Ohio marijuana laws let adults 21 and older possess up to 2.5 ounces of cannabis flower, hold up to 15 grams of extract, grow up to six plants at home, and buy from licensed dispensaries. Voters approved Issue 2 in November 2023, and adult use took effect on December 7 of that year. Senate Bill 56, which took effect March 20, 2026, reshaped the regulatory framework but kept the core consumer rules intact. Everything below reflects the law as it stands after that overhaul.
Possession, Home Grow, and Gifting Limits
The personal possession ceiling is 2.5 ounces of cannabis in any form other than extract, plus up to 15 grams of extract.1Ohio Legislative Service Commission. Ohio Revised Code 3780.36 – Limitations on Conduct by Adult Use Consumer That is what you can have on your person or under your control at any one time, and it is also the most you can buy from a dispensary in a single day.2Ohio Department of Commerce. Medical Marijuana Products and Daily Limits
Home cultivation is legal within tight boundaries. One adult can grow up to six plants at their primary residence. A household with two or more adults over 21 tops out at twelve plants total, no matter how many adults live there. Plants must sit in an enclosed, secured space such as a closet, room, or greenhouse. The area cannot be visible from any public space without aid, and no one under 21 can have access to it.
You can give cannabis to another adult without charge. The 2.5-ounce flower and 15-gram extract limits apply to gifts as well. You cannot advertise or promote the transfer publicly, and selling without a license is still illegal regardless of quantity.1Ohio Legislative Service Commission. Ohio Revised Code 3780.36 – Limitations on Conduct by Adult Use Consumer
Where You Can Legally Consume
Consumption is limited to private property where the owner allows it. Using cannabis anywhere other than private residential or agricultural property is a minor misdemeanor under state law, so parks, sidewalks, parking lots, and restaurant patios are all off-limits.3Ohio Legislative Service Commission. Ohio Revised Code 3796.06 – Consumption Restrictions
Ohio’s Smoke-Free Workplace Act treats smoking cannabis in enclosed public spaces and workplaces the same way it treats tobacco. Fines start at $100 and can reach $2,500, doubling for intentional violations, with each day of noncompliance counted as a separate offense.4Ohio Legislative Service Commission. Ohio Revised Code 3794.07 – Fines Hotels can and usually do prohibit cannabis on the property. If you are not at home, get permission before consuming.
Buying From a Dispensary
Retail adult-use sales launched in mid-2024 once existing medical dispensaries began receiving dual-use certificates of operation. The Division of Cannabis Control within the Ohio Department of Commerce licenses cultivators, processors, testing labs, and dispensaries.5Ohio Department of Commerce. Dual-Use and 10(B) Application FAQ Bring a valid government-issued ID showing you are at least 21; you will not get past the door without it.
Every adult-use purchase carries a 10 percent excise tax at the register.6Ohio Department of Taxation. Adult Use Marijuana Tax Standard sales tax stacks on top: Ohio’s state rate is 5.75 percent, and counties add between zero and 2.25 percent, putting combined sales tax somewhere between 6.5 and 8 percent depending on where you shop.7Ohio Department of Taxation. Sales and Use Tax Rate Map Total taxes on an adult-use purchase can reach roughly 18 percent in higher-tax counties.
Products sold at licensed dispensaries have to pass lab testing for potency, pesticide residue, heavy metals, mycotoxins, and microbial contamination. Retailers track every gram through the state’s seed-to-sale software.
One consumer-side change from Senate Bill 56 is worth flagging: the bill redefined “hemp” in a way that excludes most intoxicating delta-8 beverages and edibles from legal sale. Those products, previously found in gas stations and vape shops, are no longer legal to sell in Ohio.
How a Medical Card Still Helps
Medical patients and adult-use buyers share the same daily transaction cap of 2.5 ounces of plant material and 15,000 milligrams of total THC for non-plant products.2Ohio Department of Commerce. Medical Marijuana Products and Daily Limits The differences show up in bulk buying, taxes, and how much a patient can hold over time.
Patients can buy up to four days’ worth of product in one visit, which recreational buyers cannot. Over a 90-day window, a patient may possess up to 14.06 pounds of plant material or 1,350 grams of total THC in other products.2Ohio Department of Commerce. Medical Marijuana Products and Daily Limits And the 10 percent excise tax applies only to “adult use marijuana,” so medical purchases skip it.8Ohio Legislative Service Commission. Ohio Revised Code 3780.22 – Excise Tax For regular users in high-tax counties, the tax exemption alone can add up to real money over a year.
Driving and Cannabis
Ohio treats driving under the influence of cannabis the same as an alcohol-related OVI. You are over the per se limit if your blood shows THC at two nanograms per milliliter or higher, or your urine shows at least ten nanograms per milliliter.9Ohio Legislative Service Commission. Ohio Revised Code 4511.19 – Operating Vehicle Under the Influence of Alcohol or Drugs – OVI THC can stay detectable in blood and urine for days after use, so a regular consumer can test over the limit without feeling impaired.
A first OVI is a first-degree misdemeanor with a mandatory minimum of three days in jail (or completion of a driver intervention program), fines between $375 and $1,075, and a license suspension. Repeat offenses within ten years bring longer mandatory minimums, longer suspensions, and potential felony charges.
Consuming as a passenger while the vehicle is in operation is a third-degree misdemeanor carrying up to 60 days in jail, even if the vehicle is parked on a public road.10Ohio Legislative Service Commission. Ohio Revised Code 3796.99 – Penalties To move cannabis legally, keep it in a sealed container in the trunk or a locked compartment passengers cannot easily reach.
Employer and Landlord Rights
Ohio law is unusually protective of employers. Companies can keep drug-free workplace policies, run zero-tolerance drug testing, and fire employees who test positive, even for off-duty use that was lawful under state law.11Ohio Legislative Service Commission. Ohio Revised Code 3780.35 – Rights of Employer A worker fired under a qualifying drug-free workplace policy is treated as having been terminated for just cause and cannot collect unemployment.12Ohio Legislative Service Commission. Ohio Revised Code 3796.28 – Rights of Employer
You cannot sue an Ohio employer for discrimination, retaliation, or wrongful termination based on cannabis use. The statute specifically bars those claims. Employers with federal contracts face additional pressure because marijuana is still Schedule I federally, so zero-tolerance policies are entrenched in transportation, defense contracting, and health care.
Landlords have similar authority. A landlord can prohibit cannabis smoking and cultivation in a rental unit if the restriction is in the lease.13Ohio Legislative Service Commission. Ohio Revised Code 3796.06 – Forms of Marijuana A landlord cannot reject a prospective tenant solely for engaging in lawful marijuana activities unless federal law requires the rejection. Violating a lease restriction on cannabis can be grounds for eviction, so read your lease before growing plants or smoking at home.
Where Federal Law Still Reaches
Cannabis is a Schedule I controlled substance under federal law, and Ohio’s legalization does not touch that. Three practical consequences follow.
Ohio law explicitly does not authorize possession or use on federal land within the state.14Ohio Legislative Service Commission. Ohio Revised Code 3796.24 – Limitations National parks, VA medical centers, federal courthouses, military installations, and post offices all sit under federal jurisdiction, and even small amounts on that ground can trigger federal charges.
Carrying cannabis across state lines is a federal offense regardless of what either state’s law says. Distributing or possessing with intent to distribute less than 50 kilograms of marijuana carries up to five years in prison and fines up to $250,000 under federal law.15Office of the Law Revision Counsel. 21 USC 841 – Prohibited Acts Even personal-use quantities crossing into Pennsylvania, West Virginia, Kentucky, Indiana, or Michigan technically violate the statute. Leave products at home when you travel.
Banking is still awkward. Most banks and credit unions are federally insured and hesitant to serve cannabis businesses directly, which is why some dispensaries remain cash-only or offer limited payment options.
Penalties for Going Over the Limits
Exceeding the legal possession amount does not automatically mean prison, but penalties escalate quickly with weight:
- Up to about 100 grams over the limit: minor misdemeanor, $150 fine, no jail.
- 100 to 200 grams: misdemeanor, up to 30 days in jail and a $250 fine.
- 200 to 1,000 grams: fifth-degree felony, up to 12 months in prison and fines up to $2,500.16Ohio Legislative Service Commission. Ohio Code 2929.14 – Definite Prison Terms
- 1,000 to 5,000 grams: third-degree felony, up to 3 years in prison and fines up to $10,000.
- Above 20,000 grams: second-degree felony with mandatory minimums of 5 to 8 years.
Cultivation violations follow similar tiers, with small overages treated less severely than large-scale grows. The straightforward path is to stay within six plants per adult (twelve per household) and keep flower under 2.5 ounces.
Clearing an Old Marijuana Conviction
Ohio separates sealing from expungement. Sealing hides a conviction from public background checks while law enforcement keeps access. Expungement goes further and largely destroys the record. Either path starts with an application in the court that handled the original case, a $50 application fee per court, and up to $50 in court costs.17The Ohio State University Moritz College of Law. Ohio Criminal Record Relief Options
Waiting periods run from the date of final discharge and depend on the severity of the original conviction:
- Minor misdemeanor: 6 months for sealing or expungement.
- Misdemeanor: 1 year for sealing or expungement.
- Fourth- or fifth-degree felony: 1 year for sealing, 11 years for expungement.
- Third-degree felony: 3 years for sealing, 13 years for expungement.
Cases in multiple jurisdictions each need their own application. When a case has more than one charge, the longest applicable waiting period controls. Ohio Revised Code Section 2953.39 also lets prosecutors file motions to seal low-level controlled substance convictions, which can shortcut the process in some counties. For anyone still carrying an old marijuana possession charge from before legalization, the filing cost is small compared with what a clean record opens up.
