What's the Best Book on the World History of Marijuana?

[I Want Buds]

All over the place, I find books about the history of Bud in the US. Some of them pretty good. But I have all those. What I really want is, for someone who may have a great book on the History of Marijuana since the beginning of it's use, to tell me where I can buy it. I can't seem to find anything about that, and if I was to find something, I'd be nervous buying the book in fear that it might be a bunch of crap.
Has anyone come across a really good book about the World History of Marijuana and it's origins?

Never seen any books about this for sale at a bookstore?

I'm reading "Cannabis; A History" by Martin Booth.

Very scholarly, if that's your bag...
