Pot can make you dumber, according to a new study. The findings of the study, which come as little surprise to most, were presented to the Society for Neuroscience.Scientists tracked the cognitive abilities of 33 chronic marijuana smokers and found that regular use of the drug resulted in significant impairment while completing tasks like sorting playing cards.
The study found that the more marijuana the person used, the worse the impairment. Those who began smoking pot before age 16 performed the worst, suggesting that early use of the drug can cause more serious brain damage.
In a recent survey of Americans almost 26 million people admitted to smoking marijuana at least once during the year 2008.
