No. 14 – The South Dakota Controlled Substances Act: Legislative Architecture, Intent, and Institutional Design in a Potential Federal Rescheduling Context

The South Dakota Controlled Substances Act: Legislative Architecture, Intent, and Institutional Design in a Potential Federal Rescheduling Context

By Jason Karimi | WeedPress Policy Series No 14 March 24, 2026

I. Introduction

As previewed in WeedPress White Paper No. 1, South Dakota adopted its Controlled Substances Act (“CSA”) in 1970 as part of a broader national movement toward uniform drug regulation.¹ Enacted in the same year as the federal Comprehensive Drug Abuse Prevention and Control Act,² the South Dakota statute codified a structured scheduling framework within Title 34, Chapter 20B of the South Dakota Codified Laws.³

The statute reflects deliberate legislative alignment with the federal model while preserving independent state authority over criminal classification and rescheduling. Its institutional design becomes particularly significant in light of potential federal rescheduling of cannabis.

II. Original Enactment and Legislative Alignment

South Dakota’s Controlled Substances Act was enacted through 1970 Session Laws, chapter 229, section 6.⁴ The timing is notable: South Dakota adopted its statute in the same year Congress enacted the federal CSA.⁵

The state scheduling criteria mirror federal language. Schedule I substances must have:

(1) A high potential for abuse;
(2) No accepted medical use in treatment in the United States; and
(3) A lack of accepted safety for use under medical supervision.⁶

This language closely parallels 21 U.S.C. § 812(b)(1).⁷ The parallel drafting reflects legislative intent to harmonize state and federal drug classification standards at the level of definitional criteria.

South Dakota did not create a novel framework. It adopted a uniform structure while retaining state control over implementation.

⸻

III. Institutional Design: Legislative Retention of Rescheduling Authority

The most structurally significant feature of South Dakota’s CSA appears in SDCL § 34-20B-27, which provides:

“New legislation is required. The Department of Health makes recommendations to the Legislature to add, delete or reschedule a substance when the Department determines that the substance has a different potential for abuse.”⁸

This language confirms that South Dakota did not vest unilateral rescheduling authority in an executive official.

Unlike the federal model — where scheduling authority is delegated to the Attorney General subject to binding scientific and medical findings from the Secretary of Health and Human Services⁹ — South Dakota retained final authority within the Legislature.

The structure operates as follows:

1. The Department of Health evaluates abuse potential.
2. The Department may recommend changes.
3. The Legislature must enact new legislation to effectuate any rescheduling.

This is a legislative-control model, not an administrative-delegation model.

⸻

IV. Abuse Potential as the Procedural Trigger

Section 34-20B-27 centers “different potential for abuse” as the trigger for legislative reconsideration.¹⁰

This differs from the federal eight-factor analysis codified at 21 U.S.C. § 811(c),¹¹ which includes scientific evidence, pharmacological effect, and public health risk among its considerations.

Under South Dakota law:

• Medical acceptance is part of the definitional criteria for Schedule I.¹²
• Abuse potential is the statutory catalyst for legislative reconsideration.¹³

The Legislature thus structured rescheduling as a formal legislative act informed by health expertise, not an automatic administrative update.

⸻

V. Cannabis and the Dual-Structure Model

Cannabis remains listed as a Schedule I substance under SDCL § 34-20B-16.¹⁴

In 2020, South Dakota voters approved Initiated Measure 26, establishing a regulated medical cannabis framework codified in Chapter 34-20G.¹⁵

The result is a layered statutory system:
• Cannabis remains classified as Schedule I in Chapter 34-20B.
• Medical use is permitted under Chapter 34-20G.

The Legislature did not remove cannabis from Schedule I when implementing the medical program. Instead, it created a regulatory carve-out within a continuing Schedule I framework.

This layering preserves the original classification architecture while accommodating voter-approved medical use.

⸻

VI. Structural Implications in a Federal Rescheduling Context

If federal authorities determine that cannabis has “currently accepted medical use,” the federal Schedule I criteria under 21 U.S.C. § 812(b)(1) would no longer apply at the federal level.¹⁶

South Dakota’s statute does not automatically adjust.

Under § 34-20B-27:

• The Department of Health may recommend change.
• The Legislature must enact new legislation.

This legislative retention model exemplifies the “static mirror” category discussed in WeedPress White Paper No. 1, where federal medical recognition creates textual exposure without automatic adjustment.

Federal rescheduling would therefore not trigger automatic state modification. The issue would become legislative coherence rather than administrative preemption.

⸻

VII. Conclusion

South Dakota’s Controlled Substances Act reflects:

• Early alignment with the federal 1970 CSA;
• Adoption of uniform scheduling criteria;
• Legislative retention of rescheduling authority;
• Structural separation between advisory health expertise and criminal classification power.

The inclusion of § 34-20B-27 confirms that South Dakota intended scheduling changes to occur through formal legislative action, not executive modification.

In a potential federal rescheduling context, that institutional choice becomes central.
