If it is true that experiences involving altered states of consciousness have historically been confined to a minute segment of the population (such as shamans, prophets, and even self-actualizers within Maslow's 1 context), and if the psychedelics act as a catalyst for such experiences, then their widespread availability portends significant social consequences. The most profound long term consequences of the increasingly widespread use of psychedelics may not be medical or even psychological in nature, but rather socio-logical. Altered states of consciousness create nothing less than new perceptual configurations which may well spell the end of social institutions based upon modes of perception which are incongruent with new perceptions being attained by increasing numbers of people via the psychedelic experience.
