Can Using Marijuana Impact My Texas Custody Case?

 Posted on October 29, 2026 in Child Custody

Marijuana use can become a source of conflict when parents disagree about their child’s care. An accusation of using drugs could lead to questions about your judgment and whether your home is safe.

Using marijuana can affect a Texas custody case, but it does not automatically decide the outcome. The court examines the circumstances and the child’s needs. If marijuana use is an issue in your child custody case in 2026, our Collin County, TX family law attorneys will help you understand your rights and respond.

Does Using Marijuana Automatically Mean You Will Lose Custody in Texas?

Marijuana use does not create an automatic rule that a parent loses custody. Under Texas Family Code Section 153.002, the child’s best interests must guide decisions about conservatorship and visitation.

The judge considers marijuana use alongside the parent’s caregiving history and the child’s need for stability. A claim of occasional use presents a different concern from repeated impairment that leaves a child without proper supervision.

A custody case is also separate from a criminal case. The family court does not need a criminal conviction before addressing conduct that threatens a child’s safety.

What Marijuana-Related Conduct Concerns Texas Custody Courts?

Conduct that exposes a child to harm or interferes with care gives the court a reason to consider safeguards. The concern is what happens while the parent is responsible for the child.

Examples include:

• Driving with the child while impaired
• Being unable to respond to a child’s needs because of intoxication
• Leaving edible products where a child could mistake them for food
• Exposing the child to smoke
• Allowing unsafe drug activity in the home

The child’s age also affects the risk. A toddler needs close supervision and protection from accessible products. An older child might face different concerns, such as riding with an impaired parent.

Does Medical Marijuana Use Receive Different Treatment in a Texas Custody Case?

Texas permits qualifying patients to receive prescribed low-THC cannabis through its Compassionate Use Program. Texas Occupations Code Section 169.003 sets requirements for those prescriptions. Lawful medical treatment should be distinguished from unauthorized marijuana use.

However, a prescription does not settle whether a parent is able to provide safe care. The court still needs to understand any effects on alertness or the ability to handle daily parenting duties.

Give your attorney documentation of the prescription and your provider’s instructions. Do not stop or change prescribed treatment solely to improve how your case looks.

What Happens if You Test Positive for Marijuana During a Texas Custody Case?

A positive marijuana test could lead the judge to require further testing or a substance use assessment before deciding your parenting arrangement. The court might also set temporary conditions while those concerns are addressed.

Your response should address what the result actually shows. A positive urine test does not establish exactly when you used marijuana or whether you were impaired during parenting time.

If you dispute the result, ask your lawyer about confirmation testing or other ways to challenge it. Follow any existing testing order while that dispute is pending. Missing a required test could create a separate compliance issue, even if you believe the original result was wrong.

What Parenting Restrictions Could a Texas Judge Order Because of Marijuana Use?

A judge could require supervised visits or place conditions on a parent’s time with the child. Depending on the concern, an order might prohibit impairment during parenting time or require testing and a substance use assessment.

Under Texas Family Code Section 153.193, restrictions must not go beyond what is needed to protect the child’s best interests. The terms should address the identified problem rather than serve as punishment.

For example, concerns about impaired driving could support limits on transporting the child. More serious supervision problems could justify having another responsible adult present during visits.

Read the order carefully before assuming that avoiding marijuana only during visits satisfies it. Some orders require abstinence for a longer period or impose other conditions.
