(a) No person, purposely or knowingly, and when purpose or knowledge is sufficient culpability for the commission of an offense, shall engage in conduct that, if successful, would constitute or result in the offense.
(b) It is no defense to a charge under this section that, in retrospect, commission of the offense that was the object of the attempt was either factually or legally impossible under the attendant circumstances, if that offense could have been committed had the attendant circumstances been as the actor believed them to be.
(c) No person who is convicted of committing a specific offense or of complicity in the commission of an offense, shall be convicted of an attempt to commit the same offense in violation of this section.
(d) It is an affirmative defense to a charge under this section that the actor abandoned the actor’s effort to commit the offense or otherwise prevented its commission, under circumstances manifesting a complete and voluntary renunciation of the actor’s criminal purpose.
(e) Whoever violates this section is guilty of an attempt to commit an offense. An attempt to commit a drug abuse offense for which the penalty is determined by the amount or number of unit doses of the controlled substance involved in the drug abuse offense is an offense of the same degree as the drug abuse offense attempted would be if that drug abuse offense had been committed and had involved an amount or number of unit doses of the controlled substance that is within the next lower range of controlled substance amounts than was involved in the attempt. An attempt to commit any other misdemeanor is a misdemeanor of the next lesser degree than the misdemeanor attempted. In the case of an attempt to commit an offense other than a violation of Ohio R.C. Chapter 3734 that is not specifically classified, an attempt is a misdemeanor of the first degree if the offense attempted is a felony under the Ohio Revised Code, and a misdemeanor of the fourth degree if the offense attempted is a misdemeanor. An attempt to commit a minor misdemeanor is not an offense under this section.
(f) As used in this section, “drug abuse offense” has the same meaning as in Ohio R.C. 2925.01. (ORC 2923.02)
