A newly launched campaign to allow for the recreational use of marijuana in Arizona in 2016 is just the latest in what will likely be a slew of state-level legalization efforts for the next election cycle.

A local chapter of the Marijuana Policy Project, the advocacy group that helped legalize marijuana in Colorado, has formed a committee to push the same in Arizona, the Arizona Republic reports. But the Grand Canyon State is just one of a dozen states where the group plans to focus its efforts in the coming years.

MPP has set its sights on passing legalization in about a dozen states by 2017. It plans to focus on legalizing marijuana legislatively in Delaware, Hawaii, Maryland, New Hampshire, Rhode Island, and Vermont in the coming years, while the group hopes to use the initiative process to achieve the same goal in California, Maine, Massachusetts and Nevada.

Recreational marijuana use legalization is already on the ballot this November in Alaska, Oregon and D.C., following successful efforts in Washington state and Colorado. An early-August Public Policy Polling survey found that 49 percent of Alaska voters oppose the measure while 44 percent support it. Support in Oregon was pegged at 51 percent in a June poll by Survey USA.

Arizona already has more than 52,000 active qualified medical marijuana patients using the plant to treat a variety of conditions such as cancer, glaucoma and HIV. Slightly more than 70 percent, however, use it simply to treat chronic pain, according to a July report. The more than 52,000 patients amount to roughly 0.8 percent of the state population.

The Marijuana Policy Project of Arizona isn’t the only group pursuing full legalization in the state. Safer Arizona, which abandoned a push this past June after failing to collect enough petition signatures, has shifted its sights to 2016, announcing on its Web site last week that the group is “just a few months from launching our campaign.”
