Is recreational marijuana legal in South Dakota?

Recreational marijuana is currently illegal in South Dakota. Despite a 2020 voter-approved measure, courts blocked its implementation, and state law prohibits recreational use.

Amendment A invalidation: The state Supreme Court struck down the 2020 legalization measure, preventing recreational marijuana sales and possession.
Federal law conflict: Marijuana remains illegal federally, which complicates enforcement but does not change state prohibitions in South Dakota.
Ongoing legislative efforts: Lawmakers continue to debate recreational legalization, but no new laws have passed to permit adult use as of 2024.

Until new legislation or court rulings occur, recreational marijuana possession and use remain illegal and subject to criminal penalties in South Dakota.
