James Howard responds:
I have a theory of schizophrenia, dependent upon reduced brain
development and function, due to reduction of DHEA in schizophrenics.
Smoking  increases DHEA.  I suggest the positive effect of nicotine in
schizophrenics is an increase in DHEA, and is the reason for heavy
smoking in schizophrenia.  (This increase in DHEA may be  the reason
for all nicotine consumption, and, ultimately, may be  the cause of
addiction in nicotine use and other drugs of abuse.)  My explanation
of this is in detail at http://www.naples.net/~nfn03605 on the web.
