7 things to know about Arizona's medical marijuana program

Arizona's medical marijuana program was created by the 2010 Arizona Medical Marijuana Act and is run by the Arizona Department of Health Services. A licensed MD, DO, naturopathic or homeopathic physician reviews the patient's records, examines them and signs the state certification form. The patient then applies online through the ADHS licensing portal with a photo, ID and fee. Cards last two years. Adult-use cannabis became legal in 2020, but the medical card still offers higher possession limits, access for patients under 21, and lower taxes on purchases.
