about CED Clinic

CED Clinic was founded in 2017 by Benjamin Caplan, MD in order to provide medical services and oversight to individuals seeking cannabis treatment. With an ever-increasing amount of research linking cannabis to positive treatment outcomes, the clinic strongly supports a holistic approach to healthcare and wellness that includes medicinal cannabis.

The clinic offers comprehensive treatment oversight and has seen medicinal cannabis help patients overcome a wide variety of diseases. Among other ailments, CED Clinic patients have overcome emotionally devastating PTSD, quality-of-life destroying Lupus, the paralyzing effects of severe epilepsy, and debilitating chronic pain issues that had previously only been treatable using high addictive substances.

The clinic’s mission is to provide a comfortable and professional environment where patients and physicians can openly discuss medicinal cannabis and its benefits.
