Clinical Commentary

Dr. Caplan’s Take
# Clinical Reflection These studies collectively signal that cannabis medicine is moving toward evidence-based specificity rather than broad therapeutic claims, particularly distinguishing between cannabinoid types (THC versus CBD), product formats (flower versus edibles), and clinical indications where signal exists (chronic pain, fibromyalgia, specific seizure disorders) versus those requiring caution (adolescent use, pregnancy, comorbid psychiatric conditions). The consistent focus on safety monitoring, longitudinal outcomes, and vulnerable populations reflects a maturing field that recognizes cannabis as a pharmacologically active intervention requiring the same rigorous patient stratification and risk-benefit analysis we apply to other medications. My prescribing practice should therefore prioritize conditions with randomized evidence, acknowledge the real psychiatric and developmental risks particularly in younger patients, and resist the temptation to treat cannabis as a broad-spectrum remedy despite its
