Jedna kamoska sa na tohtorocnom boome (skrze jednoho izraelskeho dealera s zevraj doooost velkym stosom banknotez) dostala do kontaktu s drug menom "changa", dost nerozvazne to hned u jazera na plazi skurila a potom si odzila za 15minut objektivneho casu a-ani-srnka-netusi-za-kolko-aeonov-subjektivneho-casu dost husty bad trip...

Nasledne googlenie a http://www.drugs-forum.com/forum/showthread.php?t=62469 odhali ze uvedena latka sa zda byt "smokable mix" MAOi a DMT:

One of the more interesting topics that came up at the 2008 Boom Festival was a "new substance" called changa (or xanga), which I had not heard of before. One British visitor described changa as a chunky brown plant-based smoking blend. He was unsure about its legality, but said it was sold "under the counter" for £20-30 ($27-40 USD) per gram in Camden headshops. He characterized it as being "opiate-like, with the teeniest creep of DMT-like effects", and said he had heard of people mixing DMT into it. He mentioned a particular quality of electricity that occurred in one's hands after smoking it, which he called "changa fingers". Later, in response to us scrawling "Got Changa?" on our booth's whiteboard, a fellow from Brighton showed us some. He said it combined DMT with a MAOI plant, which extended the DMT effect from 3-5 minutes to about 20 minutes. On viewing the changa, I noticed that it looked similar to a Banisteriopsis caapi-plus-DMT smoking blend I'd seen earlier this year in Basel. Energy Control ran TLC on a small sample, and it spotted positive for DMT. There were three other unidentified spots, one of which the EC worker speculated might be a harmala alkaloid due to its fluorescence (although without having reference standards on hand, he could not say for sure).

An Erowid contributor from Australia provided the following data: changa is largely produced in Australia, and blends vary in composition-they may contain several herbs at different concentrations, but most incorporate Banisteriopsis caapi (either leaves, or shredded stem-bark, or both) and DMT, which is usually extracted from Acacia obtusifolia. A couple of festival-goers brought out two different blends of changa for us to photograph.

Another Australian visiting the Erowid booth claimed to be the person who invented changa. He said it is generally 20% DMT by weight, sourced from Acacia obtusifolia or A. acuminata. This extract is deposited onto a smoking blend that usually contains 60% B. caapi, passion flower, mullein, and peppermint. The remaining 40% typically contains Calendula officinalis, Justicia pectoralis, Nymphaea nouchali var. caerulea (or another lily), and Turnera diffusa. He expressed that changa is best smoked from a bong, but that people commonly take 2-3 puffs from a medium-sized joint.

While these Australians were very knowledgeable, some changa dealers may not know what they are selling. For example, one buyer at Boom was told that changa is a legal blend of four herbs said to be in the "family of DMT and Salvia". In most countries, changa can't be considered legal, and none of its ingredients are in the Salvia family.

The composition of changa blends varies, but most incorporate Banisteriopsis caapi and DMT.

z toho ako uvedena skusenost moju kamaratku rozhodila je zjavne ze DMT+MAOi combo nieje nieco co by sa malo brat na lahku vahu, a pritomnost fyzickeho sprievodcu sa zda byt nutna aby sa subjekt dostal z vyssich rovin bez traumy naspat...

nastastie bol Boom tak skvela zurka s tak skvelymi ludmi ze sa z toho kamoska relativne rychlo dostala, mozno aj vdaka tomu ze sa nebala o svojom badtripe otvorene hovorit a aspon tak svoj zazitok post hoc, a za pomoci okolitej ceskoslovenskej bandy, konfrontovat...
