There's a very simple thing that needs to be recognized: drugs are just that, drugs. They interact with our physiology. They affect our brain in a variety of ways. And we need to be informed of those ways properly before "experimenting" with any. They don't unlock any mystical understanding of the world, because everything that happens while on drugs is still subjective experience.

I'm all for people taking whichever drug they wish to take, but they need to stop peddling bullshit pseudoscience. Thank you for writing this. (And the Hitch quote was well-chosen)

I believe Sam Harris is someone with valuable insight into this. He is very open to them and ways in which a variety of drugs can affect or enhance our cognition, without falling into pseudoscience and mysticism.
