The group was established by Tod Mikuriya, MD to help physicians share and exchange data about cannabis use by their patients. In 2004, the CCRMG formed The Society of Cannabis Clinicians (SCC) to facilitate voluntary medical standards for physician-approved cannabis under California law (HSC §11362.5).
The CCRMG published their research findings in the unconventional Journal of Cannabis in Clinical Practice O'Shaughnessy and is in the process of developing an online research archive[permanent dead link]. CCMRG maintains the William B. O'Shaughnessy Archives.
