Clinical Commentary

Dr. Caplan’s Take
# Clinical Reflection These 20 items collectively signal that cannabis medicine is maturing into a field requiring sophisticated risk-stratification and population-specific guidance: we now have credible evidence for efficacy in circumscribed conditions like chronic pain and select seizure disorders, yet simultaneously robust data on iatrogenic harms in vulnerable populations, particularly adolescents and pregnant women. The research underscores that cannabinoid therapeutics cannot be practiced as a monolithic intervention; dosing, formulation (flower versus edibles), cannabinoid ratio, and patient psychosocial context fundamentally determine safety and efficacy outcomes. My practice must therefore shift from cautious skepticism or naive enthusiasm toward methodical, evidence-based patient selection and informed consent conversations that openly address both the genuine therapeutic promise and the real developmental and psychiatric risks documented in these studies.
