Dorge said:caapi leaf or vine?
I would advise not using caapi vine in any changa blend. It makes it hard to dose, the DMT doesnt adhere to the vine as well as leaf. Also it tastes pretty bad, woody and rather bitter. Caapi leaf can be hard to find, so if all you have is the vine you can still use it to enhance your blend with the spirit of the plant.
For 4G of changa, ex. 1g blue lotus, 1g calea, 2g DMT, I soak ~5g of vine in about 90ml of acetone for 3-5 days. Then I use the enhanced acetone to enhance my leaf blend.
I smoke out of a GVG, so it may be different for me, as ive heard many people say the vine is just fine. But as far as im concerned, trying to make the vine directly part of your blend is a mistake. It just doesnt work well.
