What You Should Know About DWI With Drugs

In Missouri, DWI charges extend far beyond alcohol. State law covers impairment by any drug—illegal, prescription, or over-the-counter—if it affects your ability to drive safely. Even if you have a lawful prescription or a medical marijuana card, you are not immune to prosecution if the substance impairs your driving. The prosecution must only prove that you were behind the wheel and that drugs impaired your ability to operate the vehicle safely.

The consequences of a drug-related DWI conviction can be both immediate and far-reaching. Here’s a breakdown of potential penalties:

• First offense: Up to 6 months in jail, fines up to $1,000, 90-day license suspension, and possibly ignition interlock requirements or substance use treatment.
• Second offense: Up to 1 year in jail, fines up to $2,000, 1-year license suspension, and mandatory ignition interlock device.
• Third and subsequent offenses: Felony charges, up to 4 years in prison, fines up to $10,000, and a 10-year license revocation, potentially with extended probation or treatment requirements.

Aggravating factors—such as having a child in the car or causing an accident—can increase these penalties and move a misdemeanor charge to a felony level. Every case we handle starts with a careful review of whether factors like prior DWI convictions or accidents are present.

Our clients are often surprised to learn that prescription and even over-the-counter drugs, if they impair you, are treated the same as illicit substances under Missouri’s DWI laws. Many common medications carry warnings related to drowsiness or coordination.

Testing and Implied Consent

Once you’re stopped for suspected DWI with drugs, law enforcement relies on several investigative tools to gather evidence. The testing process is notably different—and more subjective—than with alcohol-related cases.

• Field Sobriety Tests (FSTs): Officers may begin with standardized tests like the walk-and-turn, one-leg stand, and horizontal gaze nystagmus. While these were designed for detecting alcohol impairment, they’re routinely used for drug cases as well.
• Specialized Evaluations: Some officers hold advanced certifications (e.g., ARIDE or DRE) to identify drug impairment. Drug Recognition Experts (DREs) follow a 12-step protocol that reviews vital signs, physical symptoms, and behavioral cues. These assessments are highly subjective and frequently challenged in court.
• Chemical Testing: Breath tests cannot detect most drugs. Instead, officers must request a blood or urine sample—often administered at a hospital or medical facility after arrest. Samples are subsequently sent to a laboratory for analysis.

Missouri’s implied consent law states that, by driving, you have already agreed to submit to chemical testing if lawfully arrested for DWI. Refusing to comply with a blood or urine test after arrest results in immediate administrative consequences:

• An automatic one-year license suspension, completely separate from the criminal case
• The refusal being used as evidence against you in court
• Potential requirements for ignition interlock devices or additional penalties

We emphasize your rights throughout this process. Before arrest, you may refuse field sobriety tests, although officers may still find probable cause by other means. After an arrest, refusing the official chemical test triggers automatic penalties. Importantly, following officer-administered testing, you do have the right to request an independent examination of your own.

Unlike alcohol, drugs do not have clear, universally accepted threshold levels for impairment, making the results of blood tests open to legal and scientific challenge. Certain drugs, especially marijuana, can remain in your system for days or weeks after use without causing current impairment. Testing methods themselves can vary in accuracy, and proper handling is crucial—a chain-of-custody error or delayed analysis can cast doubt on the reliability of evidence.

What You Should Do If Charged

Being charged with a drug-related DWI in St. Louis County triggers both a criminal case and administrative actions against your driver’s license. Your immediate actions can determine your available defenses and the impact on your life. Focus on these key steps:

1. Know Your Rights
   • You have the right to legal representation—exercise this before making any statements, and before or after bond hearings and interrogations.
   • You have the right to remain silent—don’t discuss your case with anyone but your attorney and avoid any public comments or social media posts relating to your case.
   • You have the right to a fair trial—our firm ensures the prosecution meets their burden of proof and protects you from unfair tactics or assumption of guilt.
   • You have the right to review all evidence—we examine every police report, chemical test result, and witness statement as part of building your defense.
2. Know the Process
   • The criminal justice process following a drug-related DWI charge involves arraignment, pretrial motions, possible plea negotiations, and trial preparation, if needed. Having an experienced attorney on your side at every stage is crucial.
3. Document All Details Immediately
   • Write down everything you remember regarding your stop, arrest, interactions with police, and any field tests or blood draws. This record is critical as events fade from memory.
4. Comply with Release Conditions
   • Follow all bond, treatment, or driving restrictions set by the court, if any, to avoid additional charges or the loss of your release status.
5. Monitor Your Driver’s License Status
   • Request an administrative hearing within the required timeframe—often 15 days after arrest—to contest suspension. Our team can represent you in the hearing, help you seek limited driving privileges if applicable, or reinstate your license.
