I remember reading as a lad that Syrian Rue and Caapi could be somewhat enjoyable on their own.
I've had a few doses without any psychedelics on top of it, and it makes colors brighter, is somewhat euphoric, and enjoyable.. usually relaxing in some aspects.
I've heard good things about smoking it, so I'm trying an experiment. I took 5 grams of it, mashed it up with a hammer, soaked it and agitated it in isopropyl alcohol.. I'm evaporating it now, and it's very yellowish brown.
Harmala alkaloids glow under a black light, wish I had one.
I figure scraping up some of this goo and smoking it will be more effective than the seeds, although a freebase for would be more effective.. I don't feel like basifying shit though.
Smoking a bowl of the seeds was harsh but it was about a gram of them, and I did notice effects.
