Yes.

You likely won't, either. It exists, but isn't something that Barnes and Noble, Waldenbooks, et al carry. Last place I saw one for sale was from Paladin Press, a mail-order specialty place which had that title, and about a hundered more books on various methods of creating mayhem, most of which are of dubious quality...

You can buy it at some gun shows and other "survival related" events.

It is a cartoon-quality "how to" book that would, as Coloradan pointed out, likely get you killed as it would produce a close facsimile to a functional destructive/defensive device. It's been a long time since I looked at a copy, I don't recall seeing anything about Ricin in it. If so, instructions probaly involved stick-figures and a 1,2,3 explanation chart, leaving off the part where you drop dead from exposure.
