States have found it difficult to address the problems created when a person drives under the influence of prescription drugs. As a result, different states have created very formulations of the prescription-drug defense. Iowa has adopted the most restrictive version of all when it enacted a statute prohibiting driving with any controlled substance in the body. This restrictive version of OWI was adopted because of the perceived difficulty in proving impairment at trial.
In essence, the Iowa legislature created a shortcut for prosecutors which eliminated the “impairment” requirement. This type of OWI charge is called the zero tolerance per se version of OWI for drug impairment (often called “OWID” “DUID” or “DWID” in other states). This OWI statute applies to marijuana, street drugs like cocaine and MDMA, and even prescription medication.

Types of OWI Charges in Iowa
Today, Iowa Code section 321J.2(1) has several different types of OWI charges including driving:
- While having an alcohol concentration of .08 or more.
- While under the influence of an alcoholic beverage or other drug or a combination of such substances.
- While any amount of a controlled substance is present in the person, as measured in the person’s blood or urine.
Iowa Code § 321J.2(1)(a )–(c ) (2011) (emphasis added).
For cases involving impairment by drugs, local law enforcement agencies in Iowa used special techniques for drug recognition testing. For instance, all traffic officers with the Des Moines Police Department are certified to detect and apprehend drivers under the influence of alcohol.
In fact, the police department in Des Moines, Iowa, has three officers trained and certified as Drug Recognition Experts (more properly called Drug Recognition Evaluators). These DRE officers are often called upon to investigate drivers who are suspected of being under the influence of drugs or narcotics.
Section 321J.2(1)(c) for OWI Drugs
Iowa Code Section 321J.2 (1)(c) criminalizes driving with any amount of a controlled substance in one’s system. The term “any amount” means any amount greater than zero. The “any amount” provision avoids proof problems for the prosecutor in determining the level of a controlled substance in the driver’s blood or urine and whether the drug impaired the ability to drive. Id.at 776.
The minimum levels of a controlled substance required for proof of a detectable or measured amount are listed in 661 I.A.C. 7.9 (321J).
History of Iowa OWI Drug Statute
Iowa Code section 321J.2 makes it a crime to operate a motor vehicle while under the influence of alcohol or drugs. Section 321J.2 was amended in 1998 to create a per se ban on driving with any amount of a controlled substance in the body regardless of whether a person is “under the influence” of that controlled substance. State v. Comried, 693 N.W.2d 773, 775–78 (Iowa 2005). See Iowa Code § 321J.2(1)(c).
A controlled substance is defined as any drug, substance, or compound that is listed in Iowa Code section 124.204 or 124.206, or any metabolite or derivative of the drug, substance, or compound. Iowa Code § 321J.1(4).
The distinction between this alternative and the first alternative discussed is that not all drugs are considered to be controlled substances as listed in Code section 124.204 or 124.206. In other words, impaired driving may occur through the use of drugs that do not fall into the specific controlled substance definitions. See, e.g., State v. Bond, 493 N.W.2d 826 (Iowa 1992).
An impaired driver taking prescription medication may be able to assert an affirmative defense. Iowa Code § 321J.2(7).
