The Association of Cannabinoid Specialists is comprised of a diverse group of physicians and other clinicians who specialize in cannabis medicine.

We provide ongoing, detailed care for patients with severe illness.

We use evidence-based medicine and best practices to ensure our patients get the best they can from their treatment. We publish to extend both the art and science of cannabis medicine.


Physicians and other clinicians need a voice in the discussion around laws and regulations of medical cannabis. The ACS is your voice:
