I recommend this book for any person interested in acquiring basic knowledge in substance abuse and anatomy of the central nervous system (Dr H. C. Wazis of Pharmacology and Toxicology Faculty of Pharmacy University of Maiduguri Nigeria). This literary work has highlighted one of the areas of scientific collaboration between physical sciences and health sciences. The use of electrical electronics in assessing changes in reaction time as a result of substance abuse is quite revealing (Dr Timothy Y. Samuel Head of Pharmacology and Toxicology Faculty of Pharmacy University of Maiduguri Nigeria). The prototype work highlighted in the book is worthy of commendation (Prof Nuhu A. Danjuma President: Neuro-science Society of Nigeria).
