Pasadena Marijuana Doctor

From Roger A. Barnes, MD
Pasadena Medical Cannabis (Marijuana) Evaluations


Ihave 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 thousands of medical cannabis patients in Pasadena, California. 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 call my Pasadena office at 626-344-7596.

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.

Cannabis is remarkably safe. Although not harmless, it is surely less toxic than most of the conventional medicines it could replace if it were legally available. Despite its use by millions of people over thousands of years, cannabis has never cause an overdose death.

About A Medical Cannabis Evaluation

When you visit Roger A. Barnes MD & Associates in Pasadena you will ONLY 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 comprehensive medical marijuana 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.

If you are at a medical marijuana office and you do not see a physician, you can bet that it's illegal. Please don't be fooled by dirt cheap, quick evaluation centers, that don't require medical records or for you to actually see the doctor. Be an informed patient, do your research, look up your doctor's medical license number on the California Medical Board website and or ask to see proof from your doctor. The fee for your evaluation covers you for one year of service. What that means is, if you have questions along the way and need to come back in to meet with your doctor, there will be no additional charges. We offer 24/7 phone and internet customer service to verify your doctors written recommendation. We have appointments available Monday thru Saturday, we are closed on Tuesdays, Thursdays and Sundays. We also have early morning appointments available ask us about our 7:00am or 7:30 am appointments.

Oftentimes people are put on opiates, and then their life is one string of opiates after another. Better - cannabis, this is a flower we're talking about it. It's a flower. It's not a dangerous substance like the opiates that I prescribe and others prescribe for patients living with cancer and pain.
