In December 2010, Arizona voters passed the Arizona Medical Marijuana Act (AMMA). The AMMA went into effect on April 14, 2011, making Arizona the 14th state to adopt a medical cannabis law.

Medical cannabis patients in Arizona bought a record 55 tons of cannabis products in 2018, a 41% increase over the 39 tons that were purchased in 2017, according to a report from the state Department of Health Services.

As of December 2018, Arizona had 186,002 registered medical cannabis patients, compared with about 155,500 at the end of 2017, and more than 130 state-licensed dispensaries. Arizona’s medical cannabis program added over 30,500 patients to its rolls over the course of the year – a 20% increase – firmly establishing the state’s medical cannabis market as the third largest in the United States.

  • Medical cannabis sales in Arizona grew to about $400 million in 2018 according to a report.
