ahhh, well, I havent tried Mdma (im old, so I dont know anyone who would have it) but shroom experience to me can be quite varied.  I will do my homework on cacti, but Im more then a bit intrigued, and thats usually when I start to seek samples

Salvia is wild and Ive done some work there, Quick story:

I actually shared some with a very old ex-hard core addict just today,  I tried my best to prepare him, but sometimes Old dopers think they already have seen it all. well Long story short: He had what exclaimed was his most intense ,profound and frightening experience with salvia today , one big bonger of 10x in one toke.

Now this guy is hardcore ,in his 60's and has done it all, looks like he has been thru the mill, ex crack head, ex Meth, ex EVERYTHING -literally.  he still drinks, but hey we all need a lil something heh?

He told me when he exhaled , and of course said "I dont feel anything", that instantly while looking at me, I turned into a Giant green leaf , with dozens of snake like twisting branches, at the end of each branch was my eye, and each eye had a beard like mine (LOL that one cracked me up)  and that I looked upon him like a great deity as the world around him swirled into chaos and his molecules were ripped from his chest and he expanded into the cosmos.

I said sounds like you might have met a entity, were you expecting that?

he looked at me , like someone who just was Brought to their knees and humbled and said, "No , I was expecting a Fire cracker, but you gave me a Nuclear bomb"

Powerful stuff that Salvia 

Nice to meet and greet my friend ~ Safe Journeys
