I'm a chronic pain patient, and my pain management doctor knows I vape. He hasn't had any concerns.
And I was on antibiotics for 20 days right after Christmas, and told that doctor I vape (had to go to an urgent care place due to the holiday). She had no concerns either.
Don't hide things from your doctors

. They need to know everything before prescribing meds. None of them have been upset that I vape. They are glad I don't smoke anymore.
