Can smoking shrink brain?

Scientists from the Montreal Neurological Institute at McGill University and the University of Edinburgh report new evidence that long-term smoking could cause thinning of the brain's cortex. This outer layer of the brain is where critical cognitive functions such as memory, language, and perception take place.
