I've always wanted a copy of the Anarchist Cookbook just for curiosity, but from what I understand the U.S. outlawed it years ago.
AFAIK it was never outlawed. I don't think the US government has tried to do something like that since the unsuccessful attempt to ban Henry Miller's Tropic of Cancer
. They blocked its import in the 30s when it first came out. But a US edition published in the 60s by Grove Press resulted in a Supreme Court decision that effectively made book banning virtually impossible in the USA. The Anarchist Cookbook
officially frowned upon. Enough so that most of the major bookstores declined to carry or order it after a while. But they also voluntarily declined to carry many other books (mostly on sexual subjects) for similar reasons.
I bought my copy in Paperback Booksmith (a major NE chain - now sadly defunct) back in the early 80s - so I guess most people had stopped worrying about it by then. And, as Renegade pointed out, it was a pretty lame book science-wise. You definitely ran the chance of hurting yourself more that somebody else playing with some of the "suggestions" in that book.
It's much more interesting as a historical artifact than a how-to book. I bought my copy because I have a semi-hobby collecting so-called "banned books" when I run across them. (And FWIW, I've discovered most of them aren't very good or interesting reading.)
