S.D. Codified Laws § 22-5-5

22-5-5. Voluntary intoxication--Crimes involving motive or intent.

No act committed by a person while in a state of voluntary intoxication may be deemed less criminal by reason of such condition. But if the actual existence of any particular purpose, motive, or intent is a necessary element to constitute any particular species or degree of crime, the jury may take into consideration the fact that the accused was intoxicated at the time in determining the purpose, motive, or intent with which the accused committed the act.
