A Friend just tried something out that could prove interesting, i thought id share.
My buddy was making up some 1:1 Changa with a herbal smoking blend and fairy dust. To this she added 80g worth of caapi alkaloids extracted using IPA.

Once the herbs and fairy dust were added and chopped and mixed and chopped, she realized there was some residual ipa/caapi alk goo in the dish that wouldn't absorb into the wet herbs.

To this dish wet with IPA and caapi alks she added 1 gram of fairy dust, chopped and mixed it around.
The result took on the beautiful green color of the caapi alks.

Apparently the amount of green caapi alks looked like it could have a significant affect on the spice's effects but my friend couldn't comment because she hasn't tried the stuff yet.

This is like changa minus the herbs.

Edit: Regardless of not having tried this stuff, i wonder what affect it would have using freebase caapi alks rather then raw IPA extracts.

A Freebase mixture of caapi and spice... hmmm?
