Quote:So what's the deal? Does anyone know what I'm referring to? Are these cartridges real? If so, do they work well? Why is their mention so limited? Has the technique evolved since 2010-2014, or is this all hogwash?
Yes, cartridges are real. This was easier to answer than the "entities are real?" question.
DMT freebase is not very soluble in VG, but it is quite soluble in PG. So, yes, it's usually soluble in vape juices, but the solubility point depends on the exact PG/VG mixture and temperature. 1 ml of PG can hold more than 2g of DMT in solution, so you can make a very potent e-juice.
I don't think there have been many recent innovations in this department, except for the one downwardsfromzero mentioned (DMT citrate instead of freebase).
Carts work well, but they have their cons over other methods. You can vape e-juice from a sub-ohm atomizer instead of carts, and these work a bit better (they can atomize a higher amount of liquid at once, and they don't seem to have that many problems with clogged coils).
If you're about to make one yourself, I would suggest trying the famous 1:1 ratio (1g DMT to 1ml PG) if you're gonna use the liquid in a cart. If you're gonna try the liquid in a sub-ohm atomizer, a milder 1:4 ratio would be enough. I haven't tried the DMT citrate thing, but that could be interesting.
Or forget about carts, and take a look into the e-mesh ROA, because it's vastly superior
Vapes are cool for a longer session, though, it's nice to have both.
