely different story.
I am not angry although I am annoyed that you feel I need you to correct or disagree with my opinion which I offered to the OP. I am not interested in debating anything with you but you tell the OP to go to an ENT when I suggested a Pulmonary Specialist due to the symptoms they listed. You have your opinion and I have mine and I do not have any reason to debate anything. My interest was in trying to help the OP.
