The New Zealand researchers found that teens who smoked pot heavily (at least four days a week) lost an average of eight IQ points between the ages of 13 and 38. Adults who had smoked as teens tended to show more pronounced deficits in memory, concentration, and overall brainpower in relation to their peers.
