I find Terence McKenna's writing style extremely heavy-handed. Just as no one religion is good for everyone, so too, no one drug is "good" for everyone. The idea that taking hallucinogens is going to "lead us back to Eden" is simplistic and fundamentalist. It may for some, yes, but not for all. I agree that these kinds of drugs should be legal and used in a sacred, ritualized way, but they are not good for all people. He also has really interesting (but again, very heavy-handed) theories about other drugs, like the French Revolution being traced back to the culture's embracing of coffee and cafes. This book is a mixed bag of overbearing proclamations about all kinds of "drugs" mixed with some very interesting theories.
