Damn man you guys made Luchiano pull his books and reference on you guys haha. You do know that coughing is just part of the process of adrenaline rush? I mean running away from potential danger causes the flight or fight reaction and that doesn't entirely involve coughing to start your adrenaline. If density of vapors matter in how high we get from it shouldn't we also consider the herb potency? Also I think chemical reaction has a lot to do with how much higher we really get. For me, I have tried different types of vaporizers and all of them give me a different yet noticeable high but the Sublimator tops all in this century. The Sub eliminates the process of allowing vapors to cool down within a large capacity therefore restricting how much oxygen is used to extract the oils from the plant materials. By doing this you are basically taking a highly concentrated dose of THC into your respiratory system giving little time for THC to start hindering the CBD and CBN effects. If you use bags, you are more likely to feel tired after because THC begins to oxidize (bags aren't air-tight) and break down into CBD giving you a messed up feeling just like hitting a pipe. I can compare the two because it doesn't matter how many bags or bowls, you will still reach the same high at some point but the healthier option will always make your body feel better (uplifting). The Volcano cannot produce the adrenaline I need from my sativas. I feel a lot better now using the Sublimator to get that energetic, euphoric feel (if you use a lot of herb or oils) I need for work everyday.
From what I seen, the sub is mainly used.as a high temp.vaporizer. The volcano give thick vapors, although not as thick as the sub because the restriction on the subs atomizer causes the air to come into close contact with the vapor which will allow condensation as it will be cooler then the highest temperature that the heater is since the temperature dips a lot when you inhale. This will cool down the vapor from its highest temperature which will cause the vapor to slow down and stick to each other becoming bigger ultimately becoming a solid. This is why I feel you get such a high amount of reclaim oil .
To get a close effect with the volcano, you need to set it to the highest setting, use .05-.10 grams, and grind real good. You will extract everything in one bag. This has been proven already. you will get some cbn but not much since the thc will be boiled off fast, and inhaled fast. It will also have room to spread out since the bag expands, and that means less chance for the vapor to come into close contact with air. Using the volcano digital will give a quicker and more concentrated than the original since it keeps the heater to stay within 2 degrees of the chosen temperature while the analogue only stays within 9 degrees.
Btw, this close contact of vapor and air is why bongs, and whips, give more thick vapor then bags.
