Recently I have obtained half a gram of DMT freebase and I have been doing assays with this substance for two months. Also, I sent a sample to a lab for analysis (NMR). I have received the results some days ago, this is the list of compounds found in the sample:

DMT: 55.5%
NMT: 9.8%
CaSO4·2H2O (gypsum): 34.7%

I am a bit shocked with the gypsum issue. I am not sure of how interpret the presence of this substance. At first I thought I had been cheated and the gypsum was used by the dealer to cut the dmt. But also I am thinking that it could have something to be with the freebase form of the substance. Maybe one has to add some basic chemical like gypsum to make the DMT freebase, and it reacts with the DMT to form the freebase molecule? Then, when the NMR analysis is done, the molecules break apart and one obtains DMT and gypsum as separate substances. Does this make any sense? My knowledge of chemistry is very limited, so please if someone can confirm any of my especulations (cheat or normal chemistry) that would be very useful for me.

No that does not make sense.

Odds are there is gypsum in there and you have been tricked.

That said..the DMT-nexus does not support the buying/selling of DMT, and there is no talk here of either actions. I would suggest you learn extraction from plants for yourself so you can always be sure of what you are ingesting.

Please be careful.

I would suggest you at least look into teks to clean and re-crystalize what you have before you think about ingesting it.

Many thanks, Jamie, your response is very useful for me. Sorry for the misuse of the forum topic, I had though there would be no problem if I did not mention the source explicitly. But I will be more careful in the future
I am not going to smoke it once known that it has gypsum, but I will investigate for the cleaning teks, it will be an interesting experience before I decide to extract my own spice.

Very interesting... sucks you've been smoking gypsum! Good thing you had that test done, I didn't know that was even an option for people. How do you go about getting an NMR analysis?

I don't know much about chemistry either but you do need an alkaline compound during an extraction to freebase the dmt. I've never heard of using gypsum for the purpose, although it is alkaline. Maybe somehow a chunk of drywall landed in the extraction unknowingly and got crystallized with the dmt? Not sure if that's possible, especially with all the unknowns of your situation.

Gypsum is inert, I mean non toxic, and doesn't melt or evaporate at temperatures needed to vaporize spice.

You can smoalk it in machine, bong or GVG, you can't inhale it that way.

But next time, make your own spice. You'll see how much better that is. ^.^

Peace and love.

Well, there is a risk reduction organization here in the Basque Country that does these analysis, using the services of a professional lab, but I am not sure if I can say the name here in the forum. As far as I know they do the best analysis you can get in Europe.




Thanks oversoul. Doing my own extracts is my dream, but I have to study this issue a bit deeper yet. I must say that you people are inspiring me a lot in this forum, and I am feeling more and more greedy for getting on with it

inert or not, don't smoke gypsum. It's so easy to the clean the DMT and re-crystalize it. Might as well do it right.

Gypsum has no place in DMT. I can not see how it could be useful in an extraction, nor how it could somehow form as a side reaction. Especially the fact that about half of the product was gypsum makes it obvious that the DMT was simply cut with gypsum. Clearly someone tried to make a quick buck by selling overpriced gypsum.
