"On a foundation of sophisticated techniques based on current understanding of brain chemistry and function, and using tight, thorough reasoning, the author concludes that duration, not frequency, of use produces identifiable impairment in the performance of complex cognitive processes, and that at least some of the impairment remains after abstinence....the text is sufficiently clear that most nontechnical readers will follow the arguments. This will be an especially valuable book for cannabis researchers, while those in clinical and policy making positions will find the conclusions enhanced by the rigor with which they are achieved." Yonah Klem, Readings
