haha to each his own.
there's no right or wrong reason for doing psychedelics.
come on dex, more open-mind less hostility.
you know the drill.

me personally, I do them for a combination of fun and enlightenment.
I almost always learn something about the world when I trip, whether it's about myself or anyone else, or even people in general. I enjoy the solitude of tripping, and value that more than any other part of a trip. If I can't even get a minute or two for my own personal discovery, then the trip isn't complete. That's just me though, and I know plenty of others who do it just for "fun", and that's fine by me, but taking some alone time while tripping is definitely recommended.

I also like how tripping removes any sort of restraints on my mind, and it goes whereever the wind takes it, which I guess sort of goes with learning things about myself and the world.
