Daily smoking can cause your brain to shrink, a recent study of more than 28,000 people revealed.
Scientists previously discovered that smokers tend to have smaller brains than non-smokers, in terms of volume, but were unsure whether smoking is the cause, or if people with smaller brains are more susceptible to the habit.
The new report, published in medRxiv, provides evidence that daily smoking causally shrinks the brain.
The study was conducted using brain imaging data from a large repository of genetic and health data from UK-based participants and then combined the imaging data with the participants’ self-reported smoking habits, collected in surveys.
Researchers found that compared to people that have never had a daily smoking habit, daily smokers had brain volumes that were 7.1 cubic centimeters smaller, on average.
Each year spent smoking one pack a day was linked to a roughly 0.15 cc decrease in grey matter volume, on average, which the researchers say supports the idea that smoking causes reduction in brain size.
