DWI On THC, Delta-8, Or CBD Lawyer In Conroe, TX
Hemp drinks, delta-8 vapes, THC gummies and CBD tinctures are sold in stores across Texas, and a driver arrested after using one is charged under the ordinary DWI statute. This page covers what the state must prove, what blood testing can and cannot show, the penalties and the defenses.
What Is A THC Or Delta-8 DWI In Texas?
A DWI after using a hemp THC, delta-8 or CBD product is charged under Penal Code § 49.04. Intoxicated includes losing normal use of mental or physical faculties because of a drug or any other substance. Whether the product was legal to buy does not decide the case. The state must prove impairment while driving.

Understanding Texas Law
How Does Texas Law Define A THC, Delta-8 Or CBD DWI?
A driver charged after using a hemp THC, delta-8 or CBD product faces an ordinary DWI under Penal Code § 49.04. The statute has no exception for lawful products. Its question is whether the driver lost the normal use of mental or physical faculties because of something introduced into the body.
The definition in Penal Code § 49.01(2) ends with the words "any other substance." That wording reaches a product sold legally at a convenience store or smoke shop the same way it reaches a prescription or a street drug.
How Texas Regulates Hemp
House Bill 1325, passed in 2019, created the Texas hemp program. It defines hemp as cannabis with no more than 0.3 percent delta-9 THC on a dry weight basis and removed hemp from the definition of marihuana in the Texas Controlled Substances Act. Growing and processing fall under Agriculture Code chapters 121 and 122, and consumable hemp products under Health and Safety Code chapter 443.
Those laws decide what can be grown, sold and possessed. None of them carves anything out of the DWI statute.
What the state must prove beyond a reasonable doubt:
- The person was operating a motor vehicle
- The vehicle was in a public place in Montgomery County
- The person had lost normal use of mental or physical faculties
- The loss was caused by a substance, such as a THC product
Products that come up in these arrests include hemp derived delta-9 THC gummies, seltzers and chocolates, delta-8 vape pens and edibles, other hemp derived cannabinoids, and CBD oils and capsules, some of which contain THC.
Delta-8 has been the most disputed. In 2026, the Supreme Court of Texas ruled in Texas Department of State Health Services v. Sky Marketing Corp. that the department had authority to list manufactured delta-8 THC as a Schedule I controlled substance. A product's status on the date of the arrest has to be checked for any separate possession question.
Penalties And Consequences
What Are The Penalties For A THC Product DWI In Texas?
The product does not set the penalty. The driver's DWI history and the facts of the arrest do. These are statutory limits, not predictions for any one case.
Class B misdemeanor.
Up to $4,000 with one prior, as a Class A.
- Classification
- Class B misdemeanor for a first DWI under Penal Code § 49.04. Class A with one prior conviction, third degree felony with two.
- Jail
- 72 hours to 180 days on a first offense.
- Fine
- Up to $2,000 on a first offense, plus court costs.
- The product itself
- Depending on what it was and its status at the time, a separate possession question can arise next to the DWI.
- License
- An administrative suspension through ALR, running apart from the criminal case.
- Blood testing
- A breath instrument cannot detect THC, so the case often turns on blood. A driver who refuses a breath test does not end the testing. The officer contacts an on-duty prosecutor who drafts a blood search warrant, an on-call judge reviews it for probable cause, and if signed, blood is drawn by a nurse over the driver's objection.
- Record
- A conviction is a permanent public record and counts as a prior for any later DWI.
Real Questions
What Do People Ask About THC And Delta-8 DWI In Texas?
Is there a legal THC limit for driving?
Why can a THC test come back positive days after use?
What if the label said CBD only?
Does a medical card or doctor's recommendation change the charge?
Why does a No Refusal weekend matter in a THC case?
Possible Defenses
How Can A THC Or Delta-8 DWI Be Defended?
Cannabinoid cases depend on science that is easy to misread. An attorney reviews the lab file, the officer's observations and the paperwork around the blood draw to see what the state can prove. No result can be promised.
A blood test looks for particular compounds. Hemp delta-9 THC and marijuana delta-9 THC are the same molecule, so no blood test can say which one a driver used. Delta-8 is a different compound, but a report separates it from delta-9 only if the lab's method was set up to do so.
A positive test is evidence of use, not proof of impairment.
The officer's observations still matter. Red eyes and nervousness also appear in people who are not impaired, and roadside tests built for alcohol were not designed to measure cannabis effects.
Brennon Mitchell is an ACS-CHAL Forensic Lawyer-Scientist, trained in the forensic chromatography labs use to measure alcohol and drugs in blood. That training helps in reading a lab report. It does not decide how any one case ends.
Which Compounds Were Tested
Did the lab look for delta-8, delta-9 or only a metabolite, and by what method?
Active THC Or Metabolite
Does the result show active THC near the time of driving, or only a lingering breakdown product?
The Product Itself
What was it, what did the label claim, and what did it contain?
The Officer's Observations
Do the signs described fit cannabis effects, or ordinary nerves and fatigue?
The Blood Warrant
Does the affidavit show probable cause, and was the draw done under protocol?
Causation
Can the state tie impairment to the substance and not to illness, fatigue or another cause?
The cannabis rules that overlap with these cases are on the marijuana DWI page, and the broader substance groups are on which drugs lead to a DWI charge.
Local Process
What Happens After A THC Product DWI Arrest In Montgomery County?
Warrants, booking and the license deadline work the same way throughout Texas. The court, the prosecutor and the jail are particular to Montgomery County.
The Stop And Investigation
The officer observes the driver, may request field tests and may call a drug recognition evaluator where one is available.
Blood Specimen
The officer asks for consent or seeks a warrant. A refusal carries a license consequence and, in a No Refusal period, can lead to a warrant draw.
The 15 Day ALR Window
The driver asks for an ALR hearing within 15 days after receiving the notice of suspension. The State Office of Administrative Hearings holds it by telephone or videoconference.
Lab Results And Charging
Blood testing can take weeks. The charge is filed or refined after the report arrives, and the defense asks for the full lab file through discovery.
- Where it is filed
- Filed in one of the Montgomery County Courts at Law, with Montgomery County District Attorney's Office handling the case.
- Arrests
- Made by Conroe Police Department, Montgomery County Sheriff's Office, Texas DPS Highway Patrol, Montgomery County Constables, Precincts 1 through 5, Willis Police Department, Shenandoah Police Department, Oak Ridge North Police Department, Magnolia Police Department, Splendora Police Department, or Roman Forest Police Department.
- Booking
- The Montgomery County Jail at 1 Criminal Justice Drive.
- If the case is appealed
- Appeals go to the Ninth Court of Appeals in Beaumont.
The license case runs through an ALR hearing, separate from the criminal case.
Next Steps
What Should You Do After A THC Product DWI Arrest?
A hemp product case has the same deadlines as any DWI, plus questions about the product. These steps are general information, not advice for any one person.
Count 15 Days
Find the date on the notice of suspension and count 15 days for the ALR hearing request.
Keep The Product And Receipt
Keep packaging, receipts and batch numbers. Do not discard or reuse the product before talking to a lawyer.
Write Down Timing
Note what you took, how much and when. Dose and timing matter to impairment questions.
Gather Medical Records
If a doctor recommended the product, keep that record.
Do Not Discuss It Online
Posts and messages about use can be read by the state.
Wait For The Lab Report
Do not assume the result. The full lab file can differ from a summary.
Speak with a lawyer before making any decision. Hemp law keeps shifting, and the product and the full lab report can both change the picture. Mitchell Law Firm offers a confidential conversation about a THC, delta-8 or CBD DWI charge in Montgomery County, and an early call keeps the most options open.

What does that mean for you?
It means when the state uses blood alcohol or drug testing to try to prove its case, Mr. Mitchell knows how to challenge it. He's trained to:
- Analyze lab results and spot faulty science
- Cross-examine forensic experts with precision
- Break down complex chemical evidence in plain language for juries

Common Questions
THC Product DWI Questions People In Conroe Ask
Can a hemp gummy or delta-8 vape lead to a DWI in Conroe, TX?
Penal Code § 49.01(2) defines intoxicated to include a loss of normal use of mental or physical faculties caused by a drug, a controlled substance or any other substance introduced into the body. A THC product falls within that wording whether or not it was lawfully sold. The state still has to prove the product impaired the driver at the time of driving.
Is delta-8 legal in Montgomery County?
Delta-8 THC has been fought over in Texas courts for several years. In 2026 the Supreme Court of Texas ruled in Texas Department of State Health Services v. Sky Marketing Corp. that the department had authority to list manufactured delta-8 THC as a Schedule I controlled substance. In a DWI case, legal status does not decide the outcome, because the offense turns on impairment.
Can CBD oil cause a THC result after a DWI stop in Conroe, TX?
CBD, short for cannabidiol, is not generally described as intoxicating. Many CBD products contain some THC, and labels on hemp products are not always accurate. A THC finding after CBD use can appear in a DWI case, and the questions then become what the product really contained and whether the driver was actually impaired.
Can a lab in Montgomery County tell hemp THC from marijuana THC?
Delta-9 THC from hemp and delta-9 THC from marijuana are the same molecule, so a blood test for delta-9 THC cannot show where it came from. Delta-8 THC is a different compound. Whether a given report separates delta-8 from delta-9 depends on the method and the compounds the lab tested for, which appear in the full lab file rather than the summary.
What happens after a refused blood test in a Conroe, TX THC product case?
A refusal after a Texas DWI arrest carries its own license consequence through the ALR process. During Montgomery County No Refusal periods, which cover weekends, holidays and announced enforcement periods, a refusal also leads a prosecutor to draft a blood search warrant for an on-call judge to review. A signed warrant allows a nurse to draw blood without consent.
What are the penalties for a THC product DWI in Conroe, TX?
The charge falls under Penal Code § 49.04 and carries the standard DWI range. A first offense is a Class B misdemeanor with 72 hours to 180 days in jail and a fine up to $2,000. One prior DWI conviction makes it a Class A misdemeanor, and two prior convictions make it a third degree felony.
