Bad news for anyone who smoked pot as a teenager...

This is your brain. This is your brain on pot...  

A new study out of Duke University states: The use of cannabis in adolescence, while the brain is undergoing critical development, may have neurotoxic effects. In other words, if you smoked pot as a teenager, you may have permanently lowered your IQ. Nice going genius.

So how much of a hit did your intelligence take? Pot smoker’s IQs dropped an average 8 points. Those who quit smoking pot still had lower IQs than they did at the start of the study.
