Well, I took the plunge and made some Changa with Caapi leaf.
I took about 5 grams of Caapi, made it into a tea, strained, dried, and then added that to 1 gram of Caapi leaf and 1 gram of spice, so almost a 1:1.
80mgs of this was put into my friends water bong and all was consumed in 2 hits, most of it on the first hit.
I was expecting a mild adventure into hyperspace with only 40mgs of spice.... I was apparently wrong. It took me deep, quite deep in fact, but did not increase the duration. The after effects lasted almost an hour though, and the afterglow from it feels very Aya like. The visuals were not much different than normal spice though. It was not quite like MAO inhibited voyaging...no warm enveloping blankets of love, no overwhelming euphoria, but it was very nice.
Surprisingly, the enhanced leaf was some of the smoothest I have smoked. It was quite nice in fact, and I have to say I enjoy it more than blue lotus.
3 other seekers enjoyed the changa as well, all noting some subtle qualities they have not observed before with pure spice.
Thank you for making me interested in this....
