Neuroscientists at The University of  Montreal studied over 3800 teens entering high school and followed them during the subsequent 4 years tabulating their cannabis and alcohol use while assessing their cognitive functions.  They documented deficits in memory recall, reasoning, and self-control in weed-using students that did not appear in students preferentially using alcohol recreationally. Urban legend has it that marijuana is safer than alcohol.  Studies such as this indicate that the jury remains out on this issue.   Canadian Association for Neuroscience.
