In October, 2012, researchers released a study linking cannabis use in teens and lowered IQ. A second study, released today, provides a different interpretation of the data. The IQ changes in the different populations could be due to their socioeconomic status, not their pot use. The study used data from the Dundin cohort, a group of more than 1,000 children born between April 1, 1972 and March 31, 1973 in Dundin, New Zealand. They are now 38, and still being studied. All in all, it sounds like the link between teen pot use and IQ is still very questionable, so don't take the word of just one researcher. - Business Insider
