Side by side
Ohio runs two legal systems out of the same stores. Medical cannabis is governed by the patient program; adult-use cannabis is open to anyone 21 or older. Both now sit in Ohio Revised Code Chapter 3796, after Senate Bill 56 merged the old adult-use chapter into it on March 20, 2026.
| Rule | Medical patient | Adult-use consumer |
|---|---|---|
| Age | No minimum; minors need parental consent and a registered caregiver | 21 or older |
| What you need | Yearly recommendation from a CTR physician and an active registration ($0) | Proof of age 21+ |
| 10% adult-use excise | Exempt | Charged, plus state and local sales tax |
| Daily purchase limit | 2.5 oz plant material and 15,000 mg total THC in other products | 2.5 oz plant material, 15,000 mg total THC in other products, 6 seeds, clones or live plants |
| Buying ahead | Up to four days' worth in one transaction (patients, not caregivers) | No bulk option described in DCC guidance |
| Possession | Up to a 90-day supply (14.06 lb plant material and 1,350 g total THC in other products) | 2.5 oz plant material and 15 g extract |
| THC caps (SB 56) | 35% for plant material, 70% for extracts, set in ORC 3796.06(E) | |
| Edibles | Must stay in original packaging when not in use | |
| Smoking or combustion | Prohibited for medical marijuana | Allowed only on private residential or agricultural property |
| Vaporizing | Private residential or agricultural property only; not for patients under 18 | Private residential or agricultural property only |
| Home grow | No medical home grow; patients 21+ follow adult-use rules | 6 plants per adult, 12 per household (DCC FAQ) |
| Where to buy | Licensed dual-use dispensaries | |
| Job protection | None under ORC 3796.28 | |
The adult-use limits come from the DCC FAQ. The four-day bulk purchase is described only for patients, which is why the adult-use cell says no bulk option.
Where medical still wins
- The excise. Medical purchases skip the 10% adult-use excise. On steady monthly buying, that adds up. Our Ohio cost calculator shows the yearly figure for your spend.
- Stocking up. Four days' worth per trip and a 90-day possession ceiling suit patients who live far from a dispensary.
- Age. Patients aged 18 to 20, and minors with a caregiver, have no other legal route.
- Some legal protections. Under ORC 3796.24, lawful medical use cannot be the sole or primary basis for a custody finding, a denial of medical care or a transplant-list spot, or asset forfeiture. Patient status alone also cannot be the reason a landlord turns you down.
Where adult-use is simpler
- No yearly visit. The physician visit is the one real cost of a card, and you pay it every year.
- Smoking. Medical marijuana may not be smoked or combusted at all. Adult-use cannabis may be smoked on private residential or agricultural property. Our guide to whether Ohio patients can smoke goes through this carefully.
- No paperwork to lapse. There is no registration to renew.
Is the card still worth it? An honest answer
For a light, occasional buyer over 21, maybe not. If you spend little each month, 10% of it may not cover a yearly visit, and the medical rules add a smoking ban you would not face as an adult-use buyer.
For a regular buyer, a patient under 21, someone who needs to stock up, or a family managing a child's treatment with a caregiver, the card still does real work. Neither path protects your job: ORC 3796.28 lets employers fire for marijuana use either way, as our employment page explains.
Weigh it with your physician, not just a spreadsheet. A recommendation also means a medical professional has looked at your condition, which is a different thing from picking a product off a menu.
Need the recommendation part done?
In Ohio the physician starts your Registry file, so the visit comes first. Online evaluations are available for Ohio residents, and code DRWDY85872 takes 5% off. Registration itself is free.

Senate Bill 56 took effect on March 20, 2026. It set the THC caps and the edibles packaging rule shown above, kept the 10% excise, restated the public-use bans, and moved intoxicating hemp products into licensed dispensaries. Read what SB 56 changed for patients for the details we could verify.
Decided on the card?
The application checklist covers the physician visit and Registry activation. Then pick a store from the Ohio dispensary guide, which links the DCC's official map.
Questions people ask
Do I need a medical card to buy cannabis in Ohio?
Not if you are 21 or older. Adult-use sales began August 6, 2024. Anyone under 21 needs to be a registered patient, and minors also need a registered caregiver.
Can a medical patient grow plants at home?
There is no medical-specific home grow. Adults 21 and over, patients included, may grow under adult-use law: up to 6 plants per person and 12 per household, according to the DCC FAQ.
Do medical and adult-use customers shop at different stores?
No. Ohio's licensed dispensaries hold dual-use Certificates of Operation and serve both groups.
