Ohio cannabis law: what's legal, what's not, and what changed.

Is cannabis legal in Ohio?

Yes. Ohio voters approved Issue 2 on November 7, 2023, legalizing cannabis for adults 21 and older. The legislature then rewrote the law with Senate Bill 56, signed on December 19, 2025 and in effect since March 20, 2026. Today both the adult-use and medical programs sit under Ohio Revised Code Chapter 3796, and both are regulated by the Ohio Division of Cannabis Control.

Legal doesn't mean anything goes. The rules on where you can buy, use, carry and grow cannabis are specific, and they're enforced.

How much cannabis can you possess in Ohio?

Adults 21 and older may possess up to:

• 2.5 ounces of cannabis in any form other than extract, and
• 15 grams of cannabis extract.

Since Senate Bill 56, those limits only cover cannabis bought from a licensed Ohio dispensary or grown legally at home in Ohio. Carrying more than the limit, or cannabis from anywhere else, can still be charged as a possession offense. Read our full guide to Ohio cannabis possession limits.

Medical and adult-use cannabis in Ohio

Ohio runs its medical program alongside adult-use, and every Bloom in Ohio serves both. The daily purchase limits are the same for everyone. Registered patients get a few things adult-use customers don't:

• No 10% adult-use excise tax on medical purchases.
• The option to buy up to four days' supply in a single visit.
• Access as patients under 21. Patients 18 and older register on their own; patients under 18 need a parent or legal guardian registered as their caregiver.
• Some legal protections, such as in professional licensing and custody decisions, that Senate Bill 56 removed for adult-use consumers.

Medical cannabis can't be smoked or combusted, and patients under 18 can't use vaporization. Thinking about a patient card? Read about the Ohio medical marijuana card.

Where can you legally buy cannabis in Ohio?

Only at a dispensary licensed by the Division of Cannabis Control. Buying from an unlicensed seller, an online marketplace or another state is illegal. At the counter you'll need:

• A valid, unexpired government-issued photo ID, and
• To be 21 or older, or a registered Ohio medical patient or caregiver.

Intoxicating hemp products — including hemp THC drinks and delta 8 — are banned outside licensed dispensaries under Senate Bill 56. See delta 8 in Ohio and THC drinks in Ohio.

Where is cannabis use still illegal in Ohio?

Using cannabis in a public place is illegal. Smoking, combusting or vaping cannabis is only allowed on privately owned property used mainly as a home or farm. Even then, it isn't allowed:

• In a home that also operates as a childcare center.
• In a halfway house or similar community residential facility.
• In a rental if the lease prohibits it.
• In a vehicle — a passenger smoking or vaping in a moving vehicle commits a misdemeanor.

Driving under the influence of cannabis is illegal, and Ohio's impaired-driving law sets specific THC limits. See where you can use cannabis in Ohio and Ohio's cannabis DUI laws.

Can you grow cannabis at home in Ohio?

Yes, within limits. Adults 21 and older can grow:

• Up to 6 plants per adult, and
• Up to 12 plants per household with two or more adults.

Plants must be kept in a secured, enclosed area that people under 21 can't access and that can't be seen from a public space. You can't sell homegrown cannabis, grow it for someone else, or process it with hydrocarbon-based extraction. Senate Bill 56 also bans home grow at childcare centers, halfway houses and similar facilities. More in our guide to growing cannabis at home in Ohio.

Transporting cannabis and travelling

Senate Bill 56 added clear rules for carrying cannabis in a car:

• An opened container goes in the trunk — or, with no trunk, behind the last upright seat or somewhere the driver and passengers don't normally sit.
• Paraphernalia follows the same rule.
• Edibles stay in their original packaging when you're not using them.

Cannabis must stay in Ohio. Crossing a state line with it is illegal, even into another state where it's legal.

How federal law fits in

Cannabis is legal under Ohio law but still illegal under federal law. Federal rules matter most when cannabis crosses state lines, on federal property such as airports and national parks, and in some federally regulated jobs and federally assisted housing.

What Senate Bill 56 changed

Senate Bill 56 took effect on March 20, 2026. The biggest changes for customers:

• Ohio-only cannabis. Legal cannabis must come from an Ohio dispensary or a legal Ohio home grow.
• Intoxicating hemp banned. Hemp THC drinks, gummies and similar products can no longer be sold outside licensed dispensaries.
• New transport and storage rules for cars and edibles, as above.
• Tighter rules on where you can smoke or vape, including in rentals and as a passenger.
• Fewer protections for adult-use consumers; medical patients keep theirs.
• Delivery for medical patients only, once the Division of Cannabis Control writes the rules. Bloom is pickup and pre-order only for now.

The full breakdown is in Senate Bill 56, explained.

What's still illegal in Ohio?

Penalties still apply for:

• Possessing more than the legal limit, or cannabis not bought or grown in Ohio.
• Selling cannabis, or growing it to sell, without a license.
• Using cannabis in public, or smoking or vaping where it's not allowed.
• Driving under the influence.
• Selling or giving cannabis to anyone under 21.
• Using false ID, or asking someone else to buy cannabis for you.
