Sure enough, it's a kid's book about grass. But the book is actually a lot more thoughtful than the provocative premise might seem to be at first glance.Link
"It's Just a Plant" is a children's book that takes a similar approach to sex education in talking about another difficult topic. That is, the book explains that marijuana can be a positive and healthy thing for adults, but it's not for children. In twenty years I haven't seen anything quite like this in how it approaches the topic.
