Neuromodulation of hematopoiesis: a hypothesis.

abstract：:Relapse to cocaine, heroin, and alcohol is a common occurrence in ex-abusers of these substances. Although there are many potential causes for relapse, we postulate that one cause in some people may be re-exposure in an anesthesia setting to a drug similar to the formerly abused drug. We hypothesize, for example, that...
