"Students of the psychedelic realm know that one's expectations are a powerful determinant of the direction, content, and outcome of the experience. So, we should say at the outset that the experiences recounted here were preceded by careful preparation, where the trip was presented as a learning experience and a process of self-discovery. They all took place in safe, supportive environments. They generally did not fit the stereotypical model of teenagers dropping acid at a rock concert, looking for awesome visuals and good vibes."
