I was flirting with COPD symptoms. though I have low BP (regardless of health status). My extremities often have low blood flow. Though only started vaping again this year, several symptoms have cleared up from vaping.
What puzzles me most is twenty somethings that talk about vaping and taste, while never having smoked. While it is better than picking up cigs, I just ask myself why, you know they have no idea how to make juice, and only go for 50mg nic salt disposables. I have some issues with those, since I purchased for the final cut off from smoking. They are not quality controlled from the different textures of vape in different but same disposables. And, some times I can chug the juice, but there seems to be no nicotine (while 35mg pod juice will set me coughing).
My belief is best to end up making own juice if have health issues (I do). You know what's in it, and hopefully, you know what's in your equipment.
