Cannabis Use Can Cause Cognitive Impairments, Researchers Say

New research is showing the potential dangers of marijuana on the brain. It comes from a recent study conducted by the University of Montreal. Researchers found the known cognition impairments associated with the drug, such as slowed processing and difficulty focusing, could linger up to weeks. The study also found verbal learning, retention and recall were especially impacted for long periods even after the initial high had worn off.
