ZimZam- I have moderate to severe asthma and also seem to breathe easier up high. I think that lots of the stuff that causes most of us trouble (pollen, cats, etc.) is missing at altitude. However-it certainly is possible to get HAPE at volcano altitudes. A friend of mine had to be carried off of Mt. Whitney and straight into the hospital-they said this happens a lot there. Just don't go up too fast and you'll be fine (sea level to 12000 feet in a day gets a lot of people).
