Hi FC! Smoke is -hands down- way worst than vapor, no doubt about it: it gives me sore throat, I get black phlegm and lots of coughs. After a while, smoking kinda numbs my cough reaction so I cough less and less (nice bong hits are smoother, I agree with that). Vaporizing is way better in my opinion: no black phlegm, little coughs, no smoke smell. However, I think there's one thing one should consider when discussing the healthy aspects of vapor: temperature. So I started to worry about the side effects of inhaling hot vapor, mainly because: -We vaporize for years. -Each session lasts around ten to twenty minutes depending of the vaporizer (things like VapCaps give shorter sessions I think). -Unless we use glass attachments, the vapor path is relatively short and warm/hot. Basically, we are sipping hot vapor out of a "hot pipe" (short glass, plastic, metal, whatever) in our mouths for ten minutes or more, several times a day for years. In my experience, high temperatures give me a sore throat after a while, so much that, sometimes, I cannot stand the hot vapor anymore. I have an Arizer Air and even at low temperatures (blue, white or even green) I find myself wanting to plug some king of glass bong to the vaporizer just to make the vapor more bearable (which I do btw and the sore throat disappears). If I vaporize two to three times a day (without bongs, just the default mouth piece of the AA), for days, I start to develop a sore throat and a overall dry mouth due to the hot vapor. So I started to google trying to find the possible side effects of this and found that, in general, having hot things in our mouths for a relatively long time, day after day, for years... has been, in some studies, linked to things like mouth cancer. For example, warm/hot pipes in "mate" (tea like herb from south america) drinkers' mouth have been associated with a higher risk of getting some kind of mouth cancer. Apparently, people tend to rest the warm pipe in their mouths while drinking the hot beverage (I lost the links, sorry, but you can google it). I would like us to discuss this topic if you please. I think it's important.
