Overview

South Dakota enforces a zero-tolerance standard for cannabis and driving. Any detectable amount of THC in a driver's system constitutes a violation. South Dakota has a medical cannabis program but recreational cannabis remains illegal after legalization efforts were struck down by the state Supreme Court.

The zero-tolerance approach applies to all THC, including inactive metabolites. South Dakota's implied consent law carries a 1-year license revocation for refusal, and first-offense penalties can be severe.
