You're Innocent Until Proven Guilty — We'll Stand by You GET IN TOUCH

DUID Lawyer in St. Louis, Missouri

Driving under the influence of drugs (DUID) is a serious offense. At Eisenhauer Law, we understand the stress and anxiety that accompany a DUID charge We're here to help you understand DUID laws and provide the best defense possible. 

Driving under the influence of drugs involves operating a motor vehicle while impaired by illegal drugs, prescription medications, or even over-the-counter drugs. Unlike DUI, which generally refers to alcohol, DUID covers a broader range of substances. DUID-related impairment can decrease reaction times, affect judgment, and lead to dangerous driving situations.  

Types of Drugs Involved in DUID

  • Illegal drugs such as marijuana, cocaine, and heroin 

  • Prescription medications like painkillers, sleeping pills, and anxiety medication 

  • Over-the-counter drugs such as cough syrup or allergy medication 

  • Stimulants such as methamphetamine and Adderall 

  • Depressants like benzodiazepines and barbiturates 

  • Hallucinogens, including LSD and psilocybin 

  • Inhalants such as nitrous oxide and certain household chemicals 

  • Synthetic drugs like synthetic cannabinoids (e.g., "spice") and synthetic cathinones (e.g., bath salts) 

Note that even if a drug is legally prescribed by a doctor, it can still result in a DUID charge if it impairs your ability to drive safely.

How Is DUID Determined?

Unlike DUI, where breathalyzer tests can measure blood alcohol content, determining DUID often requires more comprehensive testing and observation. Law enforcement officers may conduct field sobriety tests, which assess a driver's coordination, balance, and cognitive function.  

These tests help officers identify signs of impairment that are not solely linked to alcohol. Officers might also employ a Drug Recognition Expert (DRE) to conduct a detailed evaluation that includes interviews, physiological checks such as eye examinations, and testing blood or urine samples to detect the presence of drugs in the system.  

Lab analysis of these samples can confirm the type and concentration of drugs used, further supporting the case for impairment. The combination of these methods aims to create a thorough and accurate assessment, ensuring that the drivers who pose a risk due to drug impairment are appropriately identified and charged. 

DUID Laws in Missouri

There are some legal aspects of DUID you should be aware of: 

  • Impairment standard: Missouri law considers you guilty of DUID if you are under the influence of any drug to a degree that impairs your ability to safely operate a vehicle. 

  • Zero tolerance for minors: If you're under 21, any detectable amount of drugs in your system can lead to DUID charges. 

  • Prescription medications: Just because a drug is prescribed by your doctor doesn't mean you're safe. You can still face DUID charges if it impairs your ability to drive. 

  • Penalties: In Missouri, penalties for DUID can range from fines and license suspension to jail time, especially for repeat offenders. 

  • Implied consent: By driving in Missouri, you automatically consent to blood, breath, or urine testing if law enforcement suspects you of DUID. Refusal to submit to these tests can result in immediate license suspension. 

  • Administrative actions: In addition to criminal penalties, you may face administrative actions such as points on your driving record and mandatory participation in drug education or treatment programs. 

  • Ignition interlock devices: The court may require the installation of an ignition interlock device (IID) for certain offenders. This device prevents the vehicle from starting if drug use is detected. 

  • Commercial drivers: Those holding a commercial driver’s license (CDL) face stricter regulations and more severe penalties, including longer suspension periods and the potential loss of their commercial driving privileges permanently. 

  • Probation and rehabilitation: First-time offenders might be eligible for probation or rehabilitation programs, which could lead to reduced penalties if completed successfully. 

  • Enhanced penalties: If driving under the influence of drugs results in an accident-causing injury or death, the penalties are significantly more severe, including potential felony charges. 

The Consequences of a DUID Conviction 

A DUID conviction can have severe consequences, impacting various aspects of your life. These include: 

  • Legal penalties like steep fines, jail time, and community service. 

  • Driver's license suspension, affecting your daily life and commute. 

  • Insurance rates skyrocket after a DUID conviction. 

  • Employment can be difficult to find with a criminal record. 

  • Personal life takes a hit as the stigma of a DUID conviction strains personal relationships and destroys your reputation. 

  • Educational opportunities may be limited by a conviction, impacting acceptance into programs and long-term career goals. 

  • Professional licenses, such as those for teaching, medical practice, or law, may be impacted by a DUID conviction, which could jeopardize your standing and ability to practice. 

  • Travel restrictions may apply with a criminal record denying you entry to certain countries, affecting both personal and professional travel plans. 

  • Financial strain can cause significant financial burdens with legal fees, fines, increased insurance rates, and potential loss of income. 

  • Probation requirements such as regular drug testing, counseling, or educational programs can be time-consuming and stress-inducing. 

  • Loss of public assistance in some cases can add a layer of financial hardship. 

Common Defenses in DUID Cases

There are several defenses that we may employ in your DUID case:

  • Improper traffic stop: If the police had no valid reason to stop you, any evidence they gathered might be inadmissible. 

  • Faulty testing procedures: Drug tests must be conducted and analyzed correctly. Any deviation from standard procedures can be challenged. 

  • Prescription defense: If you were taking medication as prescribed and not impaired, this could be a valid defense. 

  • Lack of impairment: Simply having drugs in your system isn't enough. The prosecution must prove that these drugs impaired your ability to drive safely.
