At a moment when cannabis has become woven into the daily lives of millions, science has yet to agree on what it does to the mind. Researchers publishing in the same era are arriving at opposite conclusions — some finding measurable changes in memory and cognition, others finding no significant effect at all. This is not a minor dispute over degree; it is a disagreement about whether harm exists in the first place. The uncertainty leaves users, physicians, and policymakers navigating a question that modern research, despite its ambitions, has not yet answered.
