Prescription Drugs and DWI

DWI (driving while intoxicated or driving while impaired) is most often associated with alcohol.

But under Chapter 49 of the Texas Penal Code, a person who drives a vehicle after taking a prescription drug may be arrested for DWI if the police believe the driver is impaired, even though the driver may not have consumed any alcohol and even though the medication was prescribed by a doctor and taken in the dose prescribed.

Many prescription drugs are actually controlled substances regulated by the federal and state governments. The use of some prescription medications — even without any alcohol or illegal "street" drugs — may result in a DWI charge for "drugged driving." If a person mixes a prescription drug with alcohol, he or she may be charged with both drugged driving and drunk driving.

In Texas, drugged driving and drunk driving convictions impose the same criminal and administrative penalties, which may include jail time, expensive fines, probation, driver's license suspension, and more.

DWI in Lewisville, Texas

Under the Texas Penal Code, Title 10, Chapter 49, § 49.04, a person may be charged with DWI, DUI or driving under the influence of alcohol, drugs or a controlled substance in Lewisville, Texas if he or she "operates a motor vehicle while intoxicated in a public place."

Definitions of Terms Related to Prescription Drugs and DWI in Texas

Section 49.01(2) of the Texas Penal Code defines "intoxicated" as "not having the normal use of mental or physical faculties (due to the consumption of) alcohol, a controlled substance, a drug, a dangerous drug, or a combination of two or more of those substances" or "having an alcohol concentration of 0.08 or more."

A "motor vehicle" is defined in §32.34(2) of the Texas Penal Code as "a device in, on, or by which a person or property is or may be transported or drawn on a highway, except a device used exclusively on stationary rails or tracks." Under this definition, motor vehicles include cars, trucks, motorcycles, boats, water scooters, airplanes, helicopters and even riding lawn mowers, but not trains.

In addition, a person must have "actual physical control" of a vehicle in order to be "operating" the vehicle.

Prescription Drugs in Texas

If a driver is suspected of operating a motor vehicle while under the influence of a prescription medication, the police will seek to test the driver's blood for the presence of any drugs or controlled substances. It does matter when the driver ingested the drug as long as its presence is detected in the test, even though the physical effects of many drugs dissipate before the body flushes all remnants of the drug from the system.

Some of the prescription drugs most often found in DWI toxicology tests include:

  • Ambien (Zolpidem)
  • Codeine
  • Darvocet (Dextropropoxyphene)
  • Hydrocodone
  • Lortab (Vicodin)
  • Morphine
  • Oxycontin (Oxycodone)
  • Percocet (Oxycodone with Acetaminophen)
  • Xanax (Alprazolam)
  • Other Prescription Pills and Medications

Blood Tests and Implied Consent in Texas

Officers from the police, sheriff or Texas Highway Patrol may seek to conduct blood tests during DUI investigations to determine the presence of drugs in a driver's system if impairment due to drugs is suspected.

These tests are allowed under Texas' "implied consent" law, because by accepting a driver's license from the State of Texas, a driver consents to chemical tests for intoxicants when requested by the police. A person may refuse to take a DUI blood test, but the refusal of a test will result in an automatic administrative driver's license suspension (which may be appealed).

In certain cases, such as a serious accident causing bodily injury or death, the police may obtain a search warrant to withdraw blood and do so even if a person refuses to be tested (See Texas Transportation Code, § 724.013). Anyone who withdraws blood from a DWI suspect must be qualified to do so and the equipment used must be certified as accurate.

Blood testing is not foolproof. Inaccuracies in the way a test is conducted may occur. A knowledgeable DWI attorney may be able to find problems with way a test is conducted, the person who conducted the test or the testing equipment. Any of these scenarios may result in the results of the blood test being excluded as evidence in a criminal DWI trial.

In addition, blood tests may reveal substances that may still be present from previous use. They do not directly indicate the driver was under the influence or intoxicated by drugs at the time of the arrest. An experienced DUI attorney may be able to argue that the mere presence of drug residue in the blood is not necessarily indicative of legal intoxication at the time of arrest.

Client Testimonials

I can’t say enough great things about the attorneys at this law firm. Within a few months they had my case, which I thought I was going to lose, dismissed and put my life back on track. I would recommend their firm to anyone and everyone who is in need of legal help.

Leslie L. Denton County DWI

A few months before I moved out of Texas, I was arrested for DWI. The problem was I was building a new life in another state with greater opportunities. I needed to find an attorney to handle my special situation being an out of state client who also travels out of the country. My case was in Denton County, which I have heard is a very difficult county to deal with. Because of my job I was in need of special accommodations from the court so I would not lose my career. After several months of tough negotiations with the DA, Richard and Brian were able to finalize my case beyond my expectations. I would highly recommend this law firm to anyone who has run into some trouble anywhere they might get a DWI.
