I have been looking at post in the changa sub-forum and i have become a bit confused. But my question is, do i need pure DMT to make changa or just DMT containing plants.

Changa contains a few different alkaloids, first off 1 grams of relativley pure extracted
dmt and and aroun 100-150 harmalas extracted from B cappi or some extracted harmine from syrian rue. Once you have those two make a sald with your favorite smokable plant ads the dmt and harmalas to some IPA pour it on your herbs and wait for it to evaporate.

I think one gram of mixed herbs is the suggested amount to evap onto although I like to use a half gram more.

Do the evap in a small baking dish so once the IPA evaps, if theres any spice left, you can scrape it and not waste any. When this happens to me I scapre it up and add it to the dried changa.

Chaeck the faq and wiki too, lots of good info there!!!

generally most DMT containing plants are inactive when smoked (due to low concentrations)

a major reason of extraction is for smoking sake. due to the vast amount of plant material required to achieve desired effects, and the rate of which a persons tolerence to dmt builds, its most efficient to smoke an extract. you dont need 100 percent dmt but you need more than the 2-3% found in rootbark. you could even use an alcohol tincture to achieve atleast threshold effects (provided the spice is in salt that is weak/ freebased)

using maois will greatly increase and augment the experience, you may even achieve breakthrough experiences with low quality dmt extract (ie resin or something) if you properly ingest an maoi in some fashion
