A book for Kids??

I friend send me this book link. I read what the site had, and um, I'm still not sure how disturbed to be. In college my husband and I , Art and Music majors respectively, lived in artsy digs, the Music/Art student dorm. It always had that funky smell, mostly the art side, the music people were too OCD to have anything possibly hurt their mouths or throats. We never partook, but if others wanted to waste brain cells, whatever, less competition in auditions and art shows. That said, I still have a issues with a kids book. Take a look, let me know what you think.
