This article is an extension of earlier published work describing the neuroblastoma hybrid cell line and examining the effects of morphine and other narcotics upon enzyme activity. The authors find that morphine and other narcotics inhibit enzyme activity and that the inhibition is dependent upon morphine receptors. This leads to a hypothesis concerning the molecular basis for narcotic addiction and tolerance at the end of the article.
