The book
The Doctor-Approved Cannabis Handbook
Reverse Disease, Treat Pain, and Enhance Your Wellness with Medical Marijuana and CBD. By Benjamin Caplan, MD.

Why this book
Specific guidance, from a doctor who practices cannabis medicine
For years, most doctors either warned patients away from cannabis or said nothing at all. Patients were left to figure it out alone, from dispensary staff, friends and the internet.
Dr. Caplan wrote the Handbook to close that gap. It is the guidance he gives patients in his own practice: what cannabis is, how it works in the body, how to choose a product and a dose, and how to build a plan for a specific condition, alongside the rest of your care. It is written to be read by patients and caregivers, and to be useful to the clinicians who support them.
