Cannabis use disorder (CUD) affects approximately 9% of cannabis users and carries clinically significant impacts on respiratory, cardiovascular, and mental health that clinicians must recognize and address. Understanding CUD’s diagnostic criteria and health consequences is essential for appropriate patient screening, counseling, and treatment planning in cannabis medicine.
Cannabis use disorder is characterized by clinically significant impairment from continued cannabis use despite negative consequences, with diagnostic criteria including tolerance, withdrawal, and inability to control use. Health impacts span multiple systems: respiratory effects include chronic bronchitis and increased respiratory infections; cardiovascular risks include increased heart rate and potential arrhythmias; mental health consequences encompass increased anxiety, depression, and cognitive impairment, particularly with heavy use initiated in adolescence. Withdrawal symptoms, while not life-threatening, can include irritability, sleep disturbance, decreased appetite, and physical discomfort lasting 1-2 weeks.
“I screen every cannabis patient for signs of problematic use because CUD is real and underdiagnosedโpatients often don’t recognize when therapeutic use has crossed into dependency. The key clinical question isn’t whether cannabis can be problematic, but how to identify and address it early while preserving access for appropriate medical use.”
