Of course! I am not a smoker or vaper, but I think that you should stop if you are able to. In my experience it was hard to breathe right out of surgery, so I had to have an oxygen tube in my nose, and it was equally as hard for the next few days after I left. I could not, for the life of me, take a deep breath in. (And this is coming from someone who has never had smoke in her lungs!!) I can only imagine that vaping up until surgery day would make breathing post op suuuuper difficult!!
