I echo the sentiments above, by
@Whissmu and
@CarolKing that owning and using more than one vaporizer, definitely helps to get more out of your weed, in terms of amount used and strength of effects, but actually it is the nature of the effects which is different due to the diff vape signatures and load sizes, vaporization/extraction rates.
I have come to understand that different vapes effectively create a completely different substance in the vapor they produce if we were advanced enough to analyse this accurately we would learn so much.
I do know that using a variety of vapes keeps the experience fresher and I appreciate the effects more. I also am constantly mixing and matching strains/phenos in a totally random basis. Not like "right, I'll have Think Different pheno 2 plant today..." its more like I grind up a strain, have some sort of load in some vape, and then I might do a random switch to any other strain/pheno, and even another vape.
So there is always flexibility, fluidity and options between strains and vapes.
If I was only using one vaporizer, Im sure I would use more weed. I get used to the hit and signature and it can be a little more mundane.
I actually find having multiple vapes to be as useful if not more useful than having multiple strains, when it comes to tolerance.
But it is not a straightforward physical thing at all in this sense, more about consciousness, perception and just the ride you take. Cycle gently? Speed in your Ferrari? Cruise in your convertible?
Or all of those in any order, you decide.
