A. Intoxication of the accused is not a defense to any Parachute criminal offense, except as provided in subsection (B) of this section.

B. A person is not criminally responsible for his conduct if, by reason of intoxication that is not self-induced at the time he acts, he lacks capacity to conform his conduct to the requirements of the law.

C. “Intoxication” as used in this section means a disturbance of mental or physical capacities resulting from the introduction of any substance into the body.

D. “Self-induced intoxication” means intoxication caused by substances which the defendant knows or ought to know have the tendency to cause intoxication and which he knowingly introduced or allowed to be introduced into his body, unless they were introduced pursuant to medical advice or under similar circumstances that would afford a defense to a criminal offense.
