Thanks, Stosh, Vapor Eyes Er, and Caridwen - I'm off to do some more reading.
Ahall, it never occurred to me that flavors could be the problem! I assumed it had to be the fluid type. It sounds like you've become more sensitive to certain flavors over time? Is there an obvious difference in your asthma when vaping compared to smoking?
That is for sure. I have never been able to narrow down the flavors that do it to me as they seem random. But then again. Many liquid have flavorings in them that you would never know by the taste. So I try them and the second I have an issue I pass the liquid on to a friend
Vaping flavors that I don't have a reaction like that to gives me no asthma issues at all. Even chain vaping. Even being around smoke sends me to an inhaler or nebulizer every time.
I don't think I got more sensitive over time although that might be true. I think I was just not wanting to admit what the issue was since it was my favorite flavor lol. Took a while to put it together.
To rule out the PG and/ or the VG you could buy small bottles of USP Grade from the pharmacy and try vaping each one separately without nicotine and see how you react. They generally don't ask about the PG but if they do just tell them you're making non allergenic soap or candles.
BTW, the reason some VG juices are thinner is because vendor thins with distilled water. You can do that yourself as well, one or two droppers of DT in a bottle of juice, til you like the consistency. Make sure water is distilled, and of course, sterile.
Mike makes great juice. Keep in mind that a lot of fruit flavors can crack a clearo tank, thus be irritating to lungs. Esp anything in citrus family but have seen it with other fruits. Likewise, cinnamon, etc.I also used one of the Hawaii flavors from Roar.
I don't have asthma and can't vape most fruits.
You all are really amazing! I can't believe how much you know and I'm so appreciative of your willingness to help!!
