(1) The fact that a person charged with an offense was in an intoxicated condition at the time the alleged offense was committed is a defense only if such condition was involuntarily produced and rendered such person substantially incapable of knowing or understanding the wrongfulness of his conduct and of conforming his conduct to the requirements of law.

(2) An act committed while in a state of voluntary intoxication is not less offensive by reason thereof, but when a particular intent or other state of mind is a necessary element to constitute a particular offense, the fact of intoxication may be taken into consideration in determining such intent or state of mind. (Ord. 83-75 § 2, 1983.)
