When most people hear the term DWI, they think of alcohol.
What many Arkansas drivers do not realize is that you can also get a DWI for prescription medication. In some cases, the medication involved was legally prescribed and taken exactly as directed by a physician.
That surprises many people.
However, Arkansas law focuses on impairment, not simply whether the substance involved was legal or illegal.
Understanding how DWI Drug cases work — like prescription-medication DWI cases — is important because they often look very different from traditional alcohol-related DWI prosecutions.

A Prescription Does Not Automatically Prevent a DWI Charge
Many people assume a valid prescription protects them from criminal liability.
Unfortunately, that is not always the case.
Arkansas law allows DWI charges when law enforcement believes a person’s ability to safely operate a vehicle has been impaired by a substance.
That substance may include:
- Alcohol
- Illegal drugs
- Prescription medications
- Certain over-the-counter medications
The legality of the medication does not automatically determine whether a DWI investigation occurs.
Instead, officers typically focus on whether they believe the driver’s ability to safely operate a vehicle was affected.
Common Medications Seen in Arkansas DWI Cases
Certain medications are more frequently associated with DWI investigations because they may affect alertness, coordination, reaction time, or judgment.
Examples often seen in these cases include:
- Xanax
- Adderall
- Oxycodone
- Hydrocodone
- Gabapentin
- Muscle relaxers
- Ambien
- Lunesta
- Certain anxiety medications
- Certain antidepressants
In some situations, the issue involves combining medication with alcohol, which can increase side effects and create additional concerns.
Symptoms Can Be Misunderstood
One challenge in prescription-medication DWI cases is that many symptoms associated with medications can resemble signs officers commonly associate with intoxication.
Examples may include:
- Drowsiness
- Dry mouth
- Bloodshot eyes
- Slurred speech
- Restlessness
- Confusion
- Dilated pupils
The problem is that these symptoms can also be caused by medical conditions, fatigue, illness, pain, or the underlying condition being treated.
As a result, interpreting those observations is not always straightforward.
Chemical Testing Is Different Than Alcohol Cases
Alcohol-related DWI cases often involve a BAC result that prosecutors use as scientific evidence.
Prescription-medication cases are often more complicated.
Blood and urine tests may reveal:
- Therapeutic levels of medication
- Trace amounts of medication
- Inactive metabolites
- Multiple substances
Unlike alcohol, many prescription drugs do not have a universally recognized legal limit associated with driving impairment.
That means the presence of a medication does not necessarily answer the central question of whether impairment existed.
Field Sobriety Tests May Become More Important
Because there is often no numerical threshold for prescription medications, officers frequently rely on observations and field sobriety testing.
Investigators may consider:
- Balance
- Coordination
- Divided attention
- Reaction time
- Driving behavior
These observations often become significant evidence in prescription-related DWI investigations.
Every Prescription-Medication DWI Case Is Different
Prescription-medication cases frequently involve medical issues that do not exist in traditional alcohol cases.
Questions may arise regarding:
- Dosage
- Timing of medication use
- Medical conditions
- Drug interactions
- Side effects
- Laboratory results
Those factors often make these cases more complex than many people expect.
