Yes, weed is legal in Arizona for adults aged 21 and older. Adults may purchase recreational marijuana from licensed dispensaries, possess limited amounts and grow a restricted number of plants at their primary residence.
However, legalisation does not mean marijuana can be used anywhere or carried in unlimited quantities. Public smoking, impaired driving, unlicensed sales and possession on certain federal properties can still lead to legal trouble.
When Did Arizona Legalise Recreational Weed?
Arizona voters approved Proposition 207, also called the Smart and Safe Arizona Act, in November 2020. The law legalised recreational marijuana for adults aged 21 and older.
Licensed recreational sales began in January 2021. Arizona also continues to operate its separate medical-marijuana programme for registered patients.
Adults do not need a medical-marijuana card to buy recreational products. They must show valid government-issued identification proving that they are at least 21.
How Much Marijuana Can an Adult Possess?
An adult aged 21 or older may legally possess, purchase or transport up to one ounce of marijuana. No more than five grams of that amount may be marijuana concentrate.
Concentrates include products such as wax, shatter and certain concentrated cannabis oils. Edibles, vape products and other marijuana products are also regulated.
Possessing more than one ounce but no more than two and a half ounces is a petty offence, provided the marijuana is not intended for sale. The permitted concentrate amount within this higher limit is no more than 12.5 grams.
Possessing substantially larger quantities or possessing marijuana for sale without the proper licence can result in serious criminal charges.
Can You Grow Marijuana at Home?
Arizona allows adults to grow marijuana at their primary residence. Each adult aged 21 or older may cultivate up to six plants for personal use.
A household with two or more adults may grow no more than 12 plants in total. The limit does not increase when three or more adults live at the same address.
The plants must be grown inside an enclosed area, such as a locked room, closet or greenhouse. The growing area must prevent access by minors. The plants must also not be visible to the public without the use of binoculars, aircraft or other visual equipment.
Growing plants openly in a front garden or an unlocked area can result in penalties, even when the number of plants is within the legal limit. Landlords may also restrict cultivation or smoking through lease conditions.
Is It Legal to Smoke Weed in Public?
No. Smoking marijuana in a public place or open space is a petty offence in Arizona.
Public places can include streets, pavements, parks, restaurants, shopping areas and other locations open to the general public. Smoking may also be prohibited in hotels, apartment common areas, workplaces and private businesses.
Marijuana is generally intended to be consumed on private property where the property owner permits it. A business owner, landlord or homeowner may prohibit marijuana use on their premises.
Licensed dispensaries do not automatically operate as public consumption lounges. Purchasing marijuana from a dispensary does not mean it can be smoked immediately outside the shop.
Can You Give Marijuana to Another Adult?
An adult may give up to one ounce of marijuana to another adult aged 21 or older. No more than five grams may be concentrate.
The transfer must be free. The giver cannot receive money, goods, services or anything else of value in exchange. The transfer also cannot be advertised or promoted publicly.
Calling a marijuana sale a “gift” does not necessarily make it legal. For example, selling an overpriced ordinary item and including marijuana supposedly for free may still be treated as an unlawful sale.
Only properly licensed marijuana establishments may legally sell recreational marijuana.
Is Driving After Using Weed Legal?
No. Arizona prohibits driving or being in actual physical control of a vehicle while impaired by marijuana.
A person can be charged when marijuana affects their ability to drive to even the slightest degree. Recreational legalisation is not a defence to impaired-driving allegations.
Arizona law does not establish a simple THC limit equivalent to the 0.08 alcohol limit. Police and prosecutors may instead rely on driving behaviour, field observations, blood-test evidence and other facts.
Marijuana should remain in a closed package while being transported. It should not be used by the driver or passengers inside a moving vehicle.
Can Employers Still Test for Marijuana?
Yes. Recreational legalisation does not require an employer to permit marijuana use, possession or impairment at work.
Employers may maintain drug-free workplace policies and may conduct drug testing when permitted by law. Medical-marijuana patients have some additional protections, but those protections do not allow them to use marijuana at work or work while impaired.
Employees should therefore review their employer’s policy rather than assuming that legal off-duty use cannot affect their employment.
Does Federal Law Still Matter?
Yes. Arizona law cannot remove federal restrictions. Recreational marijuana is not generally legal under federal law, and possession may be prohibited on federal property.
This is especially important in Arizona because the state contains national parks, monuments, forests, military installations and other federally controlled areas. State permission does not automatically protect someone carrying marijuana in these locations.
Taking marijuana across state or international borders is also risky, even when travelling to another state where marijuana is legal.
The Legal Position
Weed is legal in Arizona for adults aged 21 and older, but only within specific limits. Adults may possess up to one ounce, purchase from licensed dispensaries and grow up to six plants each, with a maximum of 12 plants per household.
Public smoking, impaired driving, unlicensed sales, underage possession and violations involving federal property remain unlawful. Legal use therefore depends not only on a person’s age, but also on the amount, location and manner in which the marijuana is possessed or consumed.
