any thoughts? cancer? http://photojojo.com/store/awesomeness/smoke-drops/
smoke, vapor - you'd need to know what this actually is before drawing any conclusions. 'smoke' is a pretty vague term too - the airborne sub 10 micron particulates that cause "black lung" can occur invisibly in some combustion processes that no one would call 'smoke' -
CO2 dropped into water produces a similar looking mist.. nothing more than a water/CO2 vapour, not as convenient to carry in the poicket as this stuff, but harmless.
pop ammonia solution and hydrochloric acid together and you will get a vapor - actually it's probably what this stuff is. Mildly toxic, but certainly not carcinogenic
http://www.youtube.com/watch?v=ZYUCtpRDep4for those interested in cancers, considering the lungs are a warm, moist bag inside us that takes in every bit of dust, mould, sand, bacteria, bits of hair etc we breath in, the guy arguing lungs are a breeding ground for cancer causing diseases holds more merit to me than the guy saying some water soluble smoke may cause it (we evolved around fires, unlike every other animal)

"The most likely forecast about the future of infectious disease is that it will be very dull." At least in the developed world, infectious diseases no longer seemed very threatening. Far scarier were the diseases that the medical world said were not infectious: heart disease, cancer, diabetes, and so on. .. The infectious age is, we now know, far from over. Furthermore, it appears that many diseases we didn't think were infectious may be caused by infectious agents after all. .. "By guiding researchers down one path, Koch's postulates directed them away from alternate ones. Researchers were guided away from diseases that might have been infectious but had little chance of fulfilling the postulates." That is, just because we couldn't readily discover their cause, we rather arbitrarily decided that the so-called chronic diseases of the late twentieth century must be hereditary or environmental or "multifactorial.(ie, wee don't know) " And, Ewald contends, we have frequently been wrong.latest too is the observations that around 90% of those who contract stomach cancer has stomach uncurs.. something we now now is caused purely by bacteria.
