Psychedelics are merely tools. Just as coffee is a means to an end when you need to stay awake and work, so psychedelics are a means to an end when you are trying to figure yourself and the world out on an emotional level. Just eating them and expecting benefit is fallacious. It's like buying a hammer and being surprised that you don't suddenly have a shed - you need to pick the tool up, apply it to the relevant things and be skilled in how you do so.
Personally, I see psychedelics as a compliment to meditation. I would not recommend that anyone trip before they have a solid foundation. If your mind wanders easily, if you cannot look inside yourself, if you cannot sit in silence and be OK with it then you are not ready. Meditate regularly for a year first and then you will be able to reap some real benefit from tripping. Don't pick up a hammer before you know what a nail is. You might hit the wrong thing and end up with a hole in the wall.
