Everyone knows how cigarettes are harmful for your lungs and how it causes lung and mouth cancer but only few know that how smoking effects your brain.

Scientists from Edinburgh University and McGill University have revealed that smoking makes the brain cortex layer thinner. It is the outer layer of brain with functions including memory, language and perception.
The study was based on 500 people who were current or past smokers. They gathered their health data and examined their MRI results, which were then studied with image models and statistical models.
It was observed that when they quit smoking their cortex layer started to become thick, though it was a slow process. Even after 25 years of quitting smoking the cortex layer will be thinner than the layer of a non-smoker.
The study was published in journal Molecular Psychiatry.
