No monster vibration, no snake universe hallucinations. Many tiny jeweled violet flowers along the path of a living brook that looked like Blake's illustration for a canal in grassy Eden: huge Pacific watery shore, Orlovsky dancing naked like Shiva long-haired before giant green waves, titanic cliffs that Wordsworth mentioned in his own Sublime, great yellow sun veiled with mist hanging over the planet's oceanic horizon. No harm.
A drug is neither moral nor immoral -- it's a chemical compound. The compound itself is not a menace to society until a human being treats it as if consumption bestowed a temporary license to act like an asshole.
No drug, not even alcohol, causes the fundamental ills of society. If we're looking for the sources of our troubles, we shouldn't test people for drugs, we should test them for stupidity, ignorance, greed and love of power.
