Here's Your Guide to Proposition 205, Arizona's Marijuana-Legalization Ballot Measure

Arizona voters will either make history on Tuesday, November 8, by legalizing marijuana for adults 21 older, or perpetuate the arrest and jailing of cannabis consumers.

Whatever happens, Proposition 205 will be among the most-watched races in the state on Election Day. Both the campaign and its opponents have spent millions of dollars trying to convince voters. Arizona's not facing the question in isolation: The ballot measure represents a national marijuana-freedom revolution, as residents of four other states — California, Maine, Massachusetts, and Nevada — will also decide whether to approve adult-use measures.

If voters in all five states approve the measures, they'd join Colorado, Washington, Oregon, Alaska, and Washington, D.C., in redefining marijuana use and culture in the United States. In addition, medical-marijuana measures will appear on Tuesday's ballots in Arkansas, Florida, Montana, and North Dakota.
