How to Test a DMT Cart

In our last deep dive on DMT cart testing, we delved into the differences in testing DMT vape carts, versus testing DMT powder.

We determined that DMT vape carts can—and should—be tested with reagents, in order to confirm the substance present in your vape cart. However, the color change reactions with DMT vape liquid will differ slightly, compared to testing freebase DMT or DMT HCl. Specifically, for testing a DMT vape, we opt for our LSD Spot Kit Package, instead of our DMT Spot Kit Package, which was designed for testing standard forms of DMT.

How to Extract DMT from a Vape Cart

In our last post, we emphasized that when testing a DMT cart, one of the most important steps is to drop vape liquid out of the cartridge to test it, and to not drop any test kit liquid into the cartridge itself. This is very important—dropping test kit liquid into your DMT cart will make your liquid toxic to consume!

We wanted to expand upon the steps for extracting liquid from a vape cart, especially with carts that may not present an obvious way to access the vape liquid.

Extract DMT from a Cart with a Mouthpiece That Unscrews

To extract the DMT vape liquid, typically, the mouthpiece can be removed from the vape pen, the vial can be unscrewed, and a few drops will drop out of the end when held upside down. Or, you can use a syringe to pull liquid from the cart. Some recommend heating the cartridge or the syringe slightly to help the liquid flow more easily. You can use a hair dryer to warm the cartridge, or place the cart in an airtight plastic bag and submerge it in warm water.

Extract DMT from a Disposable Cart (or One That Does Not Unscrew Easily)

We had previously written that if the vial cannot be unscrewed, then it will not be possible to test the liquid. However, DMT vapes that are disposable, do not have a way to easily access the liquid, or are not intended to be refilled, often still have a way to be opened (and the liquid extracted). We have included those steps below.

1. Gently pull the DMT cart to separate it from the bottom of the vape pen.
2. Carefully wedge a flat tweezer or knife edge between the black mouthpiece and the clear plastic cart. Gently pry the black mouthpiece off of the cart. Be slow, and wiggle the piece until it comes off.
3. Once the mouthpiece has been removed, gently pull the white rubber guard to remove it. Be careful—this is what holds the e-liquid in, so removing this piece too quickly could result in spilling the liquid.
4. Once the rubber guard has been removed, use a small spoon to collect a few drops of the liquid, and place the drops into two wells of a testing platform (or in two test tubes). Perform the test with the DMT Vape Spot Kit Package (also known as the LSD Spot Kit Package).
