WHY IT MATTERS: Patients using medical cannabis should know that a formal diagnosis or physician recommendation does not eliminate the risk of developing Cannabis Use Disorder, and open communication with your prescribing doctor about frequency and dosage is essential for long-term safety. CLINICAL OVERVIEW: Cannabis Use Disorder is a clinically recognized condition characterized by continued use despite negative consequences, with estimated prevalence rates ranging from roughly 9% of all users to as high as 33% among daily users. The medicalization of cannabis has created a complex dynamic where legitimate therapeutic access may, in some patients, lower the perceived risk of the substance and contribute to problematic use patterns.
