Changa is a smoking blend. One could add any plant or herb to the mix, and users customize their recipes depending on the desired effect. Mimosa hostilis and acacia species are natural sources of DMT. Most of the changa found today will include DMT from the Mimosa hostilis. Most Australians prefer acacia.
One blend consists of only Banisteriopsis caapi leaf and DMT. Users also make changa without the ayahuasca vine, called “enhanced leaf.” However, Palmer argues that the ayahuasca vine activates the other herbs, affects the duration of the experience, and smooths out the smoke.
