„With High sein Böckem and Jungaberle managed to write a drug education book which more than deserves its name (…). High sein is the best, most comprehensive and detailed book relating to drugs. It has to be recommended warmly as a set book for young adults and their parents. Every person who works full-time or voluntarily with adolescents should have read it. And with a critical discussion about it the book is more than suited to be teaching material.“
