Insane children's book depicts horse smoking drugs, drinking

Ben says:

Picture 7-11

A scan of possibly the most disturbing/hilarious "children's" book ever written [Latawnya, the Naughty horse, Learns to Say "No" to Drugs]. Touches on issues of peer pressure, just saying no, and has pictures of horses doing drugs, drinking, and ODing. Would possibly fit with 50's era appropriateness, but it was published in 1991, ISBN 0-533-09102-0. In-freaking-credible.
