Recreational Marijuana in South Dakota: Still Not Legal Despite Voter Approval

South Dakota remains one of the few states where recreational cannabis use is not legal, despite voters approving a ballot initiative in 2020. This complex legal landscape has significant implications for employer drug-free workplace policies and drug testing protocols.

While medical marijuana is legal under Measure 26, the recreational measure faced a successful legal challenge based on the state's single-subject rule. Employers must navigate these distinctions carefully to maintain compliance.

The rule, plainly stated

South Dakota's Recreational Marijuana Ban Sustained

In South Dakota, recreational marijuana use and possession remain illegal. Despite the passage of Initiated Measure 27 by voters in November 2020, the South Dakota Supreme Court struck down the measure in November 2021 in the case of Thom v. Barnett, citing a violation of the state's single-subject rule. This ruling effectively nullified the voter-approved legalization of recreational cannabis.

South Dakota Supreme Court Ruling: Thom v. Barnett, 2021 S.D. 70, 967 N.W.2d 446 (2021)

The Court found that Initiated Measure 27 violated Article XXI, Section 13 of the South Dakota Constitution, which requires that "No law shall embrace more than one subject, which shall be expressed in its title." The measure was deemed to contain multiple distinct subjects.

Medical Marijuana is Legal (Measure 26)

In contrast to recreational marijuana, medical marijuana is legal in South Dakota under Initiated Measure 26, also passed by voters in November 2020. This measure established a medical cannabis program for qualifying patients with debilitating medical conditions. Employers must be aware of the distinction and potential accommodation requirements for employees who are registered medical cannabis cardholders, though federal law continues to classify marijuana as an illegal substance.

Employer Drug-Free Workplace Policies

The invalidation of recreational marijuana legalization means that employers in South Dakota retain significant discretion in maintaining drug-free workplace policies. Employers are generally permitted to prohibit the use of recreational marijuana by employees and to conduct drug testing in accordance with established policies and procedures, without fear of violating state recreational cannabis laws. However, policies should be reviewed to ensure they do not inadvertently discriminate against medical cannabis patients where state law allows for limited protections.

Can employers in South Dakota still conduct drug testing for marijuana?

Yes, employers in South Dakota can generally continue to conduct drug testing for marijuana. Since recreational use is illegal, employers retain the right to enforce drug-free workplace policies. However, they should be mindful of potential accommodation requirements for employees with valid medical marijuana cards under Measure 26.

What was the reason for Measure 27 being struck down?

The South Dakota Supreme Court struck down Measure 27 because it violated the state's "single-subject rule." This constitutional rule requires that a ballot measure or law address only one topic, and the Court found that Measure 27 attempted to address multiple, distinct subjects.

However, if you have employees with medical marijuana cards, you may need to consider reasonable accommodations under Measure 26, depending on the role and safety considerations.

Yes, proponents of recreational marijuana legalization have made subsequent attempts to get new initiatives on the ballot, but as of early 2026, no new measure has successfully navigated the legal challenges and voter approval process to make recreational marijuana legal.
