South Dakota 2026 cannabis ballot measure explained
There is no cannabis legalization measure on South Dakota’s November 3, 2026 ballot. The South Dakota Secretary of State’s 2026 ballot questions page, accessed October 29, 2026, lists four general election measures, Amendments I, J, K and L, and none of them deals with marijuana. Adult use cannabis remains illegal in South Dakota, and only registered medical patients have legal access under the state’s medical program. One measure does matter for future cannabis reform. Amendment L would require a constitutional amendment to receive 60 percent of the votes cast to pass, which would raise the bar for any future cannabis amendment. This guide explains where things stand as of October 29, 2026. It does not predict any result and is not legal advice. It is for adults 21 and older.
Election update (Nov 5 2026): Still no cannabis measure. Amendment L failed (about 57.6% no, unofficial SOS results), so the 60% threshold for future constitutional amendments did not pass.
What is on the 2026 ballot
According to the Secretary of State’s page, the four general election ballot measures are all constitutional amendments proposed by the 2025 Legislature:
| Letter | Topic per the official title |
|---|---|
| I | Conditioning the Medicaid expansion requirement on the level of federal medical assistance |
| J | Clarifying that an individual must be a U.S. citizen to vote |
| K | Establishing a trust for the unclaimed property fund |
| L | Requiring a constitutional amendment to receive 60 percent of votes cast to be enacted |
None of these legalizes, decriminalizes or changes cannabis rules. Some online articles have described a South Dakota marijuana amendment for 2026, but we could not find one on the official Secretary of State list. Always check the official source.
Why Amendment L matters for cannabis
Cannabis reform in South Dakota has often been pursued by citizen petition, and one of the past efforts was a constitutional amendment. Today, constitutional amendments in South Dakota pass with a simple majority. Amendment L would raise that threshold to 60 percent of the votes cast.
If Amendment L passes, any future cannabis legalization proposed as a constitutional amendment would need a larger share of the vote. Initiated laws, which change statutes rather than the constitution, are a separate path, so read the official explanation to see exactly what L covers. If Amendment L fails, the current simple majority rule stays. Read the Attorney General’s explanation on the Secretary of State’s site.
A short history of cannabis on the South Dakota ballot
South Dakota voters have seen several cannabis measures:
- 2020: Voters approved a medical marijuana law, Initiated Measure 26, and an adult use constitutional amendment, Amendment A. The South Dakota Supreme Court later struck down Amendment A, so adult use did not take effect. The medical program went forward.
- 2022: Initiated Measure 27, an adult use proposal, was on the ballot and did not pass.
- 2024: Initiated Measure 29, another adult use proposal, was on the ballot and did not pass.
- 2026: No cannabis measure is on the general election ballot, according to the official list.
Current South Dakota cannabis law
As of October 29, 2026:
- Adult use, or recreational, cannabis is not legal
- Possession without a medical card can lead to criminal penalties
- The state runs a medical cannabis program through the Department of Health
- Some registered patients may be allowed limited home cultivation under program rules, but only as their registration allows. Check the Department of Health for current rules
- Growing cannabis without proper registration is illegal
Federal law still treats marijuana as illegal. A federal hemp definition change takes effect on December 11, 2026 under a 2025 federal law, Public Law 119 37, that amended the hemp definition at 7 U.S.C. 1639o.

Why you may see conflicting information online
Election season brings a lot of articles, social posts and ads. Some describe measures that were proposed, approved for circulation or rumored, but never qualified for the ballot. Others mix up states or years. A petition approved for circulation is not the same as a measure on the ballot. Only measures certified by the Secretary of State appear on your ballot. When in doubt, compare any claim with the official list and your county’s sample ballot.
How to check your own ballot
- Visit the South Dakota Secretary of State’s elections pages.
- Look for the 2026 ballot question information and the pro and con pamphlet.
- Use the state’s voter information portal to view your sample ballot.
- Read each Attorney General explanation, which summarizes what a yes or no vote does.
- Contact your county auditor if anything is unclear.
Medical program basics
South Dakota’s medical cannabis program is run by the Department of Health. Patients need a qualifying condition, certification from a practitioner and a registration card. Cardholders can buy from licensed dispensaries within program limits. Rules on possession amounts, cultivation and caregivers are set by state law and department rules and can change. Check the department’s site for the current version before acting.
How a future cannabis measure could reach the ballot
South Dakota allows citizens to propose initiated laws and constitutional amendments by petition. Sponsors file the text, receive an Attorney General explanation, gather enough valid signatures by the deadline, and then the Secretary of State certifies the measure. The Legislature can also refer measures to voters. Any future cannabis measure would need to follow these steps, and the result of Amendment L may change the vote needed for an amendment.
Neighboring states
South Dakota borders states with a mix of cannabis laws. Some neighbors allow adult use and home growing, while others do not. Carrying cannabis across state lines is illegal, even between two legal states, and doing so can bring both state and federal charges.
