Reading the tongue-in-cheek comments (LOL) I just had to comment. I had allergies so bad I had to take shots three times a week for months and was constantly developing new ones so quite shots and just suffered. I took various prescription and over-the-counter antihistamines and mucinex-like stuff every day. I smoked for 58 years and 2 PAD the last 5 of those. Since lowering my smokes to 3 or 4 a day (if that) and chain vaping all my symptoms are gone except for a recent 2-day hayfever bout with sniffles when levels were really high. I still react to all molds but that's really a different category entirely. My theory is that my immune system was over working, and therefore weakened, all the time from something I'm allergic to in smokes.. could even be tobacco itself but I did not test positive for nicotine allergy. At any rate, its a whole new world not having allergy symptoms. Of course I still have the allergies, they never go away, but I'm symptom free due to a stronger immune system (I think) and don't have to take pills anymore. I didn't start vaping even thinking about my allergies so this has been quite a bonus for me.
