The Doctor Behind the Difference

Dr. Ben Caplan, MD, is among the most trusted voices in modern cannabinoid medicine. A board-certified family physician and Harvard-trained clinician, he has guided more than 30,000 patients through evidence-based cannabis care,  safely, effectively, and without stigma.

His commitment to education and patient advocacy has earned him something extraordinary: recognition from a sitting world leader for advancing medical cannabis care with integrity and science,  a distinction no other cannabis physician has received.

Dr. Caplan is also the author of The Doctor-Approved Cannabis Handbook, distributed worldwide by Penguin Random House. He continues his mission through CED Clinic, EO Care, and The Commonwealth Project, leading initiatives that expand access to high-quality cannabis care across the U.S.

Why Massachusetts Patients Choose CED Clinic

When you search for a medical cannabis doctor in Massachusetts, you’ll find hundreds of listings. But most are transactional, quick certifications without meaningful guidance.

CED Clinic was built to be different. Here, patients receive personalized, physician-guided cannabis care that considers every detail, from your medical history and medications to your lifestyle, tolerance, and goals. Whether you’re seeking relief from chronic pain, anxiety, sleep problems, or menopause, our approach begins with you, not with a product.

Our telehealth model connects patients statewide, from Boston to Springfield, Worcester to the Cape, to experienced cannabis clinicians in a secure, judgment-free space.

“We don’t just help patients get access,” says Dr. Caplan. “We help them understand how cannabis can truly support balance, healing, and quality of life.”

Understanding the Endocannabinoid System

The endocannabinoid system (ECS) is the body’s natural balancing mechanism, a network of receptors that regulates sleep, mood, inflammation, and pain. When the ECS is out of sync, symptoms like anxiety or chronic discomfort can arise. Medical cannabis works by interacting with this system, helping the body regain equilibrium.

Dr. Caplan often describes the ECS as “the thermostat of the body,” fine-tuning functions that keep everything comfortable inside, even as the world outside shifts. At CED Clinic, we teach patients how to engage this system intelligently, using cannabinoids as precision tools, not blunt instruments.

Conditions We Treat – Beyond the Usual Suspects

Many Massachusetts patients arrive after exhausting conventional options. They’ve tried medications that left them groggy or therapies that never quite fit. Cannabis often feels like a last resort, until they realize it can be a new beginning.

• Chronic pain and inflammation
• Sleep issues and insomnia
• Anxiety and depression
• Menopause symptoms
• PTSD and trauma recovery
• Neurological disorders
• Appetite and nausea regulation
• End-of-life comfort care

Each plan is customized to your personal health profile. Learn more about qualifying conditions here.

What to Expect from Your Visit

1. Book a Consultation → Secure your appointment online.
2. Meet Virtually or In Clinic: Discuss goals, history, and preferences with Dr. Caplan or a CED clinician.
3. Receive Personalized Recommendations: Get tailored guidance on products, dosing, and delivery methods.
4. Ongoing Support: We help you fine-tune your experience and track results.

Many patients say their visit felt “more like being heard than being treated.” We take that as the highest compliment.

Evidence, Not Anecdotes

Unlike much of the industry, CED Clinic builds on data, not trends. Our work is supported by the CED Foundation Research Library, the world’s largest curated database of peer-reviewed cannabis research. Every recommendation is grounded in evidence, from pharmacology to real-world outcomes.

“If the science changes, so should the care.” – Dr. Benjamin Caplan

Compassion Meets Clinical Rigor

What sets CED Clinic apart is its depth of expertise and warmth. Cannabis care should feel safe, human, and empowering. Patients often describe their first visit as “eye-opening,” not because of the cannabis itself, but because someone finally treated them like a whole person again. That’s what real medicine is, and what CED Clinic has delivered to Massachusetts since its founding.

Join the Doctor-Approved Revolution

Dr. Caplan’s leadership extends beyond the clinic. As Chief Medical Officer of EO Care and The Commonwealth Project, he’s shaping national policy and digital infrastructure to bring cannabis care into mainstream healthcare. He teaches, lectures, and collaborates with academic and governmental institutions, advancing understanding of the endocannabinoid system. It’s not just about changing medicine, it’s about changing how medicine thinks.
