This is a big deal.
I can't talk anyone into or away from experimentation with psychedelic substances. If you've given this a great deal of thought, and still feel that you absolutely need to try walking down that path, please heed these rules.
Stick to the natural kind .To put a fine point on it, because of our flawed nature, man-made psychedelics are imperfect, have more negative side-effects, and do more damage to our body and mind.
I say this with nearly 100% certainty... 3 reasons: I am a flawed human being; nothing is statistically absolute; and for the undeniable truth that no two people have exactly the same sort of experience. To put this another way, our individuality is the keystone. That is the crux of the matter at hand.
Finally, your experience will affect you immensely, will affect your perception of the nature of consciousness, for the rest of your existence. I highly recommend that you do this with a close friend whom has experience with natural psychedelics. That way, he or she can guide you through the experience. Next, seek out that good friend afterward. Talk through what happened during your journey. Recount everything with as great of detail as you can. Then have he or she recount their journey. Finally, compare the two journeys in as much depth as is humanly possible.
That is all that I can say, other than do some of your own research before the journey. That is imperative, so that you don't go into the experience blindly, with your mind completely overwhelmed from being unprepared. Treat it with a great amount of humility; it deserves your full attention and your upmost respect. Such is its nature.
