Pot Smokers Might Not Turn Into Dopes After All

ananyo writes "Back in August last year, we discussed a study reportedly showing heavy marijuana use in teenagers had been linked to a decline in IQ in later life. Now, a new analysis suggests that the study may have been flawed. Using the same data, the researchers found that they could explain the IQ drop by properly accounting for socioeconomic factors — such as individuals from poorer backgrounds being more likely to smoke cannabis as well as having reduced access to schooling."

      Hence the "war on fat", has actually caused the rise in obesity and diabetes, in addition to the heart disease that it was an attempt to reduce.
