Ohio’s strangulation law, codified at Ohio Revised Code 2903.18, makes it a standalone felony to knowingly impede another person’s breathing or blood circulation by applying pressure to the throat or neck or by covering the nose and mouth. The offense took effect on April 4, 2023 under Senate Bill 288, and depending on the harm involved a conviction runs from a fifth-degree felony carrying six to twelve months in prison up to a second-degree felony carrying two to eight years. Before the statute existed, prosecutors had to fit strangulation into broader assault charges that required proof of serious physical harm, a bar that was hard to clear because strangulation often leaves no marks.
What the Statute Prohibits
ORC 2903.18 covers any act that impedes normal breathing or blood circulation by pressure on the throat or neck, or by covering the nose and mouth. Three prohibited acts sit inside the statute, each keyed to a different level of harm:
- Knowingly causing or creating a substantial risk of physical harm through strangulation or suffocation.
- Knowingly creating a substantial risk of serious physical harm through strangulation or suffocation.
- Knowingly causing serious physical harm through strangulation or suffocation.
“Knowingly” is the mental state the prosecution has to prove. That’s a lower bar than intent to kill or intent to injure. The state has to show the accused deliberately engaged in conduct that restricted breathing or blood flow. Bumping someone’s neck during a fall wouldn’t qualify. Pressing on a throat during an argument would, even if the accused says they didn’t mean any real harm.
Visible injuries are not required. The legislative analysis behind SB 288 pointed out that charging strangulation under the old felonious assault framework was difficult precisely because that statute “imposes a standard of ‘serious physical harm'” that rarely showed up on the skin. The new law was written around that problem. A case can move forward even when the neck looks untouched.
That reflects the medical reality. Strangulation can cause carotid artery dissection, stroke, and acquired brain injury without leaving external bruising, and vascular damage from a single incident can remain a risk for up to twelve months afterward. Forensic exams look for petechiae, swelling in soft tissues and mucous membranes, and damage to internal structures like the hyoid bone and thyroid cartilage. A hoarse voice, difficulty swallowing, or bloodshot eyes can corroborate an account without a mark on the neck.
The Three Felony Tiers
The penalty depends on which of the three prohibited acts the state proves. Prison ranges come from ORC 2929.14 and fine caps from ORC 2929.18.
- Fifth-degree felony: causing or creating a substantial risk of physical harm by strangulation. Six to twelve months in prison and a fine of up to $2,500.
- Third-degree felony: creating a substantial risk of serious physical harm by strangulation. Nine to thirty-six months and a fine of up to $10,000.
- Second-degree felony: causing serious physical harm by strangulation. Two to eight years and a fine of up to $15,000.
The line between the fifth-degree and third-degree tiers turns on the difference between “physical harm” and “serious physical harm.” Ohio defines serious physical harm to include injuries that create a substantial risk of death, cause permanent disfigurement, or involve prolonged loss of a bodily function. Brief discomfort sits in the fifth-degree tier. Lasting neurological damage or a real risk of death sits in the second-degree tier.
How a Domestic Setting Changes the Case
The statute specifically defines “family or household member” and “dating relationship.” Lawmakers built the offense with domestic violence in mind. The practical effect is straightforward: conduct that used to be prosecuted as first-degree misdemeanor domestic violence under ORC 2919.25, carrying a maximum of 180 days in county jail, can now be charged as at least a fifth-degree felony under ORC 2903.18. Prison time enters the picture where it wasn’t before.
Prior convictions compound the exposure. A history of domestic violence, assault, or similar offenses gives prosecutors room to argue for longer terms within the statutory range, and judges weigh criminal history heavily when setting bail and evaluating plea offers. A pattern of escalating violence in an intimate relationship makes probation or minimum sentences less realistic.
Defenses
The most direct defense is that the act didn’t happen or has been mischaracterized. Because strangulation often leaves no visible evidence, these cases frequently come down to testimony. Defense attorneys look for inconsistencies in the accuser’s account, contradictory statements to police, and any surveillance footage, texts, or witnesses that cut against the state’s version. Medical records work both ways. A forensic exam that found no internal indicators of strangulation, combined with symptoms consistent with another cause, can undercut the case.
Self-Defense
Ohio recognizes self-defense even where the force could be described as strangulation. Under ORC 2901.05, the burden of disproving self-defense is on the prosecution. Once the defense puts forward evidence suggesting the accused acted in self-defense, the state has to prove beyond a reasonable doubt that the force was not justified. The defendant doesn’t have to prove self-defense by a preponderance of the evidence. They have to raise the issue credibly.
Raising it credibly still takes evidence: injuries on the defendant, documented threats from the alleged victim, a history of violent behavior by the alleged victim, or witnesses to how the altercation started. The force also has to have been proportional. A prolonged chokehold during a purely verbal argument is a hard sell.
Lack of Intent
Because the statute requires that the accused acted “knowingly,” an accidental-contact defense can work when the facts support it. If two people were struggling and neck contact happened incidentally rather than deliberately, the state’s case weakens. Expert medical testimony matters here. A doctor who can explain that the injuries look more like a fall or another impact than intentional pressure on the neck creates room for reasonable doubt on the mental state.
Consequences Beyond the State Sentence
A conviction under ORC 2903.18 carries collateral consequences that can outlast any prison term.
Firearm Prohibition
Federal law under 18 U.S.C. § 922(g) prohibits anyone convicted of a felony punishable by more than one year of imprisonment from possessing, shipping, or receiving firearms or ammunition. Every tier of Ohio’s strangulation statute is a felony, so any conviction triggers this ban. Even a fifth-degree felony qualifies, because Ohio’s sentencing framework makes it punishable by imprisonment exceeding one year when consecutive sentences and post-release control violations are taken into account. Violating the federal ban is a separate federal crime.
If the strangulation was committed against a current or former spouse, cohabiting partner, or co-parent, the federal prohibition at 18 U.S.C. § 922(g)(9) for misdemeanor crimes of domestic violence can also come into play for related charges arising from the same incident.
Immigration
Non-citizens face particularly severe stakes. Under 8 U.S.C. § 1227, any person convicted of a “crime of domestic violence” after admission to the United States is deportable. Federal law defines that term broadly to cover any crime of violence committed against a current or former spouse, cohabiting partner, co-parent, or anyone protected under domestic or family violence laws. A strangulation conviction in a domestic setting fits squarely within that definition. A conviction classified as an aggravated felony under immigration law can separately trigger mandatory removal with very limited relief.
Employment and Licensing
A felony record creates lasting barriers in Ohio. ORC 2953.25 provides a certificate of qualification for employment that can lift some automatic bars, but it doesn’t reach every restriction. Healthcare professionals, law enforcement officers, and prosecutors face specific exclusions the certificate cannot override. Private employers commonly run background checks, and a violent felony conviction substantially limits work in education, childcare, and any field that requires security clearances.
Protection Orders That Ride Along
Ohio courts can restrict contact with the alleged victim through two different types of orders.
A criminal protection order is issued through the court handling the criminal case and stays in effect for the duration of the prosecution. It can prohibit all contact with the victim, require the accused to stay away from the victim’s home or workplace, and restrict firearm possession. Judges often impose these at arraignment, so the order can take effect before trial.
A domestic violence civil protection order is obtained separately through the Common Pleas Court’s domestic relations division and does not require criminal charges. The petitioner has to show a credible threat by a preponderance of the evidence. These orders can last up to five years and are renewable, and judges can grant emergency temporary orders before the full hearing.
Violating any protection order is a separate offense under ORC 2919.27. A first violation is a first-degree misdemeanor. Prior protection order violations or related convictions push the charge to a fifth-degree felony. A violation committed while committing another felony is a third-degree felony. Under the federal Violence Against Women Act, 18 U.S.C. § 2265, an Ohio protection order is enforceable in every other state.
