SDCL § 34-20A-63: Emergency detainment--Grounds.

An intoxicated person, or a person receiving treatment for withdrawal management, may be detained in an approved treatment facility for emergency treatment if the person:

(1) Has threatened, attempted, or inflicted physical harm on oneself or on another or is likely to inflict physical harm on another unless detained;

(2) Is incapacitated by the effects of alcohol or drugs; or

(3) Is pregnant and abusing alcohol or drugs.

A refusal to undergo treatment does not constitute evidence of lack of judgment as to the need for treatment.
