Your likelihood of getting a prescription for medical marijuana depends on which state you call home, according to a chart released by the Marijuana Business Daily.

MBD columnist Becky Olson points some discrepancies in how the drug is prescribed. While Illinois, for example, has the longest list of qualifying medical conditions, there's less than one medical marijuana patient per 1,000 adults. Compare that with Colorado, which has the second highest density per capita - 26 patients per 1,000 adults - despite a much shorter list of conditions for which adults can be prescribed the drug.

One driving factor behind the difference? Whether docs are allowed to prescribe it to treat pain. States that list pain as a qualifying condition tend to have a much higher patient density.

Doctors can prescribe marijuana for chronic pain in Colorado, but they can't in Illinois.

Other factors include state laws stipulating background checks for would-be patients, black market prices, and surrounding home cultivation. Check out the full chart below, and read Becky Olson's analysis here.
