Many of the prohibitions for open carry apply to concealed carry in Ohio. Under the new law, you must be at least 21 years old to carry a concealed weapon, and you cannot have a conviction/pending prosecution for: any felony, any domestic violence, any drug offense (other than a minor misdemeanor), or negligent assault, or falsification of concealed handgun license [any] misdemeanor offense within the past three years of violence, which are the following offenses: Assault, Aggravated Menacing, Menacing by Stalking, Menacing, Arson, Inciting Violence, Riot, Inducing Panic, Endangering Children, Intimidation of attorney, victim, or witness to criminal case, or Escape for two or more charges of either Assault or Negligent Assault, or attempted Assault or attempted Negligent Assault [within the last 5 years] resisting arrest in the past 10 years You cannot be a fugitive, have a pending Civil Protection Order or Temporary Protection Order (from any state – not just Ohio), been found mentally incompetent by a court, have a suspended concealed carry license, or be drug or alcohol dependent. Dishonorable military discharges may prevent you from being able to carry a concealed weapon, as can your immigration status.
