Here's some new NYT video:
And here's a recent episode of Stuff You Should Know: "How LSD Works."
Notably, both of these things go back to the phase in the development of LSD when psychologists were finding medical applications for the drug, and both bemoan the transition out of the medical setting to the spiritual/recreational use associated with Timothy Leary and the hippie movement. Both seem hopeful about reviving the medical use and have nothing good to say about the freedom of individuals to use the drug for our own autonomous purposes. Everything is so medicinal these days. I would think that the spiritual (and intellectual) pursuit would be placed on a highest level, but Timothy Leary really scared the bejeezus out of the authorities half a century ago. Those 2 words, drop out. There was a tremendous fear that people would shed the old work ethic, and that was a freakout from which America has never come down.
