Part 1- General
SELF-INDUCED INTOXICATION
33.1 (1) It is not a defence to an offence referred to in subsection (3) that the accused, by reason of self-induced intoxication, lacked the general intent or the voluntariness required to commit the offence, where the accused depart¬ed markedly from the standard of care as described in subsection (2).
(2) For the purposes of this section, a person departs markedly from the standard of reasonable care generally recognized in Canadian society and is thereby criminally at fault where the person, while in a state of self-induced intoxication that renders the person unaware of, or incapable of consciously controlling, their behaviour, voluntarily or involuntarily interferes or threatens to interfere with the bodily integrity of another person.
1. In addition to other grounds for excluding criminal responsibility provided for in this Statute, a person shall not be criminally responsible if, at the time of that person's conduct:
(b) The person is in a state of intoxication that destroys that person's capacity to appreciate the unlawfulness or nature of his or her conduct, or capacity to control his or her conduct to conform to the requirements of law, unless the person has become voluntarily intoxicated under such circumstances that the person knew, or disregarded the risk, that, as a result of the intoxication, he or she was likely to engage in conduct constituting a crime within the jurisdiction of the Court;
