Thanks for that post panasonic. It just proves my point that blowing clouds is not the best for getting the most thc into your body. The paper showed only 6-8mg being absorbed out of 20mg, which is small. The reason is how we view inhaling vapor, and extracting it. We still use cannabis the same way we did when we smoked, but this shouldn't be done for maximum effect, especially for medical patients. The best way is to load a small bowl, let the heat extract the cannabinoids properly(this is best done with a slow, consistent inhale with most vaporizers), inhale the vapor first, then inhale fresh air for at least 20 seconds(You want more fresh air in your lungs then vapor) that will thin out the vapor as much as possible to allow the alveoli to absorb as much vapor as it can, while also making use of it in the body, due to high oxygen activating the parasympathetic nervous system which process nutrients you take in, builds up the body, and heal it. High oxygen intake allows this to happen. You may not blow a thick cloud, but you will get a potent effect off of a small bowl. People forget that vaporizing is so concentrated, you need less herb then you would need if you smoked to get a stronger effect.
I wonder how they loaded the bowl of the volcano as this can effect temperature accuracy big time. Herb not ground up well , and tightly packed, will lower the heat inside the bowl, needing time to get the temperature up to the set temperature. If they used liquids or oils this will effect it even bigger because the bigger the oil, the more heat is needed as it congeals when heated up. I also wonder how many times d you use certain bags.id they fill the bag, as multiple fillings are needed to extract all of the thc if
I also liked how it showed thca still being in the vapor. This goes against what many people are saying as far as heat is all that is needed to convert thca to thc. The best way to do this conversion is to start low then go high, this gives the conversion time to to take place. By the time you get to the high temperatures to extract thc, you will be boiling off all of the thc, and not just some of it, with the rest being thca. If you use flower the taste will be gone when you get to the high temperature, and may taste bad, but all you have to do to combat this is to put in just a little amount of fresh herb to cover up the bad taste. If you use a clean concentrate this doesn't need to be done as the concentrate doesn't have any plant fibers that will give a bad taste, and thc is tasteless, so going higher up will not give a bad taste.
Anyway, this is much needed info for the vaporizing community. We can make smoker tools look like childs play once we use vaporizers at their fullest potential, but we will have to be willing to change the way we do things.
