WMG / Latawnya, the Naughty Horse, Learns to Say "No" to Drugs

The book is a Stealth Parody written by drug pushers.
The supposed author of this book is in fact a fictional persona created by the true authors. The purpose of the book is to in fact encourage drug use by making opponents of drugs look ridiculous.

The author wrote the book while on drugs.
The horses are supposed to be anthro, but the author got confused.
Well, how else do you explain the drugs?
