Recreational THC is not legal in South Dakota as of 2026. Despite a 2022 voter‑approved constitutional amendment that called for future legalization, the state legislature has yet to enact the necessary statutes, and existing law still classifies recreational cannabis as a Schedule I controlled substance (South Dakota Codified Laws, 2024).
Current Legal Landscape
South Dakota’s Constitution now contains an amendment—often referred to as “Amendment A”—which obligates the Legislature to create a regulatory framework for adult‑use cannabis by January 1, 2024. The deadline passed without any bill becoming law, meaning the amendment’s language is effectively dead‑locked. Consequently, possession of any amount of THC for non‑medical purposes remains a misdemeanor punishable by up to a year in jail and a $2,000 fine (S.D. Rev. Stat. § 22‑42‑1). Medical marijuana, however, is permitted under the 2020 “Sarah L.” law, allowing qualifying patients to possess up to three ounces of usable cannabis.
Legislative Developments Since 2022
- 2023 Session: Lawmakers introduced two competing bills—HB 1010 (a tightly regulated market) and SB 212 (a more permissive framework). Both stalled in committee due to disagreements over taxation and local control (Rapid City Journal, 2023).
- 2024 Session: A bipartisan compromise, HB 305, was passed but vetoed by Governor Kristi Noem, who cited “public safety” concerns (Rapid City Journal, 2024).
- 2025 Session: The Legislature revisited the issue with a modest amendment to HB 305 that reduced the state excise tax from 25 % to 15 % and allowed counties to hold advisory referendums. The bill passed both chambers but was postponed pending a constitutional clarification from the South Dakota Supreme Court (South Dakota Supreme Court, 2025).
Potential Future Scenarios
- Legislative Passage in 2026: If the revised HB 305 is signed, the state could begin issuing licenses by mid‑2026, creating a market comparable to Colorado’s early years.
- Judicial Intervention: A ruling that the 2022 amendment is unenforceable would permanently block any future legislative attempts, keeping recreational THC illegal.
- Ballot Initiative: Advocates may pursue another voter referendum in the 2026 general election, a path that succeeded in 2020 for medical cannabis.
Regardless of the outcome, businesses and residents should continue to treat recreational THC as unlawful until the statutory framework is formally enacted and take effect.
FAQ
What penalties exist for possessing recreational THC in South Dakota in 2026?
Possession of any amount for non‑medical use is a Class B misdemeanor, punishable by up to one year in jail and a fine of up to $2,000 (S.D. Rev. Stat. § 22‑42‑1).
Can I use medical marijuana in South Dakota while waiting for recreational legalization?
Yes. Qualifying patients may possess up to three ounces of usable cannabis under the “Sarah L.” medical program, provided they have a state‑issued certification (South Dakota Department of Health, 2024).
Are there any cities or counties that have de‑criminalized THC independently?
No. Local jurisdictions lack authority to override state criminal statutes. Some counties have passed “non‑enforcement” resolutions, but they do not alter the legal consequences under state law.
How does South Dakota’s tax proposal compare to neighboring states?
The most recent legislative draft proposed a 15 % excise tax on retail sales, lower than Colorado’s 15 % state tax plus local taxes that often exceed 30 % total (Colorado Department of Revenue, 2023).
When is the next opportunity for voters to decide on recreational cannabis?
If the Legislature fails to act, advocates plan to place a new constitutional amendment on the 2026 general election ballot, following the successful 2020 medical‑marijuana referendum (South Dakota Secretary of State, 2025).
