i found this excerpt from the book Carl Sagan : A Life in the Cosmos http://www.williampoundstone.net/Sagan.html "Sagan and Lilly drifted apart. While he admired Lilly as a visionary, Sagan believed that Lilly was veering further and further from science. As to LSD, Sagan felt it was an entirely different matter from marijuana. It was a new and unknown chemical that had not been "tested" by centuries of cultural practice. Sagan reasoned that LSD is hazardous because its dosage is so minute and its effect is delayed. A user cannot tell he has consumed too much until it is too late." maybe he changed his mind later?? i doubt it.
yea i mean its something easy to confuse since Aldous Huxley was clearly a big fan of Blake. haha yea lots of people say Blake was schizo.
Interesting that Sagan would say that. While not being around for centuries, it had been around for over 20 years by then and extensively tested clinically. But it was also during the era when a lot of hype and speculation as to it's safety was rampant and before a lot of serious, non-biased research into it's risks had been done. Who knows, he may have tried it later in life after it's physiological safety had been confirmed by research conducted in the late 60's and early 70's. I personally don't know if Sagan tried LSD, I was just speculating, but it really is no secret he smoked pot.
