I wanted to start a friendly discussion about a question I have been pondering lately. I have been told that the heat from smoking destroys all the crap that ends up in the finished product. I'm talking stuff like dust, PM spores, any small contaminants that will go airborne. Yes I am aware you destroy cannabinoids too. Even the best grower growing the best organic method possible can't have a completely clean product. You are always subject to the environment. After reading that even dust will pass through your waterpipe in air bubbles made me wonder, does vaping at these temps we use not destroy potentially bad compounds that combustion would incinerate? Rather just carry them through in the warm vapor path? This is just speculation of course and I would want to know what temps the main carcinogens and contaminants vape off at. This whole idea was brought to my attention only because my my last batch was subject to slight powdery mildew on some buds due to a crack in the seal of room. You can cut off all visible parts of the PM and no one could ever tell some of the crop had some, trust me, you can't tell. Most growers will just rip off the calyxses/leaves with PM and smoke/sell the rest. The argument is the temps from lighting the bowl incinerate the spores and no health problems have ever been noticed. Problem is I don't know any growers that vape, and the conversation yesterday got me wondering. Is one downside to vaping the fact that it potentially could not destroy these common contaminants? So before I'm attacked I'll go ahead and say I'm all for vapor, I know it's healthier than combustion, not here to argue that. I just wanted to see what you smart people have to add on the subject of dust and debree not getting destroyed by vaporization, TRUE or FALSE, how can we find out? Or am I just paranoid?
