A recent report in New Scientist showed that smoking cannabis has been linked to having a small brain at least if the dope is taken in large doses, over a long period. Researchers at the University of Melbourne, Austrailia scanned the brains of 15 heavy users, who had smoked at least 5 joints daily for more than 10 years. The volume of their hippocampus, involved in memory and regulating emotion, was on average 12% smaller than non-users, while the amygdale, involved in feeling fear and aggression, was 7.1% smaller. The cannabis users also scored worse on memory tests and were more likely to suffer from social withdrawal or paranoia. Terry Pfau DO, HMD
