I love fire cured tobacco. Fire curing adds so much to tobacco. There appear to be quite a few tobaccos that are fire cured. And I gather that there are different woods and methods of fire curing too. My favorite is what people call fire cured kentucky. But I have come to learn that there is a lot of variation within that category. Lately I am particularly enjoying the African style "kentucky." I find that it has less of the food-like flavor of the American style kentucky. It is much more earthy, herbal, and incense like. Nothing at all like BBQ.
I think that a high alkaline smoke is what makes a tobacco feel rough on the nasal passages. In my experience fire cured tobaccos tend to be more alkaline.
I am very skeptical when people say that tobacco or smoke are a problem for their allergies. I am allergic to so many things that even my allergist was surprised by my test results. I am allergic to basically every environmental allergen and to countless foods. My food allergies are severe and many can be lethal to me. My environmental allergies (pollen, mold, dust, dander, etc) are also quite severe enough that they often interfere with daily life. I am allergic to enough things that no matter the season I am always under assault. As a child I was asthmatic and was at times hospitalized for it.
Smoking is not a problem for me. In fact it appears to even help my allergy symptoms at times. Tobacco, and specifically nicotine is medicinal. Nobody will convince me otherwise. I would bet that most people who cite their allergies when complaining about smokers just dislike smoke and are using their allergies as an excuse.
Fire cured tobaccos are basically smoked tobacco right? Are smoked meats more harmful to our health than regular meats? Maybe, but I don't think the harm is significantly higher, and even it if was I don't think I care. I will continue to smoke what I like and anyone who has a problem with it is free to find substitute company. In my experience people (even anti-smokers) tolerate my smoking when they take a liking to me.
