Mushrooms are great organic and imo very fitting for group activities as long as you are in a comfortable and safe environment and the activities don't demand ur social interactions. Out in public it can get really crazy and you can have experiences that rival fantasy novels and basically it's like ur walking in a dream or living up an heroic story that is as relative to your environment as it is to buddhist tales.

If you are interested in more introspective experiences it is noteworthy that salvia experiences alone have been very confusing to me. As a teacher it has been stern but gentle. Only the first time i toked salvia did it deliver a complete altering of reality that lasted more than 30 seconds. Every other time , no matter what the dose it has been sub-breaktrough or nothing at all.

Interestingly enough my salvia experiences have been bleeding over into my mushroom trips, so to speak. In the times i've used mushrooms introspectively i remember things i've picked up on salvia i forgot while sober. And i get flashbacks of salvia each time something happens on mushrooms that is associated with each other. It has given me new perspectives on both molecules and opened gateways to much bigger teachings the plants and fungi have to offer.

IMO, salvia tops them all. I have really colorfuls tube like visions (very different). And I start thinking some really wierd things like last time I smoked it I thought I turned into the table I was sitting at, and I totally forget that I am 'just on a drug'. Honestly it gets pretty scary.

Yeah...after I smoked salvia and discovered that I transformed into the couch was the first time I thought to myself, maybe I should be more careful with this substance It was pretty scary because as a couch I began to think, "well this is depressing; I'm a couch. I've got no friends - no one to talk to - I'm just a couch for people to sit on." With a moderate helping of Salvia, I'm lucky if I can remember having taken a drug, and if I do, there's a good chance that I won't figure out which one it was. You could be holding up a sign that says S-A-L-V-I-A in big colorful letters, and I would probably be like "salvia...what's that do?" because that's pretty much what happened (minus the sign) when one time I was trying to figure out what I took, and I thought to myself, "did I smoke weed?...no, weed doesn't make you feel like this...oh yeah, it was salvia...I wonder what that does (despite the madness ensuing in front of my face)."

Oh man i'd like to do experiments w psychedelics on people who never done these before

MUSHROOMS

If you care about your mind then Salvia I think - cause it's short, but strong - I have never had bad trips with her.
But if I were you I would start with DMT.
