No data available for: North Dakota, Ohio, West Virginia.
* Arkansas has started issuing medical marijuana registry ID cards, but marijuana is not yet available in the state.
** California had 5,848 registered patients in Fiscal Year 2017/2018, but registration is voluntary and most patients are not registered. We made an estimate using the per capita number of patients in Arizona because of geographical proximity. The Marijuana Policy Project's (MPP) Feb. 2018 estimate for California, 1,256,550, used Maine's per capita number of patients.
*** In presenting the number of medical marijuana registration cards printed, Maine's medical marijuana program website states, "This number is not an accurate reflection of the number of patients as it contains all certifications printed, including misprints, reissue of lost certifications and other anomalies."
**** Washington listed 32,123 recognition cards created as of May 16, 2018, but registration isn't required to be a medical marijuana patient except for patients under 18. As a result, we created an estimate based on the per capita patient numbers in Oregon.
