After reading Chapter 11 and 12 in your course text and the article “Considering the Definition of Addiction (Links to an external site.)Links to an external site.”  which covers the biological basis of emotion, addiction (substance  abuse disorder), and disordered behavior, analyze the high rate of  smoking in those diagnosed with schizophrenia compared to the general  population.  Why are smoking cessation interventions less successful in  these individuals? Review the accepted mechanisms of tobacco abuse and  dependence and the etiologic theories of schizophrenia. What are the  biological and/or psychological mechanisms between schizophrenia and  smoking?  Include information on brain structures, pathways,  neurotransmitters/receptors, and psychological factors when discussing  the topic areas above.  Additional emphasis should be placed on relating  the underlying pathology of schizophrenia to tobacco dependence/abuse  and the biological or psychological mechanism of the observed  association of smoking behavior to the diagnosis of schizophrenia.    

 In keeping with the focus of this class, the emphasis should be placed  on the role of neurotransmitter and receptor systems, neuroanatomical  structures, and neurological functional pathways.  You must use a  minimum of one peer-reviewed source that was published within the last  five years, documented in APA style, as outlined in the Ashford Writing  Center. How does the data support the proposed mechanism in the article  you chose?  What other possible mechanisms might explain this  relationship?  Is it possible that biology has nothing to do with the  relationship between smoking and schizophrenia?  Your post should be a  minimum of 250 words.  You may cite and reference your textbook,  required reading and/or multimedia, but these will not fulfill the  source requirement.
