Hey there,

It's not fair to compare Salvia to LSD. Salvia is not a very positive trip. It's messed up and very disorienting. The african tree bark drug you were referring to is probably an Ayahuasca ingredient, a DMT based psychedelic brew.

DMT freebase and Ayahuasca are very positive trips. Feelings of love and light, and contact with loving knowledgable entities. With DMT freebase, you are shot out into what we call hyperspace, a vast infinite spirt realm. It's incredible and very spiritual, very positive. The DMT trip lasts 5 to 15 minutes, but feels like thousands of years from inside. It should also be noted that the rapid come up is very pleasant, you literally feel your consciousness expand in the span of a few second.

Salvia is a bit like DMT's evil twin. It also send you out into another realm, but it's a very dark realm. There's something very functional about it. The movement in it is very disorienting. There are no feelings of love and light. There is also entity contact, and from my experience they are also knowledgeable, but they're not loving. There is no warmth, only a endless void. As you leave your body, it does not feel good. It feels like reality is disintegrating and you're falling into an abyss.

I hope that helps
