Home Cultivation and Processing
Recreational users can grow up to 6 plants per person, but only in a locked, enclosed area not visible to the public. If you grow more than 1 ounce from your plants, you must keep the excess at home and not transport it. Medical patients can grow up to 12 plants under certain conditions.
Where You Can Consume Cannabis
Consuming cannabis in public is a petty offense in Arizona. Public places include parks, sidewalks, roads, and any place open to the public. You can consume on private property, but landlords and property owners can set their own rules. Some cities have additional restrictions on smoking in multi-unit housing.
Driving and Employment
Driving under the influence of cannabis is illegal. Arizona law prohibits driving with THC metabolites in the blood, which can lead to DUI charges even if you are not impaired. Employers may still drug test and enforce zero-tolerance policies. Arizona law does not protect employees who use cannabis off-duty from termination in most cases.
Penalties for Violations
Possessing more than the legal limit can result in fines or jail time. For example, possessing 2 to 2.5 ounces of flower is a petty offense with a fine. Larger amounts can be misdemeanors or felonies. Selling cannabis without a license is a felony. Driving under the influence carries mandatory penalties including license suspension.
