DMT behaves nothing like MJ when vaporized:

Vaporized DMT produces an incredible amount of “smoke”. Smoking technique is very important, regardless of the type of device being used.

When DMT is liquefied, it will migrate away from the heat source. So if it is vaporized on aluminum over a bottle, much of it will run to the underside of the aluminum and the edges of the bottle. Once away from the heat, it just sits there and doesn’t get vaporized.

---- Much of the DMT may have been lost in this way.

Vaporized DMT rapidly condenses. Anyone with a glass vaporizer (such as the GVG) can see this firsthand. A large volume of very dense DMT vapor will immediately begin condensing on the inner walls of a jar/bottle. The more dense the vapor, the more rapidly it will condense.

---- More DMT is lost due to condensation.

Very dense DMT vapor is not easy to hold in one’s lungs. It is necessary to hold the vapor in the lungs for a relatively long period of time (20-30 seconds) in order to fully absorb it. If a large amount of vapor is inhaled and then quickly exhaled, much of the DMT is lost.

---- Depending on how brief the DMT vapor is held in the lungs, much can be lost during exhalation.

Keep in mind that the OP didn’t weigh his dose. He said it was about half a level teaspoonful. The density of DMT freebase can vary by at least a factor of 3, probably more. And even if the dose was carefully and accurately measured, the size of a smoked dose is ALWAYS less than the amount absorbed into the bloodstream.

The effects of a normal dose of DMT can be extreme, and to someone who isn’t familiar with the “normal” effects, such a dose might seem like an overdose, or even like a dose that’s “way more than any other documented cases”.
