mechanisms of addiction and schizophrenia

Doctors have historically noticed that Schizophrenics smoked at a much higher
rate than that of the typical population. This correlation is still evident
today. Review the possible mechanisms of addiction and schizophrenia. Visit
the Ashford University Library to locate at least one peer reviewed article that
was published within the last five years which proposes a biological mechanism
for the relationship between Schizophrenia and smoking. 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
initial post should be a minimum of 250 words and utilize at least one
peer-reviewed source published in the last 5 years.
