A person who is in an intoxicated or drugged condition is criminally responsible for conduct unless the condition either:
(A) Is so extreme as to suspend the power of reason and render him or her incapable of forming a specific intent which is an element of the offense; or
(B) Is voluntarily produced and deprives him or her of substantial capacity either to appreciate the criminality of his or her conduct or to conform his or her conduct to the requirements of law.
