"MARIJUANA IS NOT HALLUCINAGENIC"

Yes it is.

Eat a 8th of nice resin and tell me you're not hallucinating.

I (stupidly) did this before my art exam several years ago and I was hearing lots of angel people singing and the room was vibrating the whole time. Not entirely pleasent.

[Edit]
Ta for the salvia exp. report. I'm interested in trying the stuff and youe report is more detailed and interesting than most on erowid.
