Drug DUI

Drug OVI Attorney in Columbus

Former Prosecutor Insight for Drug Testing & Impairment Allegations

We defend Columbus drivers accused of operating a vehicle under the influence of drugs. These Ohio OVI cases may involve alleged impairment, a prohibited drug concentration, or both. We examine the chemical-test evidence separately from the officer’s observations.

A charge may involve prescription medication, marijuana, an illicit controlled substance, or metabolites produced as the body processes a drug. If you need a DUID attorney in Columbus, we can review the traffic stop, blood or urine testing, license status, and pending court matter.

Call (614) 756-2154 for a free initial consultation about your Ohio drug OVI charge and the next steps in your case.

Personal Attention Backed by More Than 3,000 Cases

Our founding attorney, Douglas A. Funkhouser, has practiced law since 1995 and previously served as a U.S. Army prosecutor in South Korea. That background informs our methodical review of what the government must prove and where the evidence may be challenged.

Established in 2000, Funkhouser Law has handled more than 3,000 cases. Mr. Funkhouser personally handles each case, and clients receive their attorney’s cellphone number for direct 24/7 communication.

Our review may include:

Police reports and the officer’s account of the traffic stop
Cruiser video, body-camera footage, and field-sobriety testing
Blood or urine test documentation and laboratory records
Ohio Bureau of Motor Vehicles records and license-suspension notices

Prepare for a Free Initial Consultation

We offer in-person and virtual consultations, along with digital communication options. If you need a DUID lawyer in Columbus, gather any citation, test paperwork, license notice, and court documents you have. Reviewing those records can help identify which deadlines, filings, or license issues need attention first.

Ohio Drug OVI Charges Based on Impairment or Test Results

Ohio Revised Code Section 4511.19 allows the state to pursue different theories. One alleges that a drug of abuse impaired the driver. Another relies on a prohibited concentration of a listed controlled substance or metabolite in a qualifying specimen.

Each theory calls for a different evidentiary review:

Alleged impairment: The record may include driving conduct, statements, physical observations, field-sobriety testing, video, and medication information.
Prohibited concentration: The charge may depend on the substance, specimen type, reported concentration, collection timing, and threshold in the current statute.
Combined allegations: The prosecution may rely on observations and laboratory evidence, requiring each part of the record to be evaluated on its own terms.

Blood, Urine, & Laboratory Evidence

Ohio rules address testing for drugs, controlled substances, and metabolites in blood, urine, oral fluid, and other bodily substances. Results are generally reported in nanograms per milliliter, but a positive finding alone doesn’t establish whether the state can prove the charged legal element.

We may examine the specimen collected, its preservation, the testing method, and the laboratory report. We also review the chain of custody, which documents how the evidence was handled from collection through analysis.

Important laboratory questions include:

Does the report correctly identify the substance and specimen?
Were collection, storage, and preservation requirements followed?
Does the reported concentration correspond to the statute cited in the charge?
Does the result address impairment or only the presence of a drug or metabolite?

Ohio Per Se Limits Depend on the Substance & Specimen

Under a per se theory, a qualifying test result may support a charge without separate proof that the reported concentration caused impairment. Ohio Revised Code Section 4511.19 lists substance-specific concentrations for controlled substances such as amphetamine, cocaine, and heroin, as well as certain metabolites.

There isn’t one universal drug limit. The applicable threshold may differ among urine, whole blood, blood serum, and plasma. The specimen type and current statutory text are therefore central to the analysis. Marijuana-related provisions have also been subject to legislative change, so older threshold charts shouldn’t be assumed to reflect current law.

The Ohio BMV Matter Is Separate From the Criminal Case

An arrest can create two proceedings: a criminal prosecution and an administrative driver’s-license matter. Ohio’s implied-consent law governs qualifying chemical testing after an arrest for specified OVI offenses.

The Ohio Bureau of Motor Vehicles process may involve a suspension based on a test, an alleged refusal, and the notice issued after the arrest. Deadlines and available responses depend on the individual record, so we examine the license paperwork alongside the court filings.

The criminal case focuses on whether the prosecution can prove the charged offense. The administrative proceeding concerns driving privileges, and action in one doesn’t automatically resolve the other.

Drug OVI Cases in Franklin County Municipal Court

Franklin County Municipal Court hears misdemeanor criminal and traffic matters in Columbus, including OVI cases. We begin with the record filed or produced in the case rather than making assumptions based only on the drug named in the allegation.

Medical and prescription information may also be relevant, depending on the prosecution’s theory and the circumstances surrounding the arrest.

After an arrest, take these practical steps:

Keep the citation, license notice, test paperwork, and court documents together.
Record upcoming court dates and comply with all release conditions.
Avoid discussing the case or test results publicly or on social media.
Preserve information about prescriptions, medical treatment, and sample collection.
Provide available records to counsel for a case-specific review.
