I'm not a neuroscientist, just an interested person.. I seem to recall
seeing the following in a book entitled 'aids to pharmacology'. it
stated that (after quite a long chapter on increased risks associated
with smoking) one of the decreased risks was susceptibility to
parkinson's disease.

Whether this is due to increased mortality of smokers or the effect of
nicotine on the brain, it didn't say.
