I was so struck by this passage from Alexander Shulgin’s book Tihkal (Tryptamines I Have Known and Loved) that I had to share it here:



Professor David Nutt has made a similar comparison, describing the UN’s ban on psychedelics as “the worst case of scientific censorship since the Catholic Church banned the works of Galileo.”

You can read the second half of Tihkal (the chemical section) on Erowid, or better yet on isomerdesign.com where it is more accurate and more user-friendly. But the first half of the book remains copyrighted, so if you’d like to read the whole thing, buy a copy! It’s one of the classics of psychedelic literature. Sasha and Ann Shulgin have done more to advance the chemical understanding of tryptamines and phenethylamines than anyone else in history. They are heroes to millions of psychonauts thanks to their many years of courageous self-experimentation and their dedication to sharing the truth, no matter what the cost.

Also, Sasha has suffered ill health in recent years, and cannot afford the medical care he needs. If you feel that you’ve benefited from his life’s work, please consider donating towards his medical costs.
