CHAPTER 30. IMPUTATION OF OFFENSE ELEMENTS
Section 31 – Voluntary Intoxication

(a) Except as provided in Section 54 (Involuntary Intoxication) or

Subsection (b), evidence of a person’s intoxication at the time of committing an

offense is admissible to negate a required culpability element of the offense.

(b) Imputation of Recklessness. If, due to voluntary intoxication, a

person is unaware of a risk of which he would have been aware had he been

sober, recklessness as defined in Section 24(e) is imputed to him.

(c) Voluntary Intoxication. Intoxication is voluntary if it is:

(1) caused by substances that the person knowingly introduces

into his body, being reckless as to the resulting intoxication, unless the

person introduces the substances pursuant to medical advice or under

such circumstances as would afford a justification or excuse defense;

and

(2) not grossly excessive in degree, given the amount of the

intoxicant, to which the person does not know and could not reasonably

be expected to know he is susceptible.(d) Definition. “Intoxication” means a disturbance of mental or physical

capacities resulting from the introduction of substances into the body.

CHAPTER 50. EXCUSE DEFENSES
Section 54 – Involuntary Intoxication

consequences of his conduct constituting the offense, or

(2) to appreciate the wrongfulness of his conduct constituting the

offense, or

(3) to control his conduct constituting the offense so as to be

justly held accountable for it.

(b) Involuntary Intoxication. Intoxication is involuntary if it is:

(1) caused by substances that the person did not knowingly

introduce into his body, or

(2) grossly excessive in degree, given the amount of intoxicant, to

which he does not know and could not reasonably be expected to know

he is susceptible.
