Arizona

Overview

Arizona voters approved adult-use cannabis through Proposition 207 (the Smart and Safe Arizona Act) in 2020, on top of the medical program the state has run since 2010. Adults 21+ may possess up to one ounce of cannabis, of which no more than five grams may be concentrate, and may grow a limited number of plants in an enclosed, locked area out of public view. The Arizona Department of Health Services licenses dispensaries and keeps running the medical program, which has its own possession allowance for cardholders.

Driving and Cannabis

Driving while impaired by cannabis is illegal in Arizona, as it is in every state, whether or not the cannabis was obtained legally. Officers may rely on field sobriety tests, drug recognition evaluations, and blood tests, and some states set specific THC limits or zero-tolerance rules. Consuming cannabis in a vehicle and carrying open or unsealed packages where the driver can reach them are commonly prohibited. If you have used cannabis, the safest choice is not to drive.

Crossing State Lines and Federal Law

Taking marijuana across state lines is illegal under federal law, even between two states where cannabis is legal, and it may also violate the law of the state you enter. Marijuana is also prohibited on federal land, in national parks, and at airports under TSA jurisdiction. In 2026 the federal government moved FDA-approved products and state-licensed medical marijuana to Schedule III, but adult-use marijuana remains a Schedule I substance, and rescheduling does not legalize interstate transport. Separate federal changes to the legal definition of hemp take effect in late 2026 and will restrict many intoxicating hemp-derived THC products.
