Unauthorized Ingestion of a Controlled Substance in South Dakota: Felony Charges Explained
In South Dakota, having unauthorized drugs in your system is a serious crime under SDCL § 22-42-5.1. A positive urine or blood test can support a conviction without physical drugs present, and repeat offenses escalate to a Class 6 Felony.
South Dakota is known for having some of the most aggressive and unforgiving drug laws in the entire United States. While most states only criminalize the physical possession of illegal drugs, South Dakota takes it a dramatic step further. Here, merely having a controlled substance in your body is treated as a severe crime. If you are pulled over, arrested for an unrelated offense, or subjected to a probation search, a positive drug test can immediately result in criminal charges.

The Ingestion Law: SDCL § 22-42-5.1
Under SDCL § 22-42-5.1, it is illegal to knowingly ingest or have an unauthorized controlled drug or substance in the body. This applies to substances like cocaine, methamphetamine, heroin, and unauthorized prescription painkillers. A first or second offense is classified as a Class 1 Misdemeanor, punishable by up to 1 year in jail and a $2,000 fine, with mandatory substance abuse evaluation. However, a third or subsequent conviction within 10 years escalates to a Class 6 Felony carrying up to 2 years in prison and a $4,000 fine under SDCL § 22-6-1(9). The state does not need to catch you in the act of consuming the drug. Law enforcement agencies, such as the Minnehaha County Sheriff's Office, Sioux Falls and the Pennington County Sheriff's Office, Rapid City, routinely use court-ordered urinalysis (UA) or blood draws to secure convictions.
Physical Possession vs. Internal Ingestion
In most jurisdictions, if the police search your car and find nothing, you are free to go. In South Dakota, the legal definition of a crime extends to your bloodstream. You could be charged with physical possession under SDCL § 22-42-5 if drugs are found in your pocket, and simultaneously charged with ingestion under SDCL § 22-42-5.1 if those drugs are found in your system. The precedent set in State v. Schroeder, 674 N.W.2d 827 (SD Supreme Court 2004) illustrates how South Dakota courts view the body as a vessel, allowing ingestion to be treated as a distinct and punishable offense. This dual-charge strategy is heavily utilized by prosecutors at the Minnehaha County Circuit Court, Sioux Falls to force plea deals.
How This Law Uniquely Traps Out-of-State Tourists
This law creates a terrifying scenario for out-of-state visitors. Imagine consuming a legal substance in a neighboring state like Colorado, or at a private party in California. Days later, you drive through South Dakota. If you are pulled over and the police establish probable cause to test your blood, you can be arrested for ingestion. South Dakota prosecutors often argue that your presence in the state with the substance in your body provides sufficient jurisdiction for criminal prosecution. A local attorney will aggressively challenge this jurisdictional overreach by arguing the state cannot prove the ingestion actually occurred within South Dakota borders.
Defending Against False-Positive Urine and Blood Tests
Your attorney's first line of defense is attacking the science and the procedure behind the drug test. Urine tests are notoriously prone to false positives due to over-the-counter medications, dietary supplements, or improper calibration of testing equipment at the South Dakota Public Health Laboratory, Pierre. Furthermore, if the police failed to establish sufficient probable cause to demand a bodily fluid sample, or if they coerced your consent without reading you your constitutional rights, a lawyer can file a motion to suppress the test results entirely. Without the test results, the state generally has no case.
Penalties and Costs for Ingestion Charges
While initial offenses are treated as misdemeanors, repeat convictions or felony enhancements in South Dakota carry life-altering consequences, including the potential loss of voting rights and firearm privileges.
| First or Second Offense | Class 1 Misdemeanor (up to 1 year in jail, $2,000 fine) |
| Third Offense (Within 10 Years) | Class 6 Felony (up to 2 years in prison, $4,000 fine) |
| Mandatory Treatment & Testing | Substance abuse evaluation and urinalysis monitoring |
| Attorney Defense Fees | Typically $2,500 to $7,500+ |
Frequently Asked Questions (FAQ)
Can I refuse a urine or blood test if I am arrested?
If you refuse, law enforcement can apply for an emergency search warrant from a judge. If the warrant is granted, they can physically force a blood draw. Refusal may also lead to separate penalties regarding your driving privileges if the stop involved a DUI suspicion.
Will I go to prison for a first-time ingestion offense?
A first-time offense under SDCL § 22-42-5.1 is classified as a Class 1 Misdemeanor rather than a felony, punishable by up to 1 year in county jail instead of state prison. First-time offenders are often eligible for probation or a suspended imposition of sentence, provided they complete court-ordered drug treatment.
Can a prescription from my home state protect me?
Yes. If you have a valid, unexpired prescription for the controlled substance (such as Adderall or Oxycodone) from a licensed physician in any state, you cannot be legally convicted of unauthorized ingestion.
How long do controlled substances stay in my system?
Depending on the substance and your metabolism, drugs like cocaine and meth can appear in urine tests for 3 to 5 days, while marijuana can linger for weeks, making travelers highly vulnerable.
