But smoking has been correlated with reduced cognitive performance as one ages. Likely the vascular effects: reduced blood flow to brain.

> A recent New York study showed that smokers had on average 40% less of the enzyme, monoamine oxidase type-B, in their brains than non-smokers. Levels returned to normal on their giving up smoking. Not merely is the extra dopamine in the synapses rewarding. The level of MAO-b inhibition smokers enjoy apparently contributes to their reduced incidence of Parkinson's and Alzheimer's disease.
