HEAVY marijuana use over many years appears to shrink parts of the brain that control emotion and memory, an Australian study shows.
Brain scans on 15 men who smoked at least five joints a day for more than a decade show for the first time that they have structural brain abnormalities not seen in non-smokers.
The hippo campus, thought to regulate emotion and memory, was 12 per cent smaller in volume and the amygdala, involved with fear and aggression, was reduced by seven per cent.
This explains why i see sometimes the most weirdest posts here... People, stay of the drugs...
