Surprise, surprise: When you summarize the results of 20 years' worth of the most anti-marijuana studies you can find, you get anti-marijuana conclusions. In what is being touted in sensationalistic press accounts as a "definitive study," an Australian is claiming that his investigation into 20 years of marijuana research shows that cannabis is addictive, causes mental health problems and is a gateway to hard drug use.
Professor Wayne Hall, a drug advisor to the World Health Organization and specialist in addiction at the University of Queensland in Australia, said that heavy, daily use of pot can also lead to car crashes and unhealthy babies. He arrived at this conclusion by hand-picking the most anti-marijuana studies from the past 20 years and passing them off as a "definitive new study."
