Fascinating reading a report that prenatal and adolescent exposure to tobacco smoke have been found to be associated with changes in brain pathways to relay ear signals.  Most pronounced with teenage smokers.

Other research reports teenage exposure to smoking resulted in reduced auditory and visual attention with boys being most affected. Quite possible that such teenager’s hear and understand less.

No research yet to establish whether the affects are reversible.

I’d always understand it was bad for your health. But it now appears quite convincing that smoking is bad for your brain development.
