I would just like to throw in my two cents and sit back. I am not truly one for debate, but I feel that Pollykok's argument is flawed and others obviously do as well.
I am not here to argue the previously set up points, but would like to possibly try to clarify other people's view points, or at least how I see them in my mind.
First, going with Pollykok's theory (heat + bowl + air), (I also would like to state this as an opinion
). If I took a big hitting vape (ie: volcano, SSV, so on) and loaded it with the same amount of herb as a perceived efficient vape (ie: MZ, PD, so on) and tested it, I think that you may get the same amount of THC and other compounds, (while heat is in the same range), but you will get it in very low vapor to air ratios because it isn't coming all at once. It is my opinion that vapor to air ratio is one of the biggest factors in getting high.
If I took a big hitter and loaded it with a full bowl, not trying to be efficient, I could get ripped easily. I attribute this to the fact that if loaded properly, the amount vapor in comparison to the amount of air in my lungs is tremendous. Since my lungs would be absorbing THC or other psychoactives more than air, it would be an easier and stronger high. On the flip side, your argument for loading a small amount into the big hitter to be efficient, would not work well in my opinion. Because there is not enough herb in the air stream, even if all the THC and psychoactives were released, the vapor to air ratio would be very small. With a small vapor to air ratio, there is more air in my lungs than vapor, therefor my lungs would absorb a high percentage of air in comparison to when the vapor to air ratio is large and I am absorbing a high percentage of THC/psychoactive compounds.
If I took the small hitter with the amount of herb it was designed for I would get a high vapor to air ratio. Each vape is designed differently and for different purposes.
When placing the appropriate amount of herb into the vaporizer, it is going to produce the best effects that the company designed it to create. (typically) The big hitters are for people who are looking to get hit hard and fast, usually seen as a party vape, not necessarily for "perceived efficiency". While the smaller vapes provide high vapor to air ratio as well as a small amount of herb.
I understand your point of view, but, each vape is going to take a certain amount of herb to get you where you want. With each vape you are going to have to use that much herb regardless.
(with hypothetical control of how potent the herb is, which Pollykok has used in previous posts) If I regularly load a big hitter with .1 grams (hypothetical and easy numbers for math) before it gets me where I want, I am going to have to use one gram regardless. If I regularly take a small hitter and load .025 grams, and it takes me 2-3 bowls to get high, that is going to be how much I will use. If I took the .1 grams and tried to use a .05 gram bowl, I would have to use 2 bowls to get what I want, even though it is the same amount of herb used in the smaller bowl to get me where I want, the vapor to air ratio will not allow me to "magically" get high off the same amount of herb in a different vaporizer.
If there is anything wrong with my logic please let me know, but that is how I perceive efficiency.
One last thing, you need to get a vape that fits your needs and then you won't have to worry about efficiency. As to Rick's analogy, I believe it is spot on. The person with the Sentra is efficiently doing what they need to do, while if a person needed to haul something (or in this case provide a powerhouse vape for a party) they would have the bigger option, allowing them to be efficient in what they need to get done.
This is the only edit- Sorry for tailing into an already "closed conversation/topic". I still believe my point of view is valid though.
