Comprehensive account of psychedelic world. Michael Pollan has a explored the psychedelic world in quite an academic way, however at certain places he does seem to be erring in favour of psychedelics.
For example, attributing NASA's earth catalogue project to LSD ( with an open ended maybe). Then making broad generalisations like " closer to two million Americans had tried LSD by 1969, this cadre had indeed blown the mind of America, leaving the country in a substantially different place."
( That's an utterly simplistic view of social change and shows heavy bias ).
Other than that, he has explored and explained the psychedelics world from spiritual, humanistic, psychoanalytic, or neurological angles which is great.
His choice of words in explaining his own psychedelic experiences has been amazing.
This is the first time I have read anything on this topic and the author took me through a fascinating discovery of the history, current neuroscience and his own experience with psychedelics. Highly recommend.
