South Dakota Cannabis FAQ

Common questions about South Dakota marijuana laws, cannabis history, and 2026 updates.

Medical marijuana has been legal in South Dakota since Measure 26 took effect in July 2021. Recreational cannabis is not legal — a separate 2020 measure, Amendment A, was struck down by the state Supreme Court in 2021, and later recreational ballot measures in 2022 and 2024 were also rejected by voters.

Voters approved Amendment A, a recreational marijuana measure, in November 2020, but the South Dakota Supreme Court struck it down in November 2021 for violating the state constitution's single-subject rule for ballot amendments.

Patients need a qualifying debilitating medical condition and certification from a practitioner to register with South Dakota's medical marijuana program.

South Dakota's medical marijuana law allows registered patients to grow a limited number of plants for personal use if they live in a jurisdiction that does not have a licensed dispensary within a set distance.
