Marijuana laws in Utah
Utah voters approved Proposition 2 on November 6, 2018. The legislature then enacted the Utah Medical Cannabis Act, now in Title 26B, Chapter 4, Part 2. Recreational marijuana is not legal. Patients buy from licensed medical cannabis pharmacies, including some pharmacies authorized to deliver, overseen with the Department of Agriculture and Food and the Center for Medical Cannabis.
A patient’s medical provider sets a monthly limit in the Electronic Verification System. The highest limit is 113 grams of unprocessed flower and 20 grams of THC in all other products, such as tinctures, vapes or gummies. Patients must use only cannabis bought from a Utah medical cannabis pharmacy. Smoking cannabis is not allowed; vaporizing is. Public use is not allowed unless there is a medical emergency. Sharing, selling or giving away medical cannabis is illegal.
Home growing is not part of the program. Bringing cannabis into Utah from another state is illegal even with a Utah card. Non-Utah residents may apply for a separate nonresident card under state rules.
Under Utah Code §58-37-3.9, a person is not guilty of a controlled-substance violation for cannabis conduct that follows the medical cannabis statutes. Marijuana remains illegal under federal law, apart from state-licensed medical marijuana, which moved to Schedule III in April 2026.

How old do you have to be to use marijuana in Utah?
There's no legal age to buy recreational weed in Utah, because recreational marijuana is illegal at any age. Medical cannabis is different. You need a medical cannabis card through the Electronic Verification System after a qualifying provider recommendation. Minors use a minor patient and guardian card. Adults who need help can have a caregiver card. There is also a separate application for a non-Utah resident card.
How much marijuana can you have in Utah?
If you have a Utah medical cannabis card, you can have up to the monthly limit your provider sets in the Electronic Verification System. The highest limit is 113 grams of unprocessed flower and 20 grams of THC in other products, such as tinctures, vapes or gummies. That is the amount you may have from Utah pharmacies, at home or on you, and the cannabis must stay in proper packaging in public. Without a card, possessing marijuana is illegal.
Where can you buy marijuana in Utah?
You can buy medical cannabis in Utah only at a licensed medical cannabis pharmacy, or through a pharmacy that is authorized to deliver. Recreational stores do not exist. You must be registered in the Electronic Verification System. It is illegal to buy cannabis in another state and bring it into Utah, even if you have a Utah card.
Can you grow marijuana at home in Utah?
No, you can't grow weed at home in Utah, even as a medical cannabis cardholder. The state uses a pharmacy model, not patient cultivation. Cannabis production is limited to licensed cannabis production establishments, and patients buy finished products only from licensed medical cannabis pharmacies.
Where can you use marijuana in Utah?
You can use medical cannabis in Utah if you have a card, but you can't smoke it. Vaporizing is allowed. You also can't use medical cannabis in public, indoors or outdoors, unless it is a medical emergency. Recreational use is illegal. Driving under the influence of cannabis is a separate crime under Utah's traffic code.
How do you get a medical marijuana card in Utah?
To get a medical marijuana card in Utah, you need a qualifying condition and a recommendation from a medical provider who participates in the program. Create a UtahID, register in the Electronic Verification System, and apply for a patient card (or a minor/guardian or caregiver card). Qualifying conditions include cancer, epilepsy, PTSD that you are also treating with a mental health provider, persistent pain lasting longer than two weeks, HIV or AIDS, MS, autism, Alzheimer's disease, and others listed by the state. A provider can also petition the Compassionate Use Board.
Can visitors buy or use marijuana in Utah?
Out-of-state visitors can't buy recreational weed in Utah. The state does offer a non-Utah resident medical cannabis card application for people who qualify under that process. Even then, you must buy from a Utah medical cannabis pharmacy; you can't legally bring cannabis in from another state. Without a Utah-recognized card, possessing marijuana in Utah is illegal.
What are the rules on driving and marijuana in Utah?
No, you can't drive high in Utah. It is illegal to drive under the influence of cannabis or another drug, including medical cannabis bought legally at a pharmacy. A medical card is not a defense to impaired driving. Utah Code §41-6a-517 addresses driving with certain controlled substances in the body.
Can an employer in Utah fire you for using marijuana?
Yes, you can get fired for smoking weed in Utah. Recreational use is illegal and has no protection. The medical cannabis statutes do not generally require employers to allow cannabis use or to ignore a drug test, especially for safety-sensitive jobs and federally required testing.
What are the penalties for breaking marijuana laws in Utah?
Without a card, possessing, producing or selling cannabis can be charged under Utah's controlled-substance laws. Cardholders acting within Title 26B, Chapter 4, Part 2, and buying only from Utah pharmacies are protected from those charges under §58-37-3.9. Smoking cannabis, using it in public, sharing it, or bringing it in from another state can still bring penalties.
Are CBD, hemp and delta-8 products legal in Utah?
Hemp and hemp-derived CBD that meet Utah's hemp definition are regulated separately from medical cannabis. Products with 0.3% or more total THC or a THC analog on a dry weight basis are treated as cannabis products under the medical cannabis definitions. Delta-8 and THCA items can fall on either side of that line depending on their composition. Medical cannabis itself must come from a Utah pharmacy. Separately, a stricter federal hemp definition, with a total-THC standard that counts THCA and a 0.4 mg-per-container cap, takes effect December 11, 2026.
Does federal law still apply in Utah?
Yes. Federal law still applies in Utah. Marijuana remains a Schedule I controlled substance under federal law, with one exception: since April 28, 2026, marijuana covered by a state medical marijuana license and FDA-approved marijuana products are in Schedule III. A broader federal rescheduling proceeding was stayed on September 29, 2026, and has no decision date. State law does not change federal rules on federal land, on carrying marijuana across state lines, or on federally required drug testing, such as for DOT-regulated jobs.
Has the law in Utah changed recently, or is it about to?
Utah still has a medical-only program. Recreational marijuana is not legal, and no legalization date is set. Patient purchase limits remain those published by the Department of Agriculture and Food: up to 113 grams of unprocessed flower and 20 grams of THC in other products, if a provider authorizes that maximum. Home growing remains prohibited. New federal hemp limits begin November 12 and December 11, 2026.
