Does Smoking Pot Effect Your IQ?

Does smoking pot affect your IQ? Yes, if you start smoking under the age of 18. A study from New Zealand's University of Otago of 1,000 people IQ tested and followed from 18 to 34 showed that people who smoked and became dependent by 18 had an average drop of 8 points.  Unfortunately, quitting didn't remove the problem researchers reported.  (Modesto Bee, Tue. 28, 2012)
