Maryland Drug DUI Lawyer
Maryland aggressively prosecutes DUI cases involving marijuana, prescription medications, and controlled substances—even if the substance is legal or taken as prescribed.
Drug DUIs are highly subjective, often relying on the judgment of a DRE officer and questionable “impairment signs.” We defend these cases with science-based strategies.
Types of Drug DUI Cases We Defend
- Marijuana DUI (THC) — including legal recreational or medical use.
- Prescription DUI — Xanax, Ambien, Adderall, pain medications, etc.
- DUI involving controlled substances — cocaine, opioids, benzos, stimulants.
- DUI with mixed substances — alcohol + marijuana, alcohol + medication.
- DRE officer cases — based on Drug Recognition Examiner evaluations.
A prescription or medical card is NOT a defense by itself in Maryland. The State only needs to claim you were “impaired.”
Marijuana DUI in Maryland (THC)
Maryland allows possession and use of recreational marijuana—but police still aggressively charge DUI for marijuana impairment.
Problems with marijuana DUI cases include:
- THC can remain in your system for days or weeks.
- Blood tests cannot show whether you were high at the time of driving.
- DRE evaluations are subjective and often flawed.
- Officers often misinterpret normal behavior as impairment.
For many clients, the strongest defense is exposing the lack of scientific reliability in the State’s evaluation.
Prescription Medication DUI
A very common Drug DUI scenario involves legally prescribed medications such as:
- Anti-anxiety medications (Xanax, Klonopin)
- Stimulants (Adderall, Ritalin)
- Sleep medications (Ambien)
- Painkillers (Oxycodone, Tramadol)
Even when taken exactly as directed, officers may claim signs of impairment based on nervousness, speech patterns, or roadside performance.
We often challenge these cases by connecting medical records, dosage timing, side-effects, and alternative explanations.
DRE Officers and the 12-Step “Drug Influence Evaluation”
Many drug DUIs depend heavily on the conclusions of a Drug Recognition Examiner (DRE).
The DRE 12-step protocol includes eye exams, pulse checks, muscle tone analysis, and “expert” interpretation. But:
- DRE training varies widely.
- Many officers do not follow all 12 steps.
- The protocol is subjective and unreliable.
- DRE findings are often contradicted by video.
Your defense begins by breaking down each step and documenting every deviation or mistake.
How We Defend Drug DUI Cases
- Challenge the traffic stop — no valid basis = suppression of evidence.
- Expose flaws in Field Sobriety Tests — many are not designed for drug impairment.
- Attack the DRE evaluation step-by-step.
- Challenge blood test reliability — contamination, timing, lab issues.
- Present medical explanations — anxiety, fatigue, neurological conditions.
- Use bodycam & dashcam to show normal behavior.
- Negotiate for non-impairment outcomes when appropriate.
Drug DUIs are beatable — especially when the State’s case depends on subjective interpretation.
Penalties for Drug DUI in Maryland
Penalties vary depending on prior offenses and the facts alleged:
- Possible jail time
- Fines and probation
- Mandatory treatment or education
- License suspension or interlock
- Insurance consequences
If the case involves marijuana, courts often focus more on treatment than punishment — but serious cases still require strong defense work.
