In 1989 CNS Productions published William Cohen's and Darryl Inaba's textbook
Uppers, Downers, All Arounders (), now in its 8th edition. The book was based on the many interviews with clients from the expanding film catalog, the onset of the
crack epidemic, and the multicultural needs of patients.
Uppers, Downers, All Arounders was Dr. Inaba's and William Cohen's way of explaining the physiological and pharmacological responses that the body has to
psychoactive drugs, those chemicals that can pass through the blood brain barrier and produce a mental effect in the
central nervous system. Thus, uppers stimulate, downers depress, and psychedelic drugs have a variety of effects on the
neurotransmitters. ==Filmography==
