In loving memory of Roger A. Barnes, MD

I have been a licensed physician since 1976. I served as an anesthesiologist in the United States Navy, my last tour of duty was on the teaching staff at National Naval Medical Center, San Diego. In 2005, I retired from a busy private anesthesia and pain management practice. My traditional medical training and experience did not include alternative treatment modalities such as medical marijuana.

For the last 5 years I have provided medical marijuana evaluations to patients in Pasadena. I have learned that medical marijuana is not only an effective treatment for a wide variety of conditions but also the safest medicine that I have ever recommended. Many of my patients are seniors who have never used marijuana/ Cannabis or not since their youth. Most of my patients have found relief from their symptoms, frequently using smoke-less marijuana.

I am committed to the California Medical Marijuana Program and to the legal protection it provides to qualified individuals. If you are interested in determining if you qualify as a medical marijuana patient under the California Medical Marijuana program please contact our office.

According to Prop 215 (also known as the Compassionate Use Act of 1996), seriously ill Californians have the right to obtain and use Marijuana aka Cannabis for medical purposes where the medical use is deemed appropriate and has been recommended by a physician who has determined that the person's health would benefit from the use of marijuana in the treatment of cancer, anorexia, AIDS, chronic pain, spasticity, glaucoma, arthritis, migraine, or any other illness for which marijuana provides relief.

About A Medical Cannabis Evaluation

When you visit Roger A. Barnes, MD you will be evaluated by a California licensed medical doctor. The California medical board says that ONLY A PHYSICIAN IS AUTHORIZED TO RECOMMEND medical use of marijuana. Patients should be aware that in order to be a valid California medical marijuana patient, the evaluation needs to be done by a California licensed Medical Doctor (MD) or Doctor of Osteopathy (DO) only. So this means that, medical assistants, chiropractors, Physician Assistants (PA's), or anyone else who is not a California licensed MD or DO cannot legally evaluate patients for medical marijuana. The physician needs to complete a medical examination and record an assessment of the patients medical condition. Dr. Barnes has been providing patients with evaluations for over 5 years. He is compassionate and enjoys working with patients to determine what works best for them and how to safely consume their medicine.
