Does Medicaid or medicare pay for medical marijuana?

I live in Glenwood Springs, Colorado. I was informed by my primary care physician that she was unable to sign the required Doctor Forms necessary to complete the Medical Marijuana Certification process. Further more, even their cancer patients were given the either/or option of Prescription Drugs or Medical Marijuana. This restriction imposed on all Physicians or Clinics receiving Federal Funding. The answer is clearly know No.
