(a) Except as provided in division (b) of this section, a person is not guilty of an offense unless both of the following apply:
(1) The person's liability is based on conduct that includes either a voluntary act, or an omission to perform an act or duty that the person is capable of performing;
(2) The person has the requisite degree of culpability for each element as to which a culpable mental state is specified by the section defining the offense.
(b) When the section defining an offense does not specify any degree of culpability, and plainly indicates a purpose to impose strict criminal liability for the conduct described in the section, then culpability is not required for a person to be guilty of the offense. When the section neither specifies culpability nor plainly indicates a purpose to impose strict liability, recklessness is sufficient culpability to commit the offense.
(c) Voluntary intoxication may not be taken into consideration in determining the existence of a mental state that is an element of a criminal offense. Voluntary intoxication does not relieve a person of a duty to act if failure to act constitutes a criminal offense. Evidence that a person was voluntarily intoxicated may be admissible to show whether or not the person was physically capable of performing the act with which the person is charged.
(d) For the purpose of this section, the following definitions shall apply unless the context clearly indicates or requires a different meaning.
(1) "Culpability." Purpose, knowledge, recklessness or negligence, as defined in R.C. § 2901.22.
(2) "Intoxication." Includes but is not limited to intoxication resulting from the ingestion of alcohol, a drug, or alcohol and a drug.
(3) "Involuntary acts." Reflexes, convulsions, body movements during unconsciousness or sleep, and body movements that are not otherwise a product of the actor's volition are "involuntary acts".
(4) "Possession." A voluntary act if the possessor knowingly procured or received the thing possessed, or was aware of the possessor's control of the thing possessed for a sufficient time to have ended possession.
