The research by the Royal Children's Hospital tracked a group of 2,000 youths for seven years between the ages of 14 and 21, a report in today's The Age newspaper said. The director of the hospital's Centre for Adolescent Health, George Patton, said the results of the research were very striking. "The effects are profound, particularly in young women, where the rates of mental health problems have increased many, many times in daily cannabis users," he told The Age. However, details are being withheld until the full study was published in an international medical journal next month. Professor Patton said the study was the best evidence yet that cannabis was a health risk and led to mental illness and depression. It has not so far been proven that cannabis use causes depression. Rather, it was thought that depressed people might have turned to it for relief or that some personality types could be prone to both cannabis dependence and depression. "There's been a bit of a question in people's minds as to what was the chicken and the egg here," Prof Patton said. "What we've been trying to do is disentangle some of that in our work." He said occasional or experimental use probably had no effect on mental health at all. - --- MAP posted-by: manny lovitto
