S.D. Codified Laws § 26-8A-34
If the court finds the apparent, alleged, or adjudicated abuse or neglect of a child was related to the use of alcohol, marijuana, or any controlled drug or substance, the placement or return of the child may be subject to the condition, if the court so orders, that a parent, guardian, custodian, or any other adult residing in the home submit to tests for alcohol, marijuana, or any controlled drug or substance prior to or during the placement or return of the child. If a parent, guardian, custodian, or any other adult, who resides in the home and has been ordered by the court to submit to testing for alcohol, marijuana, or any controlled drug or substance, tests positive for alcohol, marijuana, or any controlled drug or substance, or fails to submit to the test as required, the Department of Social Services may immediately remove the child from the physical custody of the parent, guardian, or custodian, without prior court order, subject to a review hearing, which may be telephonic, within forty-eight hours excluding Saturdays, Sundays, and court holidays. As used in this section, any controlled drug or substance means a controlled drug or substance which was not lawfully prescribed by a practitioner as authorized by chapters 22-42 and 34-20B.
