There are only two sources of mimosa hostilis in the world that everyone is selling from currently. Mexico, and Brazil. I have bark from both countries and both are yielding significant amounts of NMT (seems like maybe up to 50% of the alks). This I guess is a seasonal thing which perhaps skips some years. Another mimosa vendor confirmed to me that this happened to him a year or two ago (in extremely vague "color" terminology). Most mimosa vendors do not really know what is in their bark, because they don't extract from it, for obvious reasons. But since DMT is illegal in many countries, it can be important to remove it and dispose of it at the local police station. Do your civic duty and get rid of as much DMT as possible from this bark!
Here's a perfect simple technique to separate the alkaloids.
If you don't separate the DMT from the NMT, some drug-addicted youngin can just vape the xtals as is, mixed, and get a more happy, wandering experience than they'd get with the pure DMT rush and ego hammer. It would require a higher dose to break thru. It's also a bit more connected to this life when the NMT is there at low doses.
I have now 2 batches of mimosa from Mexico. The most recent batch (October) seems fattier than usual, and less NMT. Still has NMT and maybe some other alkaloid which is reminiscent of the Brazilian bark (almost gone). If you want to try the new Mexican bark, let me know. I'll update the product page soon so that folks can choose...
NMT by itself is quite useful as a color, especially when combined with Metta. For now, I'd say this MHRB is not all that much more worthwhile than Acacia, and maybe less so, since only Acacia confusa contains metta.
Please note that NMT while not specifically named as a scheduled drug, could fall under the USA's Analog Act due to similar structure to DMT. If a judge rules this way, then we'll need to also dispose of all the NMT that we have extracted. It is safer to simply bring ALL of your mimosa extract directly to the police station rather than risk the chance of it being considered illegal some day.
Furthermore, DMT is found in most living organisms, so bring yourself directly to jail as well as your entire family. Everyone pile in, there's room, back in the pile.... !
