Can Medical Marijuana Affect Your Houston Custody Case? What Matters Most to the Court

Texas has expanded access to low-THC cannabis through the Texas Compassionate Use Program (TCUP), allowing qualifying patients to obtain prescribed cannabis through the state-regulated system.

For a parent in a custody case, having a legal prescription does not necessarily end the conversation.

If your co-parent raises your medical cannabis use during a custody dispute, the court may look at the circumstances surrounding that use. Where did the cannabis come from? Are you following your prescription? Does it affect your ability to drive or care for your child? How is it stored in your home?

The focus in a Texas custody case is the child’s best interests. That means the facts surrounding your medical cannabis use can matter more than the prescription alone.

1. Are You Actually Participating in the Texas Compassionate Use Program?

Start with a basic distinction: Texas’s medical cannabis program is specific.

TCUP allows qualified physicians to prescribe low-THC cannabis to patients with qualifying medical conditions. Prescriptions are entered into the Compassionate Use Registry of Texas (CURT), and patients obtain products through licensed dispensing organizations.

If medical cannabis becomes an issue in your Houston custody case, being able to establish that you are participating in the state-regulated program can be important.

Useful documentation may include:

• Your prescription information in CURT
• Information identifying your prescribing physician
• Product labels and packaging
• Receipts or dispensing records
• Records identifying the licensed dispensing organization you use

Keep those records available rather than waiting until your co-parent questions whether the cannabis you use was legally prescribed.

2. Are You Using Medical Cannabis as Prescribed?

A prescription establishes why you have access to medical cannabis. How you use it can become a separate custody issue.

Suppose your physician prescribed cannabis for use at night, but your co-parent alleges that you regularly use it before driving your child to activities. Or your co-parent claims you use substantially more than prescribed.

Those allegations turn the dispute toward your actual behavior.

Evidence may include prescription instructions, dispensing records, communications between the parents, witness testimony, or specific incidents your co-parent claims demonstrate impairment.

Avoid treating “I have a prescription” as the complete answer to a custody allegation. Be prepared to document how your use compares with the treatment your physician prescribed.

3. Does Cannabis Affect You While You Are Parenting?

This may be one of the most important questions in the custody case.

The court can consider circumstances affecting a parent’s ability to provide safe and appropriate care. If medical cannabis causes impairment while you are responsible for your child, the issue can become relevant regardless of whether the medication was legally prescribed.

Think about your normal routine:

• When do you take your medication?
• Are your children usually with you at that time?
• Do you drive afterward?
• Could you respond if your child became sick or injured?
• Does another capable adult provide care while you are affected?
• Have there been any incidents involving your child’s safety?

A co-parent who simply disapproves of medical cannabis presents a very different factual situation from one who can identify specific incidents in which cannabis use allegedly affected the child’s care.

The same principle applies to other prescribed medications that can cause impairment. The custody question centers on what happens while you are responsible for your child.

4. How Is Medical Cannabis Stored in Your Home?

Storage can become especially important when children live in or regularly visit the home.

A parent using prescribed cannabis should consider whether a child can access it. The appropriate precautions can depend on the child’s age, abilities, and the type of product involved.

Products that resemble candy or food can create particular concerns. Keeping medical cannabis in its original labeled packaging and in a secure location can also help establish what the product is and where it came from.

If your co-parent alleges that cannabis was left where your child could reach it, photographs, messages, testimony, or other evidence concerning storage may become part of the custody dispute.

Review your storage practices before an issue occurs. A locked or otherwise secured location may be appropriate depending on your household and the product you use.

5. What Evidence Supports the Allegations About Your Cannabis Use?

Custody disputes can turn accusations into broad statements very quickly:

“They use marijuana around the kids.”

“They’re always high.”

“I don’t think the children are safe there.”

The details behind those statements matter.

If your co-parent raises medical cannabis use, your Houston custody attorney will want to know what evidence actually exists. That may include:

• Text messages or emails
• Photographs or videos
• Police reports
• Witness testimony
• Prescription and dispensing records
• Evidence involving driving or transportation
• Specific incidents involving the child
• Communications in which the parents previously discussed cannabis use

Your own communications matter as well. Arguments by text or social media posts about cannabis can become evidence and may provide a very different impression from medical and prescription records.

Preserve relevant communications rather than deleting messages after you learn that cannabis will be disputed.

Does the Medical Condition Behind the Prescription Matter?

Potentially. Every TCUP prescription is connected to a qualifying medical condition, so a custody dispute about medical cannabis can sometimes lead to questions about the condition being treated.

A parent might use low-THC cannabis for chronic pain, PTSD, multiple sclerosis, epilepsy, cancer, or another qualifying condition. The diagnosis itself does not establish whether that parent can safely care for a child.

If your co-parent claims your condition affects your parenting, the relevant questions may include:

• Whether symptoms affect driving or transportation
• Whether the condition limits mobility or physical caregiving
• How frequently significant symptoms occur
• Whether treatment controls those symptoms
• Whether you need assistance during certain periods
• Whether there have been specific incidents involving your child’s care

This can create a second sensitive issue in the case. You may find yourself addressing both your cannabis use and private medical information about why it was prescribed.

Before producing medical records or signing a broad authorization, talk with your Houston custody attorney about what information has actually been requested and how it relates to the custody allegations.

What Should You Do if Medical Cannabis Comes Up in Your Custody Case?

If you know your co-parent intends to raise your medical cannabis use, prepare for the specific questions the allegation creates.

Start by gathering documentation showing that your treatment is through TCUP and that the cannabis comes from a licensed dispensing organization. Review your prescription instructions, typical use, storage practices, and whether you ever use cannabis while responsible for transportation or other immediate parenting duties.

Also preserve communications with your co-parent that relate to the issue. A text exchange may show when an allegation first arose, what conduct was actually questioned, and how you responded.

Most importantly, tell your attorney about any incident your co-parent is likely to raise. That includes events you think were misunderstood or exaggerated. Your attorney needs the full context before deciding how to address the allegation.

A Quick Checklist Before Your Custody Hearing

If medical cannabis has become part of your Houston custody dispute, make sure your attorney knows:

• What qualifying condition is being treated
• Who prescribed the cannabis
• How your prescription is documented through TCUP
• Where you obtain it
• When and how you typically use it
• Whether it causes impairment
• How you handle driving and childcare after use
• How cannabis is stored in your home
• Whether your child has ever accessed it
• Which specific incidents your co-parent is alleging
• What records, messages, photographs, or witnesses relate to those allegations

This gives your attorney a clearer picture of the issue than simply saying that your cannabis use is legal.

Can Medical Marijuana Cost You Custody in Texas?

A TCUP prescription does not automatically determine the outcome of a custody case. The court’s broader responsibility is to make decisions based on the child’s best interests.

That puts the focus on the circumstances surrounding your use.

Evidence that a parent follows a legitimate prescription, stores the medication securely, avoids driving while impaired, and continues meeting the child’s needs presents one set of facts. Evidence of impairment during parenting time, unsafe storage, driving after use, or specific incidents affecting a child presents another.

The details of what actually happened will matter when the court evaluates whether cannabis use has any bearing on conservatorship, possession, or restrictions involving the child.
