It doesn't matter if the doctor knows anything about vaping. Giving them a list of the things you are inhaling and asking for a reference to a pulmonary doc is prolly in order of the nth degree! If you are having shortness of breath, go to the people who specialize in lung function. But get to a dang doctor! why wait? Smoking is proven to cause COPD. I watched my non-smoking for 20+ years mother die from it. Your lungs and heart are NEVER something to mess with. If you smoked, chances are, you will be diagnosed with COPD down the road.
BTW, for the record, pg is used in albuterol, the liquid in asthma inhalers. It's also used with the mixes for nebulizers. In fact, a nebulizer is a giant vape factory! It's the exact same principle. It's also used in fast acting heart medications, but the breathing in of pg has never been shown to cause an issue. VG, is a whole nother story cause there is no story yet.
Personally, I dropped by this side because I have been having a problem and needed to sort it out with some rational talk. I have been ciggie free since 17 july 2010, and vaping like a happy little camper since then. One month ago moved to a new, less polluted climate, I am now living with 6 new animals in my life, and my allergies have gone into overdrive. I am sneezing all the time, and causing my dormant asthma to wake up and be angry. Before, I had two methods of treatment. The first being a strong, large cup of coffee and about 4 ciggies smoked in rapid order. The second, if the first didn't work was using the inhaler. I rarely used the inhaler.
So now, when I'm going into attack, I whip out the coffee and the e-cig just isn't having the same effectiveness as the regular menthol ciggie. I am getting clogged up, wheezing, and just snot production from head to toe it feels like

I am a bit of a purist, and mix my own juice. I use 100% VG, not store bought, but is kosher, USP, as well as European Union certified pure and safe. a dash of flavor, currently flavor arts white peach with a touch of menthol. My nic is FSUSA's nic which is the cleanest nic I could find on the market. My purist side has me using the CE2 cartomizer (no nasty burning polyfil, thanks)
I am just more annoyed than anything that my vape isn't doing a better job with the allergy induced asthma. The only thing I can think is the delivery of the nic is different, and may not be as effective as ciggies....I would rather die than go back to smoking ciggies. I am purely ...... that my allergies didn't go away!!! the hell!!!
I almost want to buy and mix some pure PG with a higher nice content than my usual as my "first defense" because I know PG is proven safe to be inhaled where as VG doesn't have that stamp of approval just yet.
But, thin runny PG seems to have a chemically taste to me. I hate wasting nic juice.
Or, I can just break down and use the inhaler first and be done with the whole dang issue.
Yes, I am just vocalizing at this point and would just like to hear some additional thoughts or opinions. I need some extra viewpoints in order to make sure I am on the right track, which is dealing with the new Cilia and their stupid need to be "sensitive" to stuff

)
After reading, I do realize that the Cilia in my lungs have been reborn, and allergies that I thought were gone are actually just as active as they ever were. I can take allergy pills for that, and that would prolly end the issue all together. But my homegrown asthma remedy needs a revamp. I already take pills enough, I want to keep as med free as possible,.........ok, I admit, I despise that horrible, jittery, shaky feeling I get from using my inhaler. Drives me nuts.
