definitely. I have asthima too so I should have thought of the fact that the drugs will offset the effects of the PG. inhaled PG DOES constrict the bronchial tubes, at least in some studies. So you should be cautious of vaping directly in her vacinity. Especially with what Attypops just mentioned. The PG was used alongside the drugs... But at the very least, this thread has proven that many asthmatics do vape with little to no problems, so this is definitely promising for your daughter. You could still probably contact an allergy specialist and have her exposed by inhaling small amounts. I am thinking about allergies as opposed to asthma when I was thinking about them rubbing it on her skin.. But they can probably certainly try exposing her to the vapor. Its possible. Then you will definitively know for sure, if you find a doctor willing to conduct the test. But, you also might not want to treat your daughter like a guinea pig either. I hadn't thought of it that way. If this means anything to you... My mother does not have asthma, but when I vape in the car with her, she says she can feel it in her throat and it makes it harder for her to breath. I think a lot of it is in her head, but it might not be which is why I've completely stopped vaping around her all together. So, it is possible that our vapor could effect certain people negatively.
