Marijuana and Drugs
ORC 3796 — Marijuana Control Law
Ohio law changed twice. Voters legalized adult use marijuana in 2023, then Senate Bill 56 replaced that framework with the Marijuana Control Law in Chapter 3796, effective March 20, 2026. Anything written before that date describes a law that no longer exists.

- An adult 21 or over may possess up to 2.5 ounces of marijuana plant material and up to 15 grams of extract.
- Home grow is capped at 6 plants per adult, and 12 plants total for a residence no matter how many adults live there.
- Plants have to be in a secured, enclosed area that people under 21 cannot get into.
- Growing for someone else, or selling what you grew, is not covered by any of this.
In a vehicle it has to be in the sealed packaging it was sold in. Once that packaging is opened it belongs in the trunk, or behind the last upright seat if there is no trunk, somewhere the driver and passengers are not sitting and cannot easily reach.
Lawful to have is not lawful to use wherever you are standing. The control law carries its own prohibition on public use, separate from everything about quantity and packaging. A person can be entirely within the possession allowance and still be committing an offense by using it in the wrong place, which is the distinction people collapse most often after a law changes.
- Storing it wrong in a vehicle is a minor misdemeanor, a fine up to $150 and no jail.
- A passenger smoking or vaping while the driver is driving is a misdemeanor of the third degree.
- Legal to possess is not legal to drive on. Impairment is charged under the OVI statute regardless of what made you impaired.
Ohio courts genuinely disagree on this one. Whether the smell of marijuana alone still lets police search your car after legalization is unsettled, and it is now before the Ohio Supreme Court. The 2000 rule in State v. Moore held that odor alone was enough. Since legalization the appellate districts have split, and a decision of a district binds the trial courts within it, so the answer can turn on which part of Ohio you are standing in. The Odor Question sets out both positions and what the court has been asked.
State legal is not federally legal. Marijuana is still a Schedule I controlled substance under federal law. In April 2026 the Justice Department moved FDA approved marijuana products and state licensed medical marijuana to Schedule III, and opened hearings on rescheduling the rest. Adult use marijuana was not included and remains Schedule I. That matters on federal land, in federal court, and for anything touching firearms, immigration, public housing, or a federally regulated job.
Everything above is about marijuana specifically. Other controlled substances are charged under the general possession statute, where the degree depends on the drug and the amount. Paraphernalia is its own separate charge.
“I do not consent to any searches.”
This area moved twice in three years and is still moving. Anything written about Ohio marijuana law has a date that matters, and this page is no exception.
